Overview

The S3100 series is a multipurpose, outdoor, wireless, digital video product covering the

2.4 GHz and 5 GHz frequency bands in North America and Europe, and the 4.9 GHz public safety band in North America.

Note: The S3100 series devices require professional installation.

Verint Video Intelligence Solutions 1

1: Overview

About the S3100 Series

The S3100 series has many uses, including:

 Access point application—A communication hub for multiple S1100w devices  Point-to-point repeater—A range extender for one or many pairs of S1100 devices  Point-to-multipoint repeater—A range extender for multiple S1100w devices  Wireless bridge—A link between two networks (wired or wireless)  Wireless bridge repeater—A range extender for a wireless bridge

To cover these application types, the following S3100 models are available:

 S3100—A single device for access point applications  S3100-BR—Two devices for wireless bridge applications  S3100-RP—Two devices for repeater applications

Unless otherwise specified, the word S3100 refers to any of these devices. Every S3100 device comes with the following security features:

 SSL —Every edge device is shipped with a unique SSL (Secure Sockets Layer) certificate

for securing its IP link. SSL is a commonly used protocol for managing the security of IP message transmission. Therefore, the connections with another device or the SConfigurator tool can be secured.

If enabled, the SSL protocol secures the VSIP communication data. It does not apply to audio and video transmission.

Once a device is in secure mode, you cannot access it anymore with Telnet and you cannot perform firmware updates through the IP network on it. However, you can configure it with SConfigurator.

For more information about this security feature, refer to the SConfigurator User Guide.

 SPCF/SDCF—These proprietary MAC (Media Access Control) protocols use AES

encryption (with key rotation) over the wireless link to secure communication between the devices. They secure VSIP communication as well as audio and video data. For more information, see page 13.

System and RF Planning

To allow optimal configuration, you must properly plan your network, especially configuration layout and RF (radio frequency). Pla n ning is e specially r equired if y o u wan t to install many systems in the same area, in order to prevent radio interference between the colocated devices and to select the appropriate antennas. In all cases, follow the recognized RF installation practices.

Verint Video Intelligence Solutions 5

2: System and RF Planning

Available Frequency Bands and Channels

The S3100 supports communications in the following frequency bands, in North America and Europe:

 2.4 GHz OFDM, also known as 802.11g  4.9 GHz OFDM, a public safety band available in North America only  5 GHz OFDM, also known as 802.11a

2.4 GHz Band

The 2.4 GHz band provides 11 channels in North America and 13 in Europe. In these two regions, only channels 1, 6, and 11 are independent (that is, non-overlapping). All these channels are for indoor or outdoor use. The center frequencies of the channels are:

Channel Frequency (GHz) Channel Frequency (GHz)

1 2.412 8 2.447 2 2.417 9 2.452 3 2.422 10 2.457 4 2.427 11 2.462 5 2.432 12 2.467 (Europe only) 6 2.437 13 2.472 (Europe only) 7 2.442

4.9 GHz Band

The 4.9 GHz band is a licensed band for entities providing public safety services focused on the protection of life, health, or property in North America. This band provides license holders with an interference-free, secure channel for robust and secure broadband technologies, including wireless video surveillance systems.

For more detailed information concerning the regulations governing licensing and use of frequencies in the 4.9 GHz band, see Subpart Y of the FCC document, Memorandum Opinion and Order and Third Report and Order at:

http://hraunfoss.fcc.gov/edocs_public/attachmatch/FCC-03-99A1.pdf

The 4.9 GHz band has a width of 50 MHz (4940 to 4990 MHz). Since the standard channel width is 20 MHz, only two independent channels can co-exist in the band. However, the S3100 supports channel fragmentation, allowing narrower channels of 5 MHz and 10 MHz. You can have up to four independent channels with a 10 MHz width, and up to 10 with a 5 MHz width. All these channels are for indoor or outdoor use. For more information about channel fragmentation, see page 45.

6 Verint Video Intelligence Solutions

Nextiva S3100 Series User Guide

The available channels are:

Channel Frequency (GHz) Channel width

3 4.9425 5 MHz 6 4.9475 5 MHz 7 4.9525 5 MHz or 10 MHz 7 4.950 20 MHz 8 4.9575 5 MHz 9 4.9625 5 MHz or 10 MHz 10 4.9675 5 MHz 11 4.9725 5 MHz or 10 MHz 11 4.970 20 MHz 12 4.9775 5 MHz 13 4.9825 5 MHz or 10 MHz 16 4.9875 5 MHz

5 GHz Band

In the 5 GHz band, the number of available channels and sub-bands vary depending on the country of operation.

Most European countries adhere to the DFS (Dynamic Frequency Selection) and TPC (Transmit Power Control) regulations established by the European Telecommunications Standards Institute (ETSI); these regulations apply to the 5 GHz frequency band only. To know which bands are available in your country of operation and whether your country adheres to DFS and TPC, refer to the Wireless Frequency Plan document located on the Verint Video Intelligence Solutions extranet (Technical Support, then Downloads, then Utilities and Tools).

In North America, five channels are available in the 5 GHz band, all independent and for indoor or outdoor use. The center frequencies of these channels are:

Channel Frequency (GHz)

149 5.745 153 5.765 157 5.785 161 5.805 165 5.825

In Europe, the 11 independent channels, for indoor or outdoor use, are:

Channel Frequency (GHz) Channel Frequency (GHz)

100 5.50 124 5.62 104 5.52 128 5.64 108 5.54 132 5.66 112 5.56 136 5.68 116 5.58 140 5.70 120 5.60

2: System and RF Planning

Wireless Cells

A wireless network is designed such that information can travel back and forth between two points without the need for wires. Wireless devices are grouped into wireless cells. The devices in a cell communicate together on the same frequency channel and share the same wireless passkey (described on page 46).

Roles

An S3100 can have two MAC (Media Access Control) roles, according to its function in the wireless cell: master or slave. The other wireless devices (S1100, S1100w) that are connected to S3100 devices are clients. Clients always connect to a master S3100.

In this first example of a wireless cell, two S3100 devices, a master and a slave, form a wireless bridge:

Slave

The second example shows three wireless clients associated to an S3100 master device:

S3100

Wireless clients

You can colocate many wireless cells if you respect certain conditions (see page 20).

Master

Compatibility Issues

When planning your wireless systems, you need to take into account the firmware versions of the involved devices. It is recommended that the S3100 devices ha ve the same firmware versions as their associated slaves and clients; however, from version 2.60 and up, the devices are fully compatible (for example, an S3100 at version 3.20 with an S1100w at version 3.60).

8 Verint Video Intelligence Solutions

Nextiva S3100 Series User Guide

In a wireless cell involving S1100w transmitters, the order in which you configure the devices (either the first time or later when they are installed in the field) or update their firmware is critical if you do not want to lose access to them. You should then:

1. Update or configure the devices starting with the farthest (in terms of number of RF hops) from the computer running the upgrade procedure.

2. One step at a time, get closer to the host computer.

In a point-to-point repeater, you should:

1. Update the firmware of all S1100 pairs, starting with the remote device.

2. Change the IP address of the computer running SConfigurator (see page 37).

3. Update the firmware of the two S3100 devices.

For example, consider the following wireless cell:

S1100w 1

S3100 3 S3100 2

S3100 1

S1100w 2

You should update or configure the devices in the following order:

1. S1100w 1—You then lose contact with S1100w 1.

2. S1100w 2—You then lose contact with S1100w 2.

3. S3100 1—You can then reach all devices.

4. S3100 2—You then lose contact will all devices except master S3100 3.

5. S3100 3—You can then reach all devices.

For the complete firmware update procedure, refer to the SConfigurator User Guide.

Video Bit Rate and Data Throughput

You can connect up to 16 client and 7 slave devices to a master S3100 in a wireless cell. However, video quality, frame rate, and system layout can limit the number of devices that a single master device can support.

Verint Video Intelligence Solutions 9

2: System and RF Planning

Each time multiple client or slave devices are connected to a master S3100, the available bandwidth is divided equally between the connections. In the following example, two S1100w clients and one slave S3100 connected to a master on a 6 Mbps link each have 2 Mbps throughput.

S3100S3100

S3100

Note: In that context, you must ensure that all devices connected to a slave S3100 do not

require more than the available bandwidth. Otherwise video packets may be lost.

Furthermore, video quality and frame rate influence the required data throughput. Therefore, you need to carefully plan the number of cameras that will work on a link.

The following figures were measured in typical setup situations. They may vary depending on your configuration. The total data throughput in a unidirectional UDP link setup varies depending on two factors:

 The MAC protocol. For more information about SPCF and SDCF, see page 13.  The frequency channel width: 20 MHz in all available bands, or 5 MHz and 10 MHz in

the 4.9 GHz frequency band.

The S3100 automatically adjusts the transmission speed with the current RF conditions. For the bit rate requirements of the edge devices to which the cameras are connected,

consult the Bit Rate Settings for Video Servers document located on the Verint Video Intelligence Solutions extranet (Technical Support, then Downloads, then Utilities and Tools).

System Planning

The grouping of devices in each wireless cell is determined by their respective locations with respect to one another and by the available S3100 devices. As a rule of thumb, each client or slave device must have a clear RF line of sight with its master device within each cell. However, the client and slave devices can be completely hidden from one another. For more information about the RF line of sight, see page 25.

MAC Protocols

Depending on the type of applications, an S3100 device uses one of the two proprietary MAC protocols that solve problems inherent to 802.11 wireless networking products:

 The SPCF (SmartSight Point Coordination Function) protocol resolves the “hidden

node,” quality of service, range, and security problems. SPCF is used in access point applications and in repeater contexts. With this protocol, a master S3100 has total control over the radio frequency used; therefore, in an RF line-of-sight context, you cannot install two cells sharing the same frequency channel.

12 Verint Video Intelligence Solutions

Nextiva S3100 Series User Guide

 You use the SDCF (SmartSight Distributed Coordination Function) protocol in

point-to-point systems with a high volume of video transmission—typically ov er long distances or when a remote site is hard to reach—and in wireless bridge applications. SDCF optimizes the RF link by providing more data throughput. It also resolves the range and security problems of the 802.11 standard. However, SDCF does not manage the hidden node issue.

These two protocols are designed to work with Nextiva devices; they cannot work with wireless devices from other vendors.

Here is a typical context of use showing the two protocols. A access point system is installed on every floor of a multistorey parking building. The surveillance station is in another building. The SDCF cell acts as a wireless bridge between the two sites.

TPC

If the country of operation of the S3100 device requires conformity to the TPC (Transmit Power Control) regulations, the transmission power of its radio is automatically reduced by 3 dB before leaving the Verint factory. However, in case of a weak wireless link (that is, a link with an RF margin of less than 15 dB), you have the opportunity to use the maximum transmission power (see page 63).

DFS

To follow the DFS (Dynamic Frequency Selection) regulations specified by ETSI for the selected country, it is the master device that performs the tasks relative to frequency channel selection and radar detection. In other words, you cannot choose the frequency channel on which the edge device will run.

The automatic selection of the frequency channel limits the number and the configuration of the wireless cells. Furthermore, when colocating many cells, all masters must “see” each other.

Note: DFS is required only in the 5 GHz band.

You should start the master first, then power the client or slave when the other device is in normal operation.

Verint Video Intelligence Solutions 13

2: System and RF Planning

A master device in DFS mode goes through the following sequence when booting up:

Unit initialization (3 seconds)

Starting order delay (0-15 minutes)

Frequency scan (10-20 seconds)

Radar detection (60 seconds)

Radar detected?

Normal operation

Radar detected?

yes

1. The device goes through the standard startup procedure.

2. The starting order delay ensures that colocated masters will not select a frequency

channel at the same time, therefore minimizing the possibility that they choose the same one. For more information about the starting order, see page 64.

3. The device scans the available frequencies (based on the selected country) and automatically selects a channel. In the selection process, channels already used by colocated masters will be discarded at first.

4. The device listens for 60 seconds on the selected channel to detect possible radar interference.

5. If a radar is detected on the channel, the device returns to the scan process. Otherwise, it continues its bootup procedure.

6. The device runs normally.

7. If a radar is detected, the device immediately goes back to the scan process to select

another channel.

Nextiva S3100 Series User Guide

The boot sequence of client or slave devices is:

Unit initialization (3 seconds)

Roaming (2-25 seconds)

Normal operation

1. The device goes through the standard startup procedure.

2. The device roams through the channels in the available frequency bands to locate its

master.

3. When the master is located, the client or slave device runs normally on the selected frequency channel.

Application Types

The S3100 devices are used in many types of applications, including:  Access point—One S3100 device linking multiple S1100w transmitters to a LAN (the

S3100 model)

 Point-to-point repeater— Two S3100 devices acting as a range extender for one or many

pairs of S1100 transmitters (the S3100-RP model)

 Point-to-multipoint repeater—Two S3100 devices acting as a range extender for

multiple S1100w transmitters (the S3100-RP model)

 Wireless bridge—Two S3100 devices linking two networks, wired or wireless (the

S3100-BR model)

 Wireless bridge repeater—Two S3100 devices acting as a range extender for a wireless

bridge (the S3100-RP model)

Access Point

An access point application is a wireless cell made up of an S3100 device (the S3100 product code, called the master) and several S1100w transmitters (the clients). The MAC protocol for the master device is SPCF. Here is a typical access point system:

S1100w

S3100

Verint Video Intelligence Solutions 15

2: System and RF Planning

To install a single wireless cell made up of three S1100w transmitters and one S3100, you need to:

1. Assign the same wireless passkey to the S1100w and S3100 devices.

2. In a non-DFS context, assign a frequency channel to the S3100. In a DFS context, the

master device will automatically select a channel. The associated S1100w transmitters will automatically use their master’s channel.

3. Install the S1100w transmitters such that each one has a clear RF line of sight with the S3100 device.

For the complete configuration and installation procedures, see page 31.

Point-to-Multipoint Repeater

A point-to-multipoint repeater is used as a range extender for wireless links, when you need a device to retransmit the signals coming from S1100w transmitters towards the Ethernet LAN. A typical context is when you cannot obtain an RF line of sight between the transmitters and the S3100 connected to the wired LAN.

A point-to-multipoint repeater (the S3100-RP product code) is made up of two S3100 devices separated into two colocated cells. For example:

Master

To operate the two cells forming the repeater, you need to:

1. In each cell, assign the same wireless passkey to all the devices. The wireless passkey must be different from that of the other cell.

2. Always connect the S1100w transmitters to a master S3100, never to a slave.

3. Set the MAC mode of the S3100 in Cell1 to SPCF.

4. Set the MAC mode of the two S3100 devices in Cell2 to SDCF.

5. In a non-DFS context, assign a frequency channel to the master S3100 device in each

cell. For better isolation, use different frequency bands.

6. In a DFS context, set a different starting order for each master S3100. Ensure that the two masters see each other.

7. Install the S1100w and slave S3100 devices such that each one has a clear RF line of sight with its associated master.

For the complete configuration and installation procedures, see page 32.

Colocated Cells

You can operate many wireless cells in the same location, provided you follow guidelines relative to frequency band and channel, distance, wireless passkey, and location.

Distance Limitations

The distance limitations between devices are:  The minimum distance between two devices is 3 feet (1 meter), regardless of the band

or channel used.

 To avoid material damages, you must never power any two devices while their

antennas are facing one another with a distance of less than 10 feet (3 meters).

 In an SDCF cell, if the maximum distance between two devices is longer than 6 miles

(10 km), you must adjust the maximum link distance parameter; for more information, see page 64.

 If using adjacent channels, see page 83 for the recommendations on the minimum

distances to respect.

 To reduce radio interference possibilities between two adjacent frequency channels,

ensure that the maximum margin between the emission of the two wireless cells is 25 dB; for more information, see Appendix G on page 83.

General Guidelines

Regarding frequency channel, you cannot manually select one in the 5.40–5.725 GHz band in Europe; for the detailed procedure, see page 22. In the 4.9 GHz and 5 GHz band in North America and the 2.4 GHz band everywhere, the channel selection guidelines vary depending on the MAC protocol:

 When at least one SPCF cell is involved, you cannot use the same frequency channel.  Tw o SDCF cells can use the same frequency channel. They will share the available

bandwidth.

The wireless passkeys of colocated cells must be different from one another, regardless of their MAC protocols or frequency channels.

4.9 GHz Band in North America

Depending on the channel width (20, 10, or 5 MHz), you can colocate 2, 4, or 10 wireless cells respectively. For the available channels in each of the three scenarios, see page 7.

The following example presents three wireless cells with 10-MHz channels. To install such a system, you have to:

1. In each cell, assign the same wireless passkey to the S1100w transmitters and the S3100 access point. The wireless passkey must be different from that of the other cells.

20 Verint Video Intelligence Solutions

Nextiva S3100 Series User Guide

2. Assign a different frequency channel to each S3100 device; the associated S1100w devices will automatically use their master’s channel:

3. In each cell, install the S1100w devices such that each one has a clear RF line of sight with its associated S3100 access point.

This application can be illustrated this way, where the three cells are in the same location:

5 GHz Band in North America and 2.4 GHz Band

In the 2.4 GHz band in North America and Europe, you can use the three independent channels (channels 1, 6, and 11) to colocate wireless cells. In the 5 GHz band, all channels are independent.

A typical colocation example is three access point applications, each one made up of three S1100w transmitters and one S3100. To install such a system, you need to:

1. In each cell, assign the same wireless passkey to the S1100w transmitters and the S3100 device. The wireless passkey must be different from that of the other cells.

3. In each cell, install the S1100w transmitters such that each one has a clear RF line of sight with its associated S3100 device.

This application can be illustrated this way, where the three cells are in the same location:

Installing more than three cells in the 2.4 GHz band or more than nine cells in the 5 GHz band requires more RF planning. In such a context, you should contact the Verint Video Intelligence Solutions project engineering group for assistance.

5 GHz Band in Europe

The maximum number of colocated cells corresponds to the number of channels in the available frequency bands that can be used outdoors. For instance, in most countries of Western Europe, you can have up to 11 colocated cells in the 5.40–5.725 GHz band. However, because the master devices must see each other in a DFS context, the variety of supported setups is limited.

22 Verint Video Intelligence Solutions

Nextiva S3100 Series User Guide

In this context, you can easily install up to five cells. By respecting the following steps, you can assume that the cells will not share the same frequency channel, making the complete bandwidth available for each one. You have to:

1. Assign a different wireless passkey to each cell.

2. Ensure that all S3100 masters “see” one another. For the procedure, see Appendix F on

page 79.

3. Position the devices so that there is at least 3 feet (1 meter) between each antenna.

4. In each master device, set a different starting order: 1 for the first device, 2 for the

device next to it, 3 for the third one, and so on.

Installing more than five cells in the 5.40–5.725 GHz band requires the use of adjacent channels. This situation demands greater distances between the antennas to reduce potential radio interference. Therefore, you should contact the Verint Video Intelligence Solutions project engineering group for assistance.

Supported Setups

The following colocated systems are supported in the 5.40–5.725 GHz band:  A point-to-point repeater for one or more pairs of S1100 devices, with or without

RF Planning

Successful operation of a wireless link depends on proper RF path planning and antenna installation. You have to install the devices in such a way that there is a clear RF line of sight between the two antennas.

Location Evaluation

The path between the two antennas must be free of obstacles that could disturb propagation. For very short link distances—less than 500 feet (152 meters)—you may be able to establish a working link despite partial path obstruction. However, radio waves will be in part absorbed and in part diffracted by the obstacles, therefore affecting link reliability. Because the reliability of such an installation is highly unpredictable, Verint does not recommend it. A path free of any obstacle is called an RF line-of-sight path.

To establis h an RF line-of-sight path, you must take into account the beam width of the radio signal transmitted between the two antennas. This beam width is an elliptical area immediately surrounding the visual line of sight. It varies in thickness depending on the length of the line of sight; the longer the length, the thicker the beam width becomes.

The region outlined by the signal beam width is known as the first Fresnel zone. The Fresnel zone is always thicker at the mid-point between the two antennas. Therefore what appears to be a perfect line-of-sight path between the base and a remote station may not be adequate for a radio signal; this is the difference between “visual” and “RF” line of sight.

Visual line of sight First Fresnel zone (F1)

Verint Video Intelligence Solutions 25

2: System and RF Planning

In practice, it has been determined that a radio path can be considered an RF line-of-sight path if it has a clear opening through 60% of the first Fresnel zone (or 0.6 F1). Here are values for 0.6 F1 for various signal path distances and frequency bands:

Distance (mi./km)

1 / 1.6 14 / 4.2 9.8 / 3.0 9.5 / 2.9 8.9 / 2.7 0 4 / 6.5 27 / 8.4 19.5 / 5.9 18.7 / 5.7 18 / 5.5 2 / 0.6 7 / 11.3 37 / 11 25.8 / 7.9 25 / 7.6 23.6 / 7.2 6 / 1.8 15 / 24 53 / 16 37.8 / 11.5 36.4 / 11.1 35 / 10.6 29 / 8.8

2.45 GHz (feet/m)

4.9 GHz (feet/m)

5.3 GHz (feet/m)

5.8 GHz (feet/m)

Earth curvature effect (feet/m)

For distances under seven miles, the earth curvature effect is negligible. However, for greater distances, you need to consider it in your calculations; for instance, for a 15-mile link in the 2.4 GHz band, the two antennas must be located 82 feet higher than the highest obstacle in the RF line of sight between them (that is, 53 feet for the Fresnel zone plus 29 feet for the earth curvature effect). For help, consult the Verint Video Intelligence Solutions Support group.

A common problem encountered in the field and related to the 0.6 F1 clearance rule is building obstruction. The proposed visual path may just barely clear a building but the RF line of sight will not. In such a case, the signal will be partially absorbed and diffracted. Increasing the height of the two antennas or the gain of the antennas are the only alternatives to improve the link quality.

Note: At 2.4, 4.9, and 5 GHz, radio waves are highly attenuated by dense foliage. A link

established in the fall or winter season may be adversely affected in the spring and summertime, if it is established below tree level.

Antenna Requirements

Verint offers many antennas to meet various distance requirements. You need to consider many factors when choosing an antenna, including the distance to cover, the RF bit rate, the radiated power (EIRP), and the frequency band. For systems located in North America on the 5 GHz band, you can use the Wireless System Margin Calculator located on the Verint Video Intelligence Solutions extranet (Technical Support, then Downloads, then Utilities and Tools).

The combined transmission power of the device and antenna must not exceed the maximum value established by your country’s regulations. To ensure that this maximum is not exceeded, enter the gain of the chosen antenna in the CLI (Wireless Communication menu) or SConfigurator (Wireless pane). The device will automatically take it into account and adjust its own transmission power accordingly at startup.

Note: Connecting an antenna with a gain higher than the calculated value contravenes your

country’s regulations. It is your responsibility to ensure that you respect the regulations in place. You can only use antennas certified by Verint.

Interference

In most countries, the 2.4 GHz band is not regulated by a government agency; this absence of frequency coordination can result in interference between various systems. For instance, if a link with an RF line of sight is subject to excessive video delay and very low frame rate (or possibly breakdown of video images), it could be due to interference. Fortunately, you have ways of adapting your setup to avoid interference:

 RF channel selection—The S3100 has 11 or 13 channels to choose from. In case of

interference, it is recommended to change channel until you find a clean one.

 Antenna selection—Replacement of the integrated antenna by a higher gain one can

significantly lower the interference from other radio systems. Replace the antenna if switching channels does not correct the problem or if all channels must be used to colocate several systems.

There should not be any interference in the 4.9 GHz band, since it is a licensed band with limited usage to public safety.

The 5 GHz band is less cluttered than the 2.4 GHz band, resulting in less potential interference from other wireless systems.

RF Exposure Considerations

In order to comply with the RF exposure requirements of CFR 47 part 15 in North America, the devices must be installed in such a way as to allow a minimum separation distance of 12 inches (30 cm) between antennas and persons nearby.

2: Configuring and Installing the Device

Installation of the Antenna

You install the antenna after the S3100 device is in place. The antennas provided by V erint are designed to be mounted on a mast or pole of 2–3 inch (5–7.5 cm) diameter.

To install the antenna:

1. Install the antenna above the device. If you bought your antenna from Verint, use the

supplied pole mount bracket. For illustrations of pole mount installations, see page 73.

2. Screw the SMA connector of the antenna cable to the main antenna port and tighten it with a 0.25-inch (0.6 cm) wrench.

Warning: Do not over-tighten to avoid damaging the connector. The recommended

torque is 8 lb.-in. (100 N-cm). You could use a calibrated SMA torque wrench (for instance, from the Pasternack company, available at www.pasternack.com).

Warning: Do not use the auxiliary antenna connector and do not remove its

termination cap.

3. Apply two or three layers of electrical tape around all RF connections. The antenna cable and connectors are weather-tight; however, vibration caused by the

wind will over time loosen the connectors and reduce the efficiency of the gaskets. The electrical tape will prevent this situation.

4. Carefully align the antenna with those of the other devices (S1100w clients or S3100) so that they have a clear RF line of sight.

5. T o improve the signal level between two devices, use the antenna alignment utility from SConfigurator.

Firmware Update

You can update the firmware of the S3100 devices with the SConfigurator utility or a video management software; for the detailed procedure, refer to the documentation of the software. The latest firmware files are available on the Verint Video Intelligence Solutions extranet (Technical Support, then Downloads, then Firmware Upgrades).

Warning: Firmware downgrade is not supported on any device. If you perform a

downgrade, any problem encountered will not be covered by your product warranty.

The only method to update the firmware is through an IP network connection. If this update procedure fails:

1. Restart the same procedure immediately .

2. If the problem persists, move the device so that it is in the same IP subnet as the host

computer, reboot it, then restart the procedure.

You should take into consideration the following facts regarding firmware update using the IP network:

 It can be deactivated in the command line interface (CLI).

50 Verint Video Intelligence Solutions

Nextiva S3100 Series User Guide

 Ensure that the IP link is stable before starting the procedure; therefore it is not

recommended to perform it over the Internet.

Quality of Service

Quality of Service (QoS) is a set of low-level networking protocols giving higher priority to more important data flows while ensuring that the less important ones do not fail. QoS is an essential technology for organizations rolling out a new generation of network applications such as real-time voice communications and high-quality video delivery.

In the Nextiva edge devices, the two available QoS flavors are Type of Service (ToS) and Differentiated Service Code Points (DSCP).

For QoS to be taken into account, the network infrastructure equipment (switches and routers) must support one of these protocols. If any of these devices does not support QoS, the QoS data will simply be processed as traditional non-QoS data. Furthermore, all Nextiva edge devices on a network must support the same QoS protocol (or no protocols at all).

You can set a priority flag to three data types coming out of an edge device: video, audio, and control. A QoS-enabled switch (or router) uses this flag to determine how the current data compares to what is currently going through it.

To set the QoS values, you need to go in the command line interface (CLI) of the device, access the Advanced > Quality of Service menu. For the procedure to access the CLI, see page 55.

 Flashing green-red LED not during a firmware update—The device is in backup mode.

You will need to start the firmware update procedure.

Duplicate Master Detection

The duplicate master detection problem occurs when two S3100 master devices—with at least one in SPCF mode—are using the same frequency channel and are seeing each other.

52 Verint Video Intelligence Solutions

Nextiva S3100 Series User Guide

More specifically , the problem is detected when the second S3100 is booting up. This device refuses to start its wireless operations (to prevent any interference with the working setup) and makes its three LEDs flash red (1-second intervals). In the CLI of the device, the Current SPCF Connection Status parameter turns to Duplicate master detected (accessed through Advanced >Communication Status and Statistics > Wireless Status). Furthermore, an error message is logged in the device.

The already running master will not change its behavior.

Finding a “Lost” S3100

Since the S3100 does not have a serial port, you may have difficulty accessing it if you do not remember its IP address or VSIP port. For instance, if you enabled security on the device, you cannot access it with Telnet; if you lost its VSIP port, you cannot locate it with SConfigurator.

To find a “lost” S3100 device, you need to use SConfigurator and the common VSIP port.

To find a lost S3100:

1. Open SConfigurator.

2. From the General tab, click Program Options.

3. Click Common to set the common VSIP port, then OK.

4. Click the Units tab.

5. Click Discover.

All devices on the network, regardless of their configurable VSIP ports, appear in the Units list. Locate the lost S3100 and write down its VSIP port and IP address in the form located at the end of its installation guide.

Setting Parameters with

the CLI

The S3100 devices come with a simple command line interface (CLI) for configuration purposes. The CLI is hierarchically organized, with menus, sub-menus, and individual options representing configuration parameters. Only the par ameters that you are likely to change are described.

Verint Video Intelligence Solutions 55

4: Setting Parameters with the CLI

Getting Started

You can use the Telnet utility , through SConfigur ator, to open the command line interface of the device.

To enter the CLI with Telnet:

Note: Ensure that your computer and the S3100 device are in the same IP subnet.

1. Open SConfigurator.

2. In the Units tab, discover the devices.

3. Select the desired device, then click Telnet.

The CLI main menu appears in the Verint Console window.

The CLI has a timeout that is triggered after three minutes of inactivity. When the timeout occurs:

 You lose access to the command line.  The “Thank you for using the Verint CLI” message appears at the command line.  The Verint Console window becomes disabled.  The Disconnect button switches to Connect.

4. To reactivate the CLI after a timeout, click Connect.

5. To work through the CLI menu structure, follow these guidelines:

 To ex ecute a command or open a menu, type in the corresponding letter or number,

then press Enter.

 To return to the previous menu, enter p.

56 Verint Video Intelligence Solutions

Nextiva S3100 Series User Guide

6. To end the CLI work session: a. Save the settings by entering s at the main menu, then pressing Enter. b. Exit the CLI by entering q at the main menu, then pressing Enter.

Depending on the changed settings, the device may perform a soft boot.

c. Close the Verint Console window.

Warning: Do not use the Disconnect button to exit the CLI, since it does not save

your settings.

Access Management

The Access Management menu takes care of user accounts (user names and passwords) and device security.

User Accounts

The User Accounts menu enables you to protect the configuration of the device by restricting its access with a user name and a password. Once the user account mode is activated, you need the user name/password combination to access the CLI through a Telnet session.

Security

The Security menu holds commands relative to the protection of the device.

Verint Video Intelligence Solutions 57

4: Setting Parameters with the CLI

It allows you to control:

 Firmware updates through the IP network  Access to Telnet  Global security profile  SSL

IP Firmware Update

You can prev ent firm w are updates to be perfor med on you r device through the IP network. By default, this type of update is allowed. Be aware that it is the only available update method for the S3100, since it does not have a serial port.

For more information about firmware updates, refer to the SConfigurator User Guide.

Telnet Session

By default, you can use Telnet to access the CLI of your device. To improve the security of your system, you may prohibit such an access. In this case, you will not have access to the device CLI anymore.

Global Security Profile

This command is available if the device has an SSL certificate. If you activate the global security profile, the device will only accept secure SSL connections. It also means that you cannot access the device anymore with Telnet and you cannot perform firmware updates through the IP network on it.

SSL Passkey

To secure a device with SSL, provided of course it has an SSL certificate, you need to provide a passkey. This passkey must be the same for all devices and the software tools to allow proper secure communication between them.

It is recommended to perform this operation in SConfigurator (version 2.55 or higher for the tool and the device).

58 Verint Video Intelligence Solutions

Nextiva S3100 Series User Guide

System Status

The system status information indicates the current values of internal S3100 parameters, including the firmware version.

Network

The Network menu allows you to configure several parameters to ensure the compatibility between the S3100 and its IP network.

For more information about these settings, contact your network administrator.

DHCP Configuration

DHCP (Dynamic Host Configuration Protocol) allows devices and computers connected to a network to automatically get a valid network configuration from a server. For more information about DHCP, see Appendix D on page 75.

You can set this option only if the S3100 is connected to a network that uses a DHCP server.

Local IP Address

The IP address is the identifier of the S3100 on the network. Its format is a 32-bit numeric address written as four numbers separated by periods. Each number is in the 0–255 range. Each device on a network must have a unique IP address.

Verint Video Intelligence Solutions 59

4: Setting Parameters with the CLI

Write down the final IP address in the form located at the end of the installation guide of your product.

Subnet Mask

The subnet mask is the binary configuration specifying in which subnet the IP address of the device belongs. A subnet is a portion of a network that shares a common address component. On TCP/IP networks, a subnet is defined as a group of devices whose IP addresses have the same prefix. Unless otherwise specified by your network administrator, it is recommended to use a subnet mask of 255.255.0.0.

Gateway

The gateway represents a network point that acts as an entrance to another network.

Warning: Never use the IP address of the device as the gateway value.

Ping Request

Ping is a basic Internet program that allows you to check that a particular IP address exists and can accept requests.

To ping a specific device:

1. In the Ping Request Send Buffer Size parameter, enter the buffer size (in bytes).

2. In the Ping Request Target parameter, enter the IP address of the device.

3. Execute the Ping Remote Address command.

Wireless Communication

The Wireless Communication menu contains a set of parameters relative to r adio frequency (RF).

60 Verint Video Intelligence Solutions

Nextiva S3100 Series User Guide

Basic Parameters

Passkey

The wireless passkey is a unique case-sensitive identifier enabling secure and encrypted RF communication in a wireless cell (that is, with the other slave devices and S1100w transmitters). The passkey length varies depending on the key entry format (presented on page 63):

 32 digits if hexadecimal  16 characters if string (default)

It is a good practice to change the default passkey during the configuration process.

MAC Mode

The two available MAC (media access control) modes are SDCF and SPCF. For more information, see page 12.

MAC Role

The MAC role represents the function of the device in the wireless system. Possible values are: Master (default) and Slave. For more information, see page 8.

RF Band

The following frequency bands are available:

 802.11a (5 GHz OFDM)  802.11g (2.4 GHz OFDM)  public safety (4.9 GHz OFDM)

Channel

If your devices are operating in a DFS environment, you cannot manually select the frequency channel; in this context, the displayed value of the Channel parameter is Auto.

On a master S3100 device in a non-DFS environment, you can either specify an RF channel manually or use the automatic channel selection. On a slave device, you can specify an initial value for the roaming process by which the device will find its master; however, this initial channel may not be the one used by the master device.

The channels available in North America are:

 1 to 11 in the 2.4 GHz band  3, 6, 7, 8, 9, 10, 11, 12, 13, and 16 in the 4.9 GHz band (list varies depending on the

channel bandwidth)

 149, 153, 157, 161, and 165 in the 5.8 GHz band

Verint Video Intelligence Solutions 61

4: Setting Parameters with the CLI

To know which channels are available elsewhere, refer to the Wireless Frequency Plan document located on the Verint Video Intelligence Solutions extranet (Technical Support, then Downloads, then Utilities and Tools).

Channel Bandwidth

In the 4.9 GHz band, the bandwidth can be fragmented to allow 5- and 10-MHz channels; the default channel width is 20 MHz. This parameter only appears if the RF band is 4.9 GHz. The list of available channels varies depending on the chosen bandwidth; for more information, see page 7.

Tx Bit Rate

The transmission bit rate is the data rate at which the device operates. A high bit rate reduces the effective distance between two functional devices.

You can set the bit rate in slave S3100 devices only. When a slave device connects to its master for the first time, it automatically receives the

best possible value (the Auto value), with a default RF margin set to 15 dB (to change the margin, see page 64).

Once the device is operating properly, Verint strongly recommends to change the configured bit rate from Auto to the actual bit rate of the connection. This way, the wireless communication will be more stable in the presence of changing atmospheric conditions or other RF interferers. To know the actual bit rate of the connection, look in the Advanced > Communication Status and Statistics > Wireless Status menu. If the quality of the RF link degrades severely, the actual bit rate could be lower that the manually configured one; when the quality improves later on (it is evaluated periodically), the bit rate will be automatically updated.

The available bit rates for the slave S3100 device are:

Band Channel width Bit rates (Mpbs)

2.4 GHz N/A 6, 9, 12, 18, 24, 36, 48, and 54

4.9 GHz 5 MHz 1.5, 2.25, 3, 4.5, 6, 9, 12, and 13.5 10 MHz 3, 4.5, 6, 9, 12, 18, 24, and 27 20 MHz 6, 9, 12, 18, 24, 36, 48, and 54

5 GHz N/A 6, 9, 12, 18, 24, 36, 48, and 54

Antenna Gain

If you enter the gain of the antenna you install on the device, the S3100 will be able to automatically change its transmission power so that the total power (edge device and antenna) does not exceed the maximum value established by your country’s regulations. For more information about the maximum antenna gain you can use, see page 26.

62 Verint Video Intelligence Solutions

Nextiva S3100 Series User Guide

ISO Country Code

You must assign the proper country of operation to the device, so that it will:

 Comply to the DFS/TPC regulations, if applicable  Respect the EIRP rules  Use the proper set of frequency channels

Advanced Parameters

The Advanced Wireless Setup menu contains specialized RF features.

Passkey Entry Format

The wireless passkey can have two formats: string (default) or hexadecimal.

Tx Power Scale

The transmission power scale indicates the level of emitting power of the device radio. The available values are:

 Maximum—The maximum allowed.  50%—The power is reduced by 3 dB.  25%—The power is reduced by 6 dB.  12.5%—The power is reduced by 9 dB.  Minimum—The power is set at 3 dBm.

Sensitivity Threshold

The sensitivity threshold is the minimum signal level perceived by the radio of the device. Reducing the sensitivity of the radio enables unw anted “noise” to be filtered out. A safe

value is 10 dB below the current received signal level (displayed in the Advanced > Communication Status and Statistics > Wireless Status menu).

The default value, Normal, represents the most sensitive context. You must be careful not to reduce the sensitivity to a level where the device would not “hear” its legitimate correspondent.

Verint Video Intelligence Solutions 63

4: Setting Parameters with the CLI

Starting Order

The starting order is a sequence number, used during the boot-up process of a master S3100 in a DFS context, to delay its startup. The purpose of this parameter is to ensure that colocated master devices will not start at the same time. The default starting order is

1. Every colocated cell should have a different starting order: It should be incremented by 1 in each system.

At the beginning of the boot sequence, the master device waits a specific number of seconds based on the value of this parameter. This wait period will ensure that no two masters will start at the same time and select the same frequency channel. This delay is: (order - 1) multiplied by 80 seconds.

The starting order has an impact only when the channel selection is automatic.

Minimum Margin

The minimum margin is used when the transmission bit rate is set to Auto. It represents the difference (in dB) between the actual signal received by the device and the minimum signal required by a given bit rate to correctly receive data on the RF link. The default minimum margin is 15 dB. You can change it only on slave S3100 devices.

Maximum Link Distance

The maximum link distance parameter appears when the MAC mode is SDCF. It specifies the maximum transmission distance, between any two devices, in all wireless cells present in the same geographical region and sharing the same frequency channel.

The two S3100 devices making up an SDCF wireless cell must have the same value for this parameter. Possible values are:

 3 miles (5 km)  6 miles (10 km)—default  9 miles (15 km)  12 miles (20 km)  15 miles (25 km)

For instance, consider the following setup, where the two wireless cells use the same frequency channel:

2 miles (3.2 km)

S3100 1

S3100 2

S3100 3

Masters

64 Verint Video Intelligence Solutions

S3100 4

15 miles (25 km)

Nextiva S3100 Series User Guide

Since the two masters are in RF line of sight, all devices must set their maximum link distance values to 15 miles (25 km). Otherwise packet collisions may occur , resulting in lost data.

Indoor/Outdoor RF Regulation

Depending on the country of operation and the chosen frequency band, the S3100 is allowed to operate indoors only , outdoors only, or either indoors or outdoors. The frequency channels available in the indoor-only regulation are different from those assigned to indoors/outdoors; the same goes for the outdoor-only channels.

Note: Under the RF regulation, a device programmed to be used only indoors must not be

installed outdoors, and vice versa.

To know which frequency channels are available in your country of operation in each of the three operation modes, refer to the Wireless Frequency Plan document located on the Verint Video Intelligence Solutions extranet (Technical Support, then Downloads, then Utilities and Tools).

The default factory value for most countries is indoor/outdoor.

Advanced

The Advanced menu holds a series of advanced setups mainly used by Verint Video Intelligence Solutions customer service. Some of these parameters are available through SConfigurator or a video management software.

Identifying a Device

To recognize an S3100 among a large set of devices, you can make its three LEDs flash red rapidly.

To identify an S3100 device:

1. From the main menu, choose Advanced, then press Enter.

2. Enter i to make the LEDs flash red. Re-enter i to set the LEDs to their previous state.

DHCP Support and

APIPA

DHCP (Dynamic Host Configuration Protocol) allows devices and computers connected to a network to automatically get a valid IP configuration from a dedicated server.

The APIPA (Automatic Private IP Addressing) scheme, available on the Windows operating systems, enables a device to assign itself a temporary IP address.

Verint Video Intelligence Solutions 75

D: DHCP Support and APIPA

At startup, an edge device searches for a valid IP network configuration. The device requires this configuration prior to starting its functions. The network configuration for Nextiva devices consists of:

 An IP address  A subnet mask  A gateway

The device first looks in its local memory. If no configuration is found, it tries to contact a DHCP server. If DHCP configuration fails—if the device does not find a server or if it cannot get a configuration from it within one minute—the device assigns itself temporary network settings based on the APIPA addressing scheme. This scheme allows a device to find a unique IP address until it receives a complete network configuration, either manually or from a DHCP server.

A device in APIPA mode does not reside on the same subnet as the other devices on the IP network; therefore, it may not be able to see them or be visible to them. Devices use the following temporary APIPA configuration:

 IP address: 169.254. *. *  Subnet mask: 255.255.0.0  Gateway: 169.254. *. *

The *. * portion is based on the MAC address of the device. A device is in APIPA mode:

 The first time it boots up  After receiving a duplicate IP address  After a hardware reset  When the DHCP server does not have any available IP addresses  After loading the default settings

DHCP configuration is automatically disabled:

 After a firmware upgrade  After a factory reset

Surge Protection

Voltage and current surges can be induced by lightning strikes or power line transients. In the real world, under the right circumstances, these surges can reach sufficiently high levels to damage almost any electronic equipment. Therefore you need to add protection to your devices.

Verint Video Intelligence Solutions 77

E: Surge Protection

VerintThe S3100 provides built-in surge protection on the Ethernet/PoE and 24V AC power connectors. The antenna connectors do not have surge protection; this situation should not cause problems as long as you keep the antenna cable short—that is, below 6.6 feet (2 meters).

If you are installing an S3100 model in a heavy lightning environment, or in a site where large AC mains power fluctuations are a common occurrence, Verint recommends that you add surge protection on the DATA & PWR port of the PoE injector. It will protect your equipment and the power inserter from surges coming down from the Ethernet cable.

Using a surge protector is strongly recommended if the Ethernet cable runs outside the building for more than 82 feet (25 meters). This device should be installed at the entry point of the cable inside the building. To be effective, this protection equipment must be properly grounded.

PoE protectors recommended by Verint include:

Company Part number Web site

Citel MJ8-505-24D3A60 www.citelprotection.com Transtector Systems 1101-693 TSJ POE-48 www.transtector.com

For the curious mind, a surge protector helps to clamp the surge to safe levels and divert its energy to the earthing point, preventing device damage. Experienced installers know that an effective surge protection must be installed with proper earthing and grounding.

78 Verint Video Intelligence Solutions

RF Contact between

Masters

If the country of operation of your devices requires DFS compliance, you must ensure that the master devices (S3100 and S1100-R) in colocated cells “see” one another in their permanent location. Such a contact means that RF communication can be performed between each pair of masters, therefore preventing them to choose the same frequency channel.

Verint Video Intelligence Solutions 79

F: RF Contact between Masters

Apply the following procedure to ensure that MasterA sees MasterB. You will have to access the command line interface (CLI) of at least one master. For more information about the CLI, refer to Chapter 4 in the Nextiva S3100 Series User Guide or to Chapter 4 in the Nextiva S1100 User Guide.

To ensure that two master devices see each other:

1. Take down the device name of MasterB.

This name is displayed in the SConfigurator Units tab, in the Unit Information pane of the Configuration Assistant, or in the Advanced > VSIP menu of the CLI.

2. Shut down MasterB, then power it up.

3. Wait until MasterB has selected a frequency channel. To ensure that a channel is

selected:

 If MasterB is an S3100, go in the Advanced > Communication Status and

Statistics >Wireless Status menu of the CLI. Wait until the value of Current SCF Connection Status is Connected to X Clients and Y Slaves.

 If MasterB is an S1100, go in the Wireless Status window of the Configuration

Assistant. Wait until the connection status is Not Connected or Connected; these statuses occur after Radar Detection.

 If you do not have access to the connection status of MasterB, wait for the following

time period: (starting order of MasterB - 1) multiplied by 80 seconds.

4. Perform a site survey in MasterA: a. Open the CLI of the device. a. Go in the Advanced > Communication Status and Statistics > Wireless

Status menu.

b. Execute the Initiate One-Time Site Survey command.

80 Verint Video Intelligence Solutions

Nextiva S3100 Series User Guide

c. To see the progress of the operation, press Enter every second.

The site survey is completed when the value of Current SCF Connection Status returns to Connected to X Clients and Y Slaves, after having gone to Site

survey (100% completed).

d. Execute the Visualize Last Site Survey Report command. e. Check that the MasterB name is listed as the Unit Name of one of the channels. You

may need to scroll up the CLI window to see the beginning of the survey data. For example, in the following site survey, MasterB has a visual connection with the

MasterA device. If the MasterB name is not displayed in the site survey, it means that the two masters cannot see each other.

Separation Between

Devices Using Adjacent

Channels

Wireless interference can occur between wireless cells using adjacent frequency channels (for example, channels 149 and 153 in the 5 GHz band). Therefore, it is preferable to avoid using adjacent channels. However, if your setup requires you to, you must follow specific guidelines regarding minimum distances between antennas and signal level margin.

Note: In the 2.4 GHz band, the adjacent channel term applies only to the three

independent channels (1, 6, and 11).

Verint Video Intelligence Solutions 83

G: Separation Between Devices Using Adjacent Channel s

If using adjacent frequency channels in a non-DFS environment, you should respect guidelines relative to the minimum separation between device antennas, to avoid interference.

T o reduce radio interference possibilities between two adjacent channels, you should ensure that the maximum margin between the emission of the two wireless cells is 25 dB. To meet this objective, perform a site survey and apply minimum distance guidelines.

Performing a Site Survey

The difference in signal level between two adjacent cells must be less than or equal to 25 dB. If this margin is higher than 25 dB, there will be too much interference in the two adjacent wireless cells. To calculate this margin, you need to perform a site survey; for more information, see page 66. Here is an example of a 25 dB margin between channels 8 and 9 in the 4.9 GHz band:

Interference between the two channels

Consider the following setup in the 4.9 GHz band with 5-MHz bandwidth, where Cell B uses channel 6 and you are trying to add Cell A on channel 3 (adjacent to channel 6):

B3B2

A1B1

Cell B Cell A

To determine if this setup is feasible, you need to conduct a site survey on device A1 (the master device in Cell A), then calculate the margin between the two cells. During the site survey, device A1 will find the other five devices. With the provided signal levels, you need to check if S2 - S1 <= 25 dB, where:

 S1 is the lowest signal level in the wireless cell of the device performing the site survey

(A1 in the example).

 S2 is the highest signal level in the adjacent cell (Cell B in the example).

84 Verint Video Intelligence Solutions

Nextiva S3100 Series User Guide

To calculate the emission margin between two adjacent wireless cells:

1. Open SConfigurator, then go to the Units tab.

2. Select the master device in the wireless cell you are adding, then click Telnet.

3. From the main menu of the command line interface (CLI), choose Advanced > Communication Status and Statistics > Wireless Status, then press Enter.

4. For a thorough scan, specify 60 site survey iterations.

5. Start the site survey operation.

Note: During the execution, the RF link will be momentarily broken (duration varies

depending on the number of iterations). The link is automatically restored when the survey is finished.

Verint Video Intelligence Solutions 85

Cell B Cell A

The lowest signal in Cell A is -75 (S1) and the highest signal in Cell B is -45 (S2). The result of S2 - S1 (-45 - -75) is 30. Since the margin is higher than 25 dB, there will be interference issues.

Minimum Distances

To respect the 25 dB margin between two adjacent channels, in addition to performing a site survey, you can use guidelines relative to minimum distances between the wireless devices. By respecting them, you can assume that there will not be radio interference between the devices.

Three physical setups are covered:

G: Separation Between Devices Using Adjacent Channel s

The following deployment scenarios respect these limitations:  Using only 5 GHz channels, all on the same side of a building:

5.8 GHz 165

5.3 GHz565.8 GHz 157

5.3 GHz645.8 GHz 149

5.3 GHz 52

5.8 GHz 161

5.3 GHz605.8 GHz 153

43 feet (13m)3 feet (1m) each

Notice that the devices using the adjacent channels 52 and 56 are separated by the prescribed 43 feet (13m). However, you can intersperse other devices in-between, as long as they do not use adjacent channels. This way, you can increase the device density without encountering interference problems.

 In the 4.9 GHz band, using only 5 MHz channels, all on the same side of a building:

4.9 GHz 3

4.9 GHz 7

4.9 GHz 9

4.9 GHz 11

4.9 GHz

4.9 GHz 12

36 feet (11m)3 feet (1m) each

Notice that the devices using the adjacent channels 7 and 6 are separated by the prescribed 36 feet (11m). However, you can intersperse other devices in-between, as long as they do not use adjacent channels. This way, you can increase the device density without encountering interference problems.

 In the 4.9 GHz band, using only 10 MHz channels, all on the same side of a building:

4.9 GHz 7

4.9 GHz 11

4.9 GHz

36 feet (11m) 3 feet (1m) each

Since only four channels are available, it is unavoidable th at two adjacent chan nels are positioned next to each other.
