AWE 120-58 User Guide

Description

Features

The AWE 120-58 advanced wireless Ethernet bridge provides high-speed, wireless connectivity at a fraction of the cost of wired solutions. It operates over the 5.7250 – 5.8500 GHz ISM radio band and has a maximum raw wireless data rate of 12 Mbps.

• Provides wireless connectivity at speeds up to eight times faster than regular T1 lines, making the AWE 120-58 ideal for providing high-speed Ethernet access or for wirelessly extending existing communications infrastructures.

• Supports point-to-point, point-to-multipoint, and multipoint-to-multipoint networks (if all remotes have

clear line of sight to the base station and to each other). Contentionless polling ensures efﬁcient access to remote data networks.

• Is self-contained and easy to use. Simply connect an AWE unit to each LAN segment, and the unit

automatically learns where nodes are located on the network and performs dynamic packet ﬁltering to ensure the local LAN trafﬁc does not overload the wireless connection.

• Uses Wi-LAN's patented Multi-Code Direct Sequence Spread Spectrum (MC-DSSS) technology, which

makes the unit spectrally efﬁcient and resistant to interference. MC-DSSS technology increases data throughput by as much as ten times compared to traditional spread spectrum technology.

• Other features include automatic Tx power level adjustment, IP address ﬁltering, throughput throttling and

monitoring, high security and reliability, and a ﬂash-code upgrade path. SNMP, telnet and RS-232 management enable users to manage, conﬁgure and monitor their wireless network with ease.

• VLAN compliant—supports transparent forwarding of VLAN-tagged frames (increased frame size supported) and remote management of units within a VLAN environment (i.e. units connected via trunk links). Supports VLAN tag insertion/removal and VLAN supporting protocols (802.1D, 802.1P, GVRP).

About Spread Spectrum

Three frequency bands (called the ISM bands) are allocated in Canada and the United States to a radio technique known as spread spectrum communication. The bands are located at 900MHz, 2.4 GHz, and 5.8 GHz (shown in the following illustration). The AWE 120-58 operates with spread spectrum technology over the 5.7250 – 5.850 GHz band.

125 MHz Wide

5.725 GHz 5.85 GHz

Direct Sequence Spread Spectrum (DSSS) technology converts a data stream into packets and spreads the packets across a broad portion of the RF band. The particular spread pattern depends upon a code. With multi-code DSSS (MC-DSSS), multiple codes and spread patterns are employed. A spread spectrum receiver reconstructs the signal and interprets the data.

Some advantages of DSSS are as follows:

• Resistant to interference: DSSS overcomes medium levels of interference and multipath problems.

• Security: There must be a decoder at the receiving end to recover data (an AWE can only talk to

another AWE). Data is transmitted at irregular time intervals.

• Low probability of detection: Due to a low amplitude signal and wide bandwidth.

• No license fee: A license fee is not required if used in the speciﬁed radio bands and the transmitter

power is limited.

About AWE Units

AWE 120-58 units can function as base stations, remote units or repeater bases.

Base Station: One unit in your wireless network must be a base station. A base station acts as the central

control unit of the wireless network. The base station polls all remote units and controls how trafﬁc is routed to and from remotes. The base usually connects to a major access point of the wired network. The antenna of the base station must be capable of transmitting and receiving radio signals to and from all the remote units in a system. If remotes are spread over a large area, an omni-directional antenna is usually required. See

Configuring a Base Station

, page 15 for information about setting up a base station.

AWE 120-58 User Guide

Some System Applications

Remote Units: Remote units receive and transmit wireless data to the base station. You need at least one

remote unit for each wireless link. Remotes can limit the amount of data passed by the remote (a function called throttling), and they can ﬁlter data packets based on their IP address. If remote units communicate only with the base station, their antennas can be more directional and have higher gains than base antennas. See

Configuring a Remote Unit

, page 18 for information about setting up a remote unit.

Repeater Base: A base station can be conﬁgured as a repeater base. A repeater is needed when remote

units cannot communicate directly with each other, but direct transfers of data between them are necessary (as in a true WAN). When conﬁgured as a repeater, the base station passes data packets between remote stations based on the remote group status and a list of MAC (Media Access Control) addresses that the base station automatically builds. A single repeater uses a method called “store and forward” to receive data from the originating remote and to pass data to the destination remote. See Setting a Base to Repeater Mode

(Base Station Only)

, page 102 for more information. Two units can also be employed as a dual unit repeater

(back-to-back) conﬁguration that maximizes data throughput.

Some System Applications

You can build a wireless network from AWE units and various other components such as cables and antennas. The following section shows some simple examples of AWE applications.

Making a Simple Wireless Bridge

The simplest example of using a AWE 120-58 is a point-to-point wireless bridge that connects two wired network segments or LANs. Two AWE units are required: a base station and a remote unit.

Creating a Simple Wireless Network

You can create a point-to-multipoint wireless network by adding several remote units to a base station. A base station can support up to 1000 remotes, however, Wi-LAN recommends no more than 225 remotes per base station to ensure high levels of data throughput. See Determine the Number of Remotes for more information.

Some System Applications

Creating a Network with Cells

Cells or data nodes can be created with AWE units to maximize coverage, minimize interference, and increase data throughput. Directional antennas are mounted on a mast to divide cells into sectors.Each sector is connected to an antenna and a base station. Directional antennas increase signal gain within the sector and increase the distance possible between base stations and remotes. Center frequency, acquisition code and antenna polarization techniques are used to isolate sectors. The increase in data rate depends on the number of sectors. For example, the data rate of Cell 1 in the diagram below is 36 Mbps (12 Mbps x 3 sectors). Cells are distributed across a service area and can be linked to each other via a wireless link or a ﬁber optic cable.

Implementing a network with cells requires comprehensive network planning and site preparation. Please contact Wi-LAN for information about creating a network with cells.

Description

Using a Repeater Base

A base station can function as a repeater to enable wireless data communication around physical obstacles such as tall buildings or mountains. The repeater passes data around the obstacle to any remote in the same RF group. The single unit repeater slows data throughput due to the “store and forward” process where each packet is handled twice. A dual unit repeater does not slow data throughput.

4 Bench Test Units

In this section, you will perform the following tasks:

• Ensure that a basic RF link exists between a base station and a remote unit.

• Test the basic link with Link Monitor and adjust Tx power level.

• Perform some simple network tests.

Establishing a Basic RF Link

This test ensures that a basic RF link exists between a base station and a remote unit.

Important

The quality of your digital data transmission depends greatly on the quality of your RF

link. Always try to establish a high-quality RF link ﬁrst. A high-quality RF link will

result in high-quality data transmissions and a low BER. A low-quality RF link will result

in low-quality data transmissions and a high bit error rate (BER). Digital data can always

be sent across a high-quality RF link. If the RF link is of poor quality, data either cannot

be sent at all or will contain too many errors to be useful.

Tip: First conﬁgure one unit as a base station, and then use it to test all the remote units.

To establish a basic RF link

➧

1. Ensure that one unit is conﬁgured to a base station, select a center frequency and set the test minutes. See Configuring a Base Station , page 15.

2. Ensure that the other unit(s) are conﬁgured as remote units with the center frequency the same as the base station. See Configuring a Remote Unit , page 18.

3. Place the base station and a remote unit at least two meters apart with a clear line of sight between antennas. Point the antennas toward each other.

Installation

5 Install Units

This section provides some guidelines about installing units in the ﬁeld.

WARNING

All antennas must be professionally installed following accepted safety,

grounding, electrical, and civil engineering standards.

! CAUTION

Never operate a unit without an antenna, dummy load, or terminator

connected to the antenna port.

Operating a unit without an antenna, dummy load, or terminator connected

to the antenna port can permanently damage a unit.

• Install the units at locations identiﬁed in the network plan.

• Verify that there is no interference at the site by performing spectrum sweeps with a spectrum

analyzer. Perform sweeps at various times of the day (for example, 9AM, noon, and 3 PM are peak telephone trafﬁc times.) If there are problems, contact the network planner, who may need to change the system conﬁguration or design.

• If test equipment is available, sweep antennas and cables with the Site Master® communications test

set before securing antennas and cables to towers, while they are on the ground and easy to access. Sweeping helps to ensure that antennas and cables will operate as expected.

• Initially install equipment with ﬂexibility—do not tie down cables, antennas should be free to move,

allow some slack in cables, avoid drilling and do not seal connections.

• Align antennas*. (Two people are required, one at the base station and one at the remote unit. When

in the ﬁeld, you may require binoculars and 2-way radios to communicate.) When aligning antennas, adjust the orientation of the remote antenna while running a link monitor test between the remote and the base station. Adjust the antenna until you achieve the highest fade margin with no bit errors (BER = 0). See Performing Link Monitor Test (Normal Mode) , page 72 for instructions. Repeat the antenna alignment procedure for each remote.

• When antennas are aligned and cables are secured, sweep the antennas with the Site Master test set

a ﬁnal time before connecting to AWE.

• Perform diagnostic tests on the installed system. Compare ﬁeld results to bench test results using

ping, ftp, fade margins, etc. Document your results (these results will be very useful when troubleshooting and monitoring the system’s performance).

• When the system works as speciﬁed, lock down and weatherproof all equipment and connections.

* The antenna(s) used for this transmitter must be fixed-mounted on outdoor permanent structures with a separation distance

of at least 2 metres from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter.

6 Test Network

Point-to-Multipoint Installation

The procedure for installing a point-to-multipoint system is the same as the procedure for installing a pointto-point system. Treat each link in a point-to-multipoint system as a single, point-to-point wireless link.

Co-Location Installation

When you install a system with sectors and co-located base stations (see Creating a Network with Cells , page 5 for an example), you install and test sectors as if they were point-to-point systems; however, in this case you must ensure that individual sectors are not interfering with each other. Please contact Wi-LAN for information about planning and installing co-located units.

• Align and test the ﬁrst sector. Measure the fade margin and run the link monitor test. Document your results, then turn off the radio in the ﬁrst sector.

• Align and test the second sector. Measure the fade margin and run the link monitor test. Leave the link monitor test running in the second sector.

• Turn on the radio in the ﬁrst sector again and run the continuous transmit test. See Performing

Transmit and Receive Tests , page 75.

• Observe the BER and fade margin of the second sector radio. Look for changes to determine if the ﬁrst sector is interfering with the second sector.

• Repeat the tests for all sector/pair combinations.

6 Test Network

Run the link monitor test and other tests such as ping and ftp ﬁle transfers to verify network operation when the units are installed in the ﬁeld. See Performing Link Monitor Test (Normal Mode) , page 72.

Adding to a Network

Always add to your network one link or device at a time, working from a known base network. Measure and document changes to the system and changes in performance. For example, you can transfer ﬁles with ftp and measure the performance with LAN analyzer software. The key to a successful network is to proceed one step at a time and to understand your network!

You should set up a preventative maintenance schedule for your network. Wi-LAN recommends that the following preventative maintenance be performed at least semi-annually.

• Regularly run link monitor tests across the network and measure BER and fade margin. You can also test the network with ping, ftp and ﬁle transfers. Other resources are available on the Internet that can help you monitor the performance of your link.

• If you have SNMP application software, you can check unit operation from a remote location. See

Appendix D: SNMP , page 157 for more information.

If you have SNMP application software, you can check unit operation remotely. See Appendix D: SNMP , page 157 for more information.

You should periodically perform a physical inspection of each site.

• Check that antennas and cables are secure and have not become loose.

• Check for physical obstructions in the line-of-sight radio path, such as trees and buildings.

• Sweep antennas and cables to ensure that antennas and cables are intact and operating properly.

• Check that there are no water leaks in cabinets.

• Check weatherprooﬁng.

• Check for new sources of electromagnetic interference.

Block Disabled

Shows state of an individual ﬁlter. “Pass” allows packets to pass. “Block” stops packets from passing. “Disabled” enables you to make a particular ﬁlter inactive.

Two different IP ﬁlters are available: a packet ﬁlter, and an address ﬁlter. The IP packet ﬁlter determines which type of packets are allowed to pass through a unit. If the IP Packet Filter is OFF, the unit passes all packets. If the IP Packet Filter is ON, the unit passes only IP and ARP (Address Resolution Protocol) packets.

IP address ﬁlters are actually tables that contain lists of IP addresses. Data packets are either passed or blocked depending on whether the packet IP address is listed in the table, the setting of “Default IP Address Filtering” (pass or block), and the “State” setting of each ﬁlter.

Filter 1 blocks all packets containing a LAN-side IP address in the range 192.168.1.1 to 192.168.1.100 inclusive.

Filter 2 passes all packets containing a LAN-side IP address in the range 192.168.1.51 to 192.168.1.60. Note that this range partially overlaps the range of Filter 1, resulting in a conﬂict between ﬁlters. When a conﬂict occurs, the action speciﬁed by Default IP Address Filtering takes precedent, which is “Pass”. Therefore all packets with IP addresses that “overlap” will be passed.

All packets containing a LAN-side IP addresses not within either ﬁlter range are subject to the action speciﬁed by Default IP Address Filtering (passed).

The VLAN Registration Conﬁguration menu enables you to create, modify or delete entries in the VLAN Registration table as well as to specify this unit’s participation in the GARP VLAN Registration Protocol (GVRP).

The VLAN Registration table is used to deﬁne the sets of VLANs that can be reached (or alternatively cannot be reached) through individual ports of the unit. It is referenced by the following processes:

1. Ingress/Egress Filtering: If Ingress (Egress) ﬁltering is enabled, the Registration Table is referenced to

determine whether a packet is processed or ﬁltered on reception (transmission) based on the registration status of the VLAN associated with it on the inbound (outbound) por t.

2. Packet Forwarding on Hybrid Links: For hybrid links, the Registration Table determines for each

outbound packet whether VLAN tagging information is included with the packet, based on the destination VLAN for the packet.

3. GARP VLAN Registration Protocol (GVRP): If GVRP is enabled, the Registration Table is

referenced to determine the registration status for a particular VLAN on each port. GVRP is explained in more detail below.

MAC Address Filter Conﬁguration

The MAC Address Filter Conﬁguration menu enables you to create, modify or delete entries in the MAC Address Filter Table.

By creating a MAC address ﬁlter, you control whether this MAC address gains access to the network. The ﬁlter you specify contains a control element for each port which deﬁnes the access level of the MAC address for that port.

One example ﬁlter may be to block the relay of particular bridge protocol packets that use a known multicast address. By specifying “Filter” access for each port, you can restrict these packets to the local LAN(s) from which they originate.

Trafﬁc Class Conﬁguration

The Trafﬁc Class Conﬁguration menu enables you to specify the order in which outbound frames are transmitted based on packet priority.

Two “trafﬁc classes” are supported for each port, one class for “High” priority packets, another for “Low” priority packets. Outbound packets placed into the “High” trafﬁc class are transmitted before “Low” priority packets during the forwarding process.

Through the conﬁguration interface provided, you are able to assign different packet priorities to one of the trafﬁc classes supported. This process is further explained below.

Spanning Tree Conﬁguration

The Spanning Tree Conﬁguration menu enables you to specify parameters that deﬁne this unit’s role in the Spanning Tree Protocol.

The Spanning Tree Protocol is a link management protocol that enables path redundancy in a network while preventing the occurrence of broadcast loops. Participants in the Spanning Tree Protocol communicate with one another, together dynamically managing the network topology to ensure a loop-free conﬁguration.

Root MAC Address

This is the “root” bridge in the existing network (if this unit is a participant). The root bridge is responsible (among other things) for broadcasting notiﬁcation messages to all other participants to ensure a loop-free network conﬁguration

If this unit participates in the Spanning Tree Protocol, the conﬁgurable parameters mentioned above, Bridge Priority, Port Priority and Port Path Cost, are communicated to all other participants in the bridged network in a Spanning Tree Protocol packet. Similarly, all other participants broadcast their parameters to this unit. Based on this unit’s parameters and those received by other bridges, the network topology is created, possibly with some ports on some devices (maybe one on this unit) being disabled to prevent the occurrence of broadcast loops

If a change in topology is detected by any device, a notiﬁcation message is broadcasted and the network, if required, is re conﬁgured. This feature is particularly useful for critical links in which redundant paths exist. If one link should go down, a change in topology is detected and a second “backup” link is brought online.

Performing Link Monitor Test (Normal Mode)

The link monitor test can be run from either a base station or a remote unit that is set to Normal Mode. The test operates in parallel with the message stream, so it consumes some of the link’s total data capacity. You can control the ratio of test data to message data (and thereby control the amount of test data overhead) by setting the link monitor period. See Setting the Link Monitor Period , page 78 for more information.

Note: Link monitor test stays in effect even if you power cycle or reboot units, so you must turn it off using

Adjusting Throttling (Remote Station Only)

Throttling enables you to control the rate that data passes though a remote, so data throughput can be adjusted to make the data rate compatible with the rest of the system. Throttling restricts the ﬂow of data from air to wire or from wire to air. When throttling is enabled, the amount of data passed is equal to the throttling level times 64 kbps, to a maximum of 6.4 Mbps. Throttling applies to both down link and up link trafﬁc, so a throttle level of 1 means the unit will pass 64 kbps in each direction. A throttle level of 100 means that 100 x 64 kbps will be passed. When throttling is disabled, the unit uses the maximum available bandwidth. The default setting is to disable throttling.

RF Station Configuration

Setting Tx Power Automatically (Remote Station Only)

Output Power Control Mode can be used to adjust a remote unit’s Tx power automatically. Three different modes are available: off mode is selected to run Link Monitor in the usual manner (where Link Monitor tests the link and collects statistical information). Automatic Output Power mode tests the link (with Link Monitor) and automatically adjusts Tx power up or down based on measurements taken when the mode is selected. Dynamic Output Power mode runs Link Monitor in the background and periodically adjusts Tx power in response to the current radio conditions and environment. The amount of bandwidth (test overhead) used for all modes is set with Link Monitor Period . (See Setting the Link Monitor Period , page 78).

How Automatic Output Power Adjustment Works

Link Monitor tests a link by sending test packets and measuring the link’s performance (in terms of BER and power). The results of the test can be used to automatically adjust Tx power. Automatic power level adjustment is explained below.

The maximum Tx power output (factory-set power ceiling ) of a unit is set at factory and cannot be changed with conﬁguration menus (for more information see Viewing Unit Identification , page 35). A user-specified power ceiling or limit can be set by the user using the RF Station Conﬁguration

screen. The user-speciﬁed ceiling is the maximum Tx power level with which the

user allows the unit to operate.

Operating Tx Power Level

(Base Tx Power Level + Signal Margin)

Power Level

Base Tx PowerLevel

Noise Floor

The noise floor is the power level below which signal quality deteriorates rapidly due to random radio interference causing the link to not function properly. Base Tx Power level is the starting power level or "base" from which the adjustment is made. The operating Tx Power level is the sum of the base power level and the signal margin (fade margin)—the signal margin is added to the Tx base power level and moves with it. Both the base power level and the signal margin can be adjusted to reach the operating power level,

When a unit adjusts the power level, it begins at the base power level and runs Link Monitor. If no bit errors occur and the power level is satisfactory, the unit automatically drops the Tx power level by one dB and runs Link Monitor again. If no bit errors occur again and power level is adequate, it once again drops the Tx power

level by one dB and runs Link Monitor. This process repeats until a power level occurs where no bit errors occur and power level is lowest. This level is the minimum power level required for operation and is displayed

When the unit reaches this

Current Output Power Level Adjust

on the screen

level, Tx Power (seen on the Radio Module Conﬁguration screen) is automatically reset to the new level. (

Below this level, BER and power levels are unsatisfactory for data communication)

. If the intitial

base Tx power level is below the noise ﬂoor, a unit will automatically increment the power level by one dB until the BER and power level become satisfactory.

In short, two modes of automatic power level adjustment are available: automatic and dynamic.

Automatic Output Power mode: Power is monitored and automatically adjusted once when the automatic output power mode is activated. The resulting output power value is saved and Output Power Control Mode automatically returns to “off”.

Dynamic Output Power mode: Power is monitored and automatically adjusted periodically during regular operation. Some bandwidth for data is lost due to test packet overhead—the amount of overhead is determined by setting the Link Monitor Period (see Setting the Link Monitor Period , page 78). Dynamic Output Power mode is not recommended in co-location situations.

Note: A unit will adjust the power output to compensate for noise problems, however if the noise ﬂoor is

too high the unit will not be able to establish an RF link. In this case, an RF spectrum analysis should be performed to determine the cause of the problem.

Tx Power Adjust on the Radio Module Conﬁguration screen is used to set the initial or base Tx power level. After the level is set automatically, this value is automatically reset by the unit. The reset value can be read by viewing Current Output Power Level Adjust on the RF Station Conﬁguration screen, or by viewing Tx Power Level Adjust on the Radio Module Conﬁguration screen.
