Hopper Plus 120-24 Installation & Configuration Guide

Description

Features

The Hopper Plus 120-24 is a wireless Ethernet bridge that provides high-speed, wireless connectivity at a fraction of the cost of wired solutions. It operates over the license-exempt 2.4 – 2.48350 GHz ISM radio band and has a maximum raw wireless data rate of 12.0 Mbps.

• Provides wireless connectivity at speeds up to eight times faster than regular T1 lines, making the Hopper

Plus 120-24 ideal for providing high-speed Internet access or for wirelessly extending existing communications infrastructures.

• Supports point-to-point, point-to-multipoint, and multipoint-to-multipoint networks. Contentionless polling

ensures efﬁcient access to remote data networks.

• Is self-contained and easy to use. Simply connect a Hopper Plus 120-24 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 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.

About Spread Spectrum

The FCC allocates three license-free frequency bands (called the ISM bands) to a radio technique known as spread spectrum communication. The bands are located at 900MHz, 2.4 GHz, and 5.7 GHz (shown in the following illustration). The Hopper Plus 120-24 operates with spread spectrum technology over the

2.4 – 2.4835 GHz band.

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.

• Fast throughput: A wide bandwidth means fast data throughput.

• 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 (a Hopper Plus can only talk to another Hopper Plus). Data is transmitted at irregular time intervals. Upon request, Wi-LAN can assign a customer a data packet security code so that a customer can only receive transmissions from another Hopper Plus with the same code.

• 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, transmitter power is limited, and a non-standard antenna connector is used.

About Hopper Plus Units

Hopper Plus units can function as base stations, remote units or repeater bases.

Base Station: At least 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 16 for information about setting up a base station.

Hopper Plus 120-24 Installation & Configuration 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. Because 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 19 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. The repeater uses a method called "store and forward" to receive data from the orignating remote and to pass data to the destination remote. See Setting a Base to Repeater Mode (Base

Station Only) , page 72 for more information.

Some System Applications

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

Making a Simple Wireless Bridge

The simplest example of using a Hopper Plus 120-24 is a point-to-point wireless bridge that connects two wired network segments or LANs. Two Hopper Plus 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 esnure high levels of data throughput. See Determine the Number of Remotes , page 107 for more information.

Some System Applications

Creating a Network with Cells

Cells or data nodes can be created with Hopper Plus units to maxmimize 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 37.5 Mbps (12 Mbps x 3 sectors x 75%; 25% is overhead). Cells are distributed across a service area and can be linked to each other via a wireless link or a ﬁber optic cable.

Bench Test Units

Note: At this time you may want ﬁnish conﬁguring the unit according to the network plan. See Conﬁguration,

page 31 for instructions about viewing and changing various settings.

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 ability of the link to carry test data

• Perform a simple network test

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 16.

2. Ensure that the other unit(s) are conﬁgured as remote units and with the center frequency the same as the base station. See Conﬁguring a Remote Unit, page 19.

3. Place the base station and a remote unit at least twenty meters apart with a clear line of sight between antennas. For directional antennas, point antennas toward each other. For a dipole antenna, orient the antenna vertically.

4. Power up the base station. The green POWER LED is ON. The AIR LED of the base unit is red. This AIR LED color indicates that the unit is transmitting data but is not receiving a response. (The reason is that the remote is powered off.)

5. Power up the remote unit. The green POWER LED is ON. The AIR LED of the remote unit turns orange and the AIR LED of the base station also turns orange as both units send and receive data from each other. Orange is the normal AIR LED color.

The color of the AIR LED during this step indicates the following conditions.

Orange (both stations) Units are continuously sending and receiving sync packets

Red (base station) Stations are conﬁgured incorrectly, and the base station is

transmitting without receiving acknowledgment

Green (remote station) Stations are conﬁgured incorrectly, and the remote station is

receiving packets to which it cannot respond

Off Nothing is being received (by the remote) or transmitted (from the

base)

Note: If antennas are placed too close together (< 20 m), the strong transmit signal can saturate the

receiving unit. Fine-tune antennas by changing antenna orientations until the AIR LED is orange.

Next, you will test the link’s basic ability to carry data.

22 Hopper Plus 120-24 Installation & Configuration Guide

Bench Test Units

Testing a Basic RF Link

When both the base station and remote unit can receive and transmit data to each another (indicated by orange AIR LEDs on both units), a basic RF link is established. You can now test the link with Link Monitor. Link Monitor tests a link by sending and receiving test data over a link, in both directions, at the same time. For information about testing a link in the receive or transmit direction only, see Performing Link Monitor Test

(Normal Mode), page 52.

To test the RF link

26 Hopper Plus 120-24 Installation & Configuration Guide

Install Units

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

• Install the units at locations identiﬁed in the network plan. Some units will simply sit on a table or desk and do not require any special antenna work. Other units must be installed inside communication cabinets or racks and will require professional antenna installation.

WARNING

Outdoor antennas must be professionally installed following accepted safety, grounding,

electrical, and civil engineering standards. An antenna (indoor or outdoor) must be

connected to the ANTENNA port of a unit before a unit is powered up to avoid

damaging the unit.

• 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.

Install Units

• 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 the RSSI Test, page 57 and Performing Link Monitor Test (Normal Mode), page 52 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 Hopper Plus.

• 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 in the network plan, lock down and weatherproof all equipment and connnections.

Point-to-Multipoint Installation

The procedure for installing a point-to-mulitpoint 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.

DEC 2000 Rev 02

27

Installation

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.

• 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 tranmit test. See Performing Transmit

and Receive Tests, page 55.

• 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.

Test Network

Run the link monitor test, transmit test and network tests such as ping and ftp ﬁle transfers to verify operation when the units are installed in the ﬁeld. See Performing Link Monitor Test (Normal Mode), page 52.

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 a tool such as NetXray®. The key to a successful network is to proceed one step at a time and to understand your network!

Preventative Maintenance and Monitoring

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, for example see www.globalcast.se.

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

Appendix D: SNMP, page 133 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.

IP Filter Configuration

IP Filter Conﬁguration

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 containing sets of IP addresses. When IP address ﬁltering is enabled, all IP packet are sorted according to the following conditions:

1. If the source IP address is contained in one of the IP address lists, IP packets coming from the wire will

be forwarded to the air. If not, IP packets are dropped.

2. If the destination IP address is contained in one of the IP address lists, IP packets coming from the air

will be forwarded to the wire. If not, IP packets are dropped.

Each IP address ﬁlter is deﬁned by a range and base value. IP address ﬁltering improves system security and helps manage data throughput.

• To perform the Normal Mode (Link Monitor) test you need to connect a PC to either the base

station or a remote unit.

• To perform the Transmit Test or Receive Test you need at least one base station with PC, a remote

station with PC, and an RF link between units. See Establishing a Basic RF Link, page 21 for instructions about establishing an RF link.

• To perform the RSSI test you need a PC for the unit that will transmit. The receiving unit does not

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 59 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

the Link Monitor Period (0 = OFF) setting.

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 128 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 128 kbps in each direction. A throttle level of 50 means that 50 x 128 kbps will be passed. When throttling is disabled, the unit uses the maximum available bandwidth. The default setting is to disable throttling.

Radio Module Conﬁguration

The Radio Module Conﬁguration menu is used to change several key parameters, including station type, station rank and security passwords. Because these settings can affect service, they are changed in three progessive stages: new, current, and ﬂash. (New and current are for temporary storage, while ﬂash is for long-term storage.) The general procedure for changing settings with the Radio Module Conﬁguration menu follows.

1. View the current Radio Module Conﬁguration menu. See Viewing the Radio Module Conﬁguration, page 63.

2. Select Config Test Minutes. To begin, enter a time of 15–20 minutes. See Setting Conﬁg Test

Minutes, page 65.

3. Select a parameter and, if necessary, change the value in the "New" column.

4. After making changes, select Reboot New RF Configuration and press Enter. The unit reboots

and the "New" settings become the "Current" settings of the unit. See Rebooting and Saving RF Module

Conﬁgurations, page 79.

5. If the unit operates as expected, you can save the current settings to "Flash". See Rebooting and Saving

RF Module Conﬁgurations, page 79.

If current settings do not operate as expected, do not save them to "Flash". Change the current settings

or wait for the Config Test Minutes time period to expire. At expiry, the unit will automatically reboot and revert to the last-saved ﬂash memory settings. See Rebooting and Saving RF Module

Setting the Station Rank

Station Rank is deﬁned two different ways, which depend on the station type: For a base station, rank is the total number of remotes that a base will poll. For a remote unit, rank is a unique polling ID number that identiﬁes a remote to a base station.

When it polls remotes, the base station begins polling at the remote with rank number 1, then proceeds to the remote with rank number 2, then goes to the remote with rank number 3, and so on. The base continues polling remotes until it reaches the remote with the highest rank number. The base then repeats the polling cycle.

Note: Dynamic polling gives you some control over the polling process. See Setting Dynamic Polling Level (Base

An acquisition code is a unique code contained within the preamble of a transmitted message. Units search the air for messages that begin with a particular acquisition code. Messages without the correct code are treated as interference and are rejected by a unit. Messages with the correct code are accepted and processed. Acquisition codes serve to isolate units from each other, especially when several units operate in close proximity or at the same frequency in a multiple-sector or multi-cell environment.

When repeater mode is enabled at a base station, the base acts as a repeater in addition to performing its normal base station functions. As a repeater, the base station receives incoming messages from remotes, stores them and broadcasts them to all remotes within RF range. Remotes belonging to the same RF group (with the same RF Group number) can communicate via the repeater. (See Setting Remote Unit RF Group, page 76 for information about RF groups.) The following diagram expains the process.

When repeater mode is disabled (Repeater Mode = off), the base station functions normally (it polls remotes and links the various segments of the network). By deﬁnition, Repeater Mode does not apply to units of RF Group = 0.

Setting System Symmetry Type (Base Station Only)

System symmetry type ﬁxes the priority of the base unit when it polls remotes. The default "asymmetric" setting alots the base one time slot for each time a remote is polled—this setting is useful when the base is the access point to a large network. The "symmetric" setting alots the base one time slot per polling cycle. A symmetric system gives the base station the same polling priority as a remote unit.

Radio Module Configuration

Setting Dynamic Polling Level (Base Station Only)

Dynamic polling improves system performance by reducing overhead due to idle remote units. A base station automatically learns which remote stations are active and which are idle. The base station waits a brief time period for a remote to respond to a poll. If the remote doesn’t respond within the time period, the base considers the remote to be idle. (This process is called dynamic time allocation or DTA.) Idle remote units are ignored by the base station for the number of polling rounds entered in the Dynamic Polling Level ﬁeld. The higher the dynamic polling level, the more efﬁcient the throughput and the longer it takes to move a subscriber from an inactive state to an active state. Dynamic Polling improves system performance whenever there is more than one remote. When there are a large number of remotes system performance improves signiﬁcantly.

Note: Polling level is set only at the base station.

Setting Remote Unit RF Group

The RF Group setting enables you to determine which units in a system can communicate with each other. For example, in a system consisting of a base station and associated remotes, you can: 1) assign units to different groups so that only members of the same group can communicate with each other and the base (an open system); 2) isolate remotes so they cannot talk to other remotes, but can talk only to the base (a closed system); and 3) assign remote units to groups and conﬁgure the base station as a repeater (a closed system). These conﬁgurations are explained below.

Remote units with the same RF group number (RF Group = 1– 63) can communicate directly with each other and with the base station (if there is a line-of-sight RF path between units and base station Repeater Mode = off.) An example is a company where the Human Resources department needs direct access to the Payroll department, but the two departments must be isolated from other departments. Since HR and Payroll are in the same RF group 14, they can talk directly to each other, but they cannot talk directly to other groups such as R&D, which belongs to RF Group 20.

Example 1: Open System

Repeater Mode = off

Base

Remote

RF Group = 20

R&D

Remote

RF Group = 14

Human Resources

RF Group = 14

Payroll

RF Group = n

n = 1 – 63

Remote units conﬁgured as RF Group = 0 are independent, closed units. Closed units cannot talk directly to each other, they can only talk directly to the base station. This setup acts to isolate remote units and the associated LANs from each other. Example 2 shows a situation where independent companies are connected wirelessly to a single base station and communication between the companies is prevented.

Radio Module Configuration

A repeater is used to bypass obstacles that block the RF path (for example, a mountain). When a base station is set to repeater mode (Repeater Mode = on), it can pass data from remotes in an RF group to other remotes in the same group. A system with a repeater is a closed system. Example 3 shows a repeater with four remotes. All the remotes are in the same RF Group 4, so they can talk to each other via the repeater base.

Rebooting and Saving RF Module Conﬁgurations

Because changes to Radio Module Conﬁguration settings can affect service in a wireless system, changes are made in three progessive stages: new, current, and ﬂash.

New Intended conﬁguration changes. Temporary memory storage.

Current Conﬁguration actually running on the unit. Temporary memory storage.

Flash Conﬁguration stored in FLASH memory. Long-term memory storage.

A reboot of a unit is required to save New settings as Current settings. If Current settings are valid (and do not disrupt the system), they can be saved to Flash memory. If the changes disrupt the system, the original conﬁguration will be restored automatically when the Conﬁg Test Minutes period expires.
