This screen provides the following data: Bridge Status NOTE Tip: To allow WirelessGRID-300 bridges to monitor their own signal strength and packet error rates and dynamically adjust data rates, you can set Data Rate on the Radio Settings tab to "Best". This will allow the bridge to monitor signal strength on a packet-by-packet basis, adjusting data rate accordingly. If signal strength is not optimum, the radio will adapt and change to a lower modulation, which in turn lowers the radio data rate, but provides a higher effective TCP/IP data rate by increasing radio receiver sensitivity and reducing the packet error rate. This adaptive data rate ability provides for better overall quality and reliability of the link. Tip: When running time sensitive applications such as VoIP and/or VideoIP cameras, setting bridges to specific data rates reduces latency and improves performance on these systems.

- 36 - Airaya WirelessGRID-300 Backhaul Appendix A – Bench Test Procedure This WirelessGRID-300 bench test guide is designed to provide a new AIRAYA installer with insight and understanding of how to setup, test and verify the functionality of a WirelessGRID-300 link before performing a field installation. Utilities for testing network communication, configuring bridges, aligning antennas, and measuring throughput are discussed. Answers to common questions and troubleshooting tips are noted throughout the document for your convenience. While performing a bench test, antenna alignment is not critical as antennas are close together and the signal strength (RSSi) utilities will always show a strong signal. As in all field installations, bench tests should be performed with antennas correctly polarized, either vertically or horizontally, and pointing at each other, at a distance of no less than 15 feet apart. To obtain optimal throughput and link reliability, signal strength readings should be above 18 for all bench tests. Very high signal strength values (RSSi above 50) are common in bench tests and will not damage radios; however, measured TCP/IP throughput results may be lower. Bench test Procedure Step 1. Setup a wired Ethernet network between test stations 1. Configure 2 test stations so that their network IP addresses are in the same range and can communicate with each other via Ethernet. If you are not familiar with IP addresses, please contact AIRAYA for the name of a qualified network installer in your area. 2. Verify your test network setup by using an Ethernet crossover cable directly connected between the two test stations, or by connecting the 2 stations using a switch, hub or router using straight-through Ethernet cables. To verify your wired network setup is working properly, run a continuous ping between test stations A and B. To do this, open a DOS or CMD window on test station A, then type the following at the command prompt: ping 192.168.1.72 –t and on station B, type ping 192.168.1.73 -t Note: -t runs a continuous ping.
Airaya - 37 - Airaya Proven, Fast and Affordable Outdoor Wireless Bridges If you receive ping responses from both test stations, the network IP configuration and physical wiring is working properly between the 2 test stations using Ethernet. If you cannot ping both test stations, check your Ethernet cable connections and test station network settings to verify they are configured properly. When ping works properly with wired test stations, go to Step 2. Step 2. Setup wired Ethernet network connections to bridges Connect directly using straight-thru cables, or through network switches or routers using straight-thru Ethernet cables. Example IP Configuration of test stations and outdoor bridges with default configuration parameters: 1. Start a continuous ping from test Station A to bridge end point A. To start a continuous ping using the factory default IP settings of the bridge, type the following into a DOS or CMD window on test station A: NOTE WirelessGRID products shipped as complete kits have one bridge factory-configured with IP address 192.168.1.70, and one bridge factory-configured with IP address 192.168.1.71. Both bridges have a default subnet mask of 255.255.255.0 1000 Mbps full duplex (gigabit) ports are best from connecting bridges to wired Ethernet networks. NOTE If ping does not work between 2 wired test stations, it will not work between 2 test stations connected by a WirelessGRID link.
- 38 - Airaya WirelessGRID-300 Backhaul Ping 192.168.1.70 –t (leave this ping window running so you can see ping results easily) 2. If there is no response, try IP address 192.168.1.71, or cycle the power on bridge end point A. After ~45 seconds, you should see ping responses from 192.168.1.70 (bridge A). If you see ping responses on test station A, you have an IP network connection between test station A and bridge A. If you can ping bridge A, you can open the HTTP configuration utility and network management system (NMS) using a web browser. You will not be able to ping across the link to bridge B until WirelessGRID-300 bridge list authorization entries are made in both bridges. (See step 3) 3. Setup the Ethernet network connection between bridge B and test station B using the same procedure described above, then verify that the test station B to bridge B setup is correct. After verifying that both bridges and their respective test stations can communicate via Ethernet, go to step 3. Step 3. Setup bridge software configuration for bridge After verifying that both bridges and their respective test stations can communicate via Ethernet, you will need to setup and verify bridge configuration so they will be able to communicate over the radio link. The configuration given here will be a minimal configuration for test purposes; for more detailed configuration information, please refer to the product manual. 1. On each test station, open an http session by entering the bridge IP address into the address field of your web browser. The correct format is: http://192.168.1.70, or whatever the bridge’s IP address has been set to. Note Check that the Ethernet link light is on at test station A if connected directly to bridge A with straight-thru cable, or on the switch/router port that bridge A is plugged into if connected with a straight-though Ethernet cable. If the Ethernet link light is on and you cannot ping bridge A, then re-check IP address and NOTE Factory default administrative User Name and Password are Airaya with an uppercase A As a security measure, the WirelessGRID http configuration utility and network management systems (NMS) will timeout if left open with no activity for 3 or more minutes. You will need to re-login to again access the utility.
Airaya - 39 - Airaya Proven, Fast and Affordable Outdoor Wireless Bridges 2. Login using the default Administrator name and password. Each test station should now be displaying the “Current Settings” screen. 3. Record the IP address and MAC address of each bridge. You can also enter a Unique Name under the Admin Setup tab to help in identifying bridges. It is common to use this field to enter 32-character location identifiers. Bridge IP Address MAC Address Unique Name A B 4. Under WirelessGRID-300 Bridge List, on bridge A, click “Add” and enter bridge B’s MAC address in the “Bridge MAC Address” box, using the xx:xx:xx:xx:xx:xx format. Click “Add New.” 5. On bridge B, use the same procedure above to add bridge A’s MAC address. 6. On the “Data Encryption” tab, make sure “Encryption Type” is disabled. 7. On each bridge, click on the “Reboot” button on either the Network Settings or Radio Settings tab to enable new WirelessGRID-300 Bridge List settings. 8. On each bridge, reopen the http interface and verify that entries were correctly saved by reviewing the “Current Settings” screen. After verifying that both bridges have the proper WirelessGRID-300 Bridge List settings, go to step 4. Step 4. Test network connectivity across a WirelessGRID-300 link After verifying that both bridges and their respective test stations can communicate via Ethernet, and confirming new WirelessGRID-300 bridge list entries were saved, the following ping tests should be done. To verify network connectivity across a WirelessGRID-300 link, you should use test station A to do the following: Ping 192.168.1.70 -t to ping bridge A Ping 192.168.1.71 -t to ping bridge B across the wireless radio link NOTE After rebooting bridges, the radio link should be established within one minute. If TPC and DFS are enabled, this process may take up to two minutes. Test Station A Test Station BBridge ABridge B
- 40 - Airaya WirelessGRID-300 Backhaul Ping 192.168.1.72 -t to ping test station B across the wireless link If all ping tests are successful, then you have a properly configured WirelessGRID-300 link. Go to Step 5. Troubleshooting tips for pinging across a link: If you do not get a ping across the two end points from test station A to test station B; You may have a power problem - Verify that each bridge is connected to a power source with the proper input voltage. You may have an Ethernet network cable problem at one end - Verify all physical connections. You should have an Ethernet link light on the switch, router, or computer connected to each bridge. You may have an http configuration error - Verify the configurations of both bridges using the http NMS. Bridge A should have an entry in its WirelessGRID-300 Bridge List for the MAC address of the bridge B, and bridge B should have an entry in its WirelessGRID-300 Bridge List for the MAC address of the bridge A - without correct MAC addresses (bridge authorization) in each side of the link, the bridges will not communicate or let traffic pass. Step 4a. Check throughput of WirelessGRID-300 link (optional) To check the throughput of a WirelessGRID-300 link, use an FTP program or some other type of throughput measuring utility to check the speed of your link. If you don’t know what program to use to test link throughput, AIRAYA can provide you with a traffic generating program and shareware throughput monitoring utility at no charge. A link to NOTE When doing a Multipoint bench test, it is best to setup the base station as bridge A, and the first subscriber unit as bridge B using the procedure in Step 3. To test additional subscriber units, use this procedure for each new subscriber unit, repeating the ping test for bridge B one at a time. Use different IP addresses for each new subscriber units. (E.g. Ping 192.168.1.74 -t for subscriber two, and so on) This will simplify diagnostics. Once all subscriber units (SU) respond to this test and you have verified that each subscriber has a different IP address, you can power up all SU’s and each one should be ping-able.

Airaya - 41 - Airaya Proven, Fast and Affordable Outdoor Wireless Bridges these utilities can be found on the main page of the AIRAYA support section of website. http://www.airaya.com/products/productdb/_product_support.asp If you are planning to do meaningful throughput tests, you will need a minimum of 2 test stations with at least 1.6GHz processors and Windows XP, 2000, or the Linux operating system. Windows 95, 98, ME TCP/IP stacks limit TCP throughput and cannot be used to accurately test throughput on an AIRAYA WirelessGRID-300 link. AIRAYA’s internal bench test results can be found at the following web address: http://www.airaya.com/products/WirelessGRID-300_testdata.html NOTE If you use 100/10 Mbps Ethernet to communicate with a WirelessGRID bridge, you will not get maximum throughput, and packet errors may occur between the bridge and your 100/10 Mbps Ethernet device. AIRAYA recommends 1000 Mbps Ethernet switches or routers to maximize throughput. Throughput tests will not work if Step 4 above has not been finished successfully.
- 42 - Airaya WirelessGRID-300 Backhaul Step 5. Field deployment of WirelessGRID-300 bridges It is a good idea for you to become familiar with the product before installing it for the first time. AIRAYA recommends you perform a bench test before deploying any units to the field. The bench test and verification process can also be performed in the field, but it is generally much easier to configure the units on the bench before setting them up in the field. Changes in field-deployed bridges include but are not limited to the following: 1. IP Addresses to match your network 2. Change the administrative user name and password to prevent un-authorized access the administrative interfaces 3. Location-specific unique names entries to help in identifying units in the field 4. Encryption enabled if you want your data encrypted as it travels across your new WirelessGRID-300 system.
