Airaya – Fast and affordable outdoor wireless bridges
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 Bridge List for the MAC address of the bridge B,
and bridge B should have an entry in its WirelessGRID 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.
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.
Step 4a. Check throughput of WirelessGRID link (optional)
To check the throughput of a WirelessGRID 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 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 link.
AIRAYA’s internal bench test results can be found at the following web address:
http://www.airaya.com/products/wirelessgrid_testdata.html
NOTE
If you use 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 10 Mbps
Ethernet device. AIRAYA recommends 100 Mbps Ethernet switches or routers to maximize
throughput. Throughput tests will not work if Step 4 above has not been finished
successfully.
