Introduction
AIRAYA WirelessGRID-300 series wireless bridges have been designed to
provide transparent, high-speed data communications between two or
more locations.
The WirelessGRID-300 utilizes detachable antennas and is an outdoor
radio product, with external antenna connections. The product requires
installation by a certified professional installer, only.
WirelessGRID-300 firmware will not allow the end user to change or
modify the country code settings of this product. The availability of
specific channels and/or operational frequency bands are country
dependent and are programmed in firmware to match the intended
destination, by AIRAYA Corp. factory personnel only. The US Country
Code setting will only allow operation in the 5.725-5.850 GHz band for 20
& 40 MHz wide channels. The PS Country Code will allow operation in the
5.725-5.850 GHz band for 20 & 40 MHz wide channels, while also
allowing the use of 4.940-4.990 GHz band with bandwidths of 5, 10, 15 &
20 MHz wide channels.
This solution offers proven, fast, reliable, and secure wireless connectivity
with considerable cost savings compared to wired alternatives. Utilizing

Hardware Description
Ethernet Compatibility
WirelessGRID-300 wireless bridges can be attached directly to 10BASE-
100/1000 BASE-TX (twisted-pair) Ethernet LAN segments. These
segments must conform to the IEEE 802.3 specification.
Each WirelessGRID-300 bridge functions as an Ethernet node and
performs layer 2 bridging by moving packets from a network in one
building to a network in another building.
Radio Characteristics
WirelessGRID-300 bridges utilizes a radio modulation technique known as
Orthogonal Frequency Division Multiplexing (OFDM) capable of operating
in the4.940-4.990 & 5.725-5.850 GHz bands. Data is transmitted over a
radio channel at signaling rates up to 300 Mbps in 5.8 GHz band and 130
Mbps in the 4.9 GHz band.
Antenna Options for 5 GHz Operation
The outdoor version of the WirelessGRID-300 bridge uses FCC certified
antennas to achieve a maximum operating range up to 30 miles under FCC
rules in the 5.8 GHz band. When using antenna in the 4.9 GHz band, an
antenna gain greater than 26 dBi, will require the user to reduce the radio
output power by the amount of gain abover 26 dBi.
This device has been designed to operate with the antennas listed
below in the 5.8 GHz band only, and having a maximum gain of 29 dB.
Antennas not included in this list or having a gain greater than 29 dB
are strictly prohibited for use with this device. The required antenna
impedance is 50 ohms.
To reduce potential radio interference to other users, the antenna type and its
gain should be so chosen that the equivalent isotropically radiated power
(e.i.r.p.) is not more than that permitted for successful communication.

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.

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.

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.

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.

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.

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.

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.

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.
