2.5 Deploying the AP After the settings have been configured, deploy the AP to the field application environ-
ment. Connect the AP to an Ethernet LAN through an Ethernet switch/hub.
If you are configuring a pair of the APs for a dynamic or static bridging application and
external high-gain directional antennas are used, it’s difficult to adjust alignments of the
antennas when the pair of devices is distance away.
To adjust the alignments of a pair of bridges’ directional antennas:
1. Connect each bridge to a computer via Ethernet.
2. Configure the date rate of each bridge to the lowest value, 1Mbps.
3. Fix the alignment of the antenna on one side.
4. Adjust the alignment of the antenna on other side by using response time informa-
tion obtained from PINGing (run PING.exe) the “fixed-side” computer.
5. Fine-tune the alignment of the antenna until you get a best response time.
6. Increase the data rate of each bridge simultaneously until a maximal workable
data rate is reached. You may not be able to use the highest data rate, 54Mbps,
because of the distance and the gain of the antennas.

TIP: When doing dynamic bridging, configure Bridge 1 to be in AP Client mode and con-
figure Bridge 2 to be in AP/Bridge mode.
TIP: If you are doing static bridging, you can make use of the Antenna Alignment As-
sistance feature to help you align the directional antennas.
