2.5. Deploying the SMC2582W-B
After the settings have been configured, deploy the SMC2582W-B to the field application environ-
ment. Connect the SMC2582W-B to an Ethernet LAN through an Ethernet switch/hub.
If external high-gain directional antennas are used for a long-range wireless bridging application, it
may be difficult to align the antennas. Here is a suggestion for antenna alignment.
To adjust the alignments of a pair of SMC high-gain antennas:
1. Connect each SMC2582W-B to a computer via Ethernet.
2. Configure the date rate of each SMC2582W-B 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
information 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 SMC2582W-B simultaneously until a maximal workable
data rate is reached.You may not be able to use the highest data rate, 11Mbps,
because of the distance and the gain of the antennas.
Fig. 14 illustrates the idea.
