2.5 Deploying the SMC2586W-G
After the settings have been configured, deploy the SMC2586W-G to the
field application environment. Connect the SMC2586W-G to an Ethernet
LAN through an Ethernet switch/hub.
If external high-gain directional antennas are needed, it may be difficult to
align the antennas. Here are some suggestions for antenna alignment.
To adjust the alignments of a pair of SMC high-gain antennas:
1. Connect each SMC2586W-G to a computer via Ethernet.
2. Configure the date rate of each SMC2586W-G to the lowest value, 1Mbps.
3. Fix the alignment of the antenna on one side.
4. Adjust the alignment of the antenna on the 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 the best response
time.
6. Increase the data rate of each SMC2586W-G simultaneously until an
optimal workable data rate is reached. You may not be able to use the
highest data rate, 54Mbps, be-cause of the distance and the gain of the
antennas. Fig. 14 illustrates the idea.
