Gain Setting for 802.11b/g Channels
The default gain for each
802.11b/g
channel is set to 0dB. MA 850A1 enables the authorized
user (
admin
level) to adjust the gain for every channel to counteract changes in the
environment.
For example, you may want to reduce the coverage area of a channel to prevent interference.
Or, the output of an AP with a low power (<20dBm) can be increased using the gain value to a
maximum level of 20dBm
.
