WLAN Handsets 2210/2211 configuration
• XXX1 through XXX4 are the last four digits of the AP's' MAC address.
The primary AP (the AP which had the strongest signal to this wireless
handset) displays first, followed by the three APs with the next strongest
signals.
• YY is the power level in dBm at which this wireless handset heard the
associated AP. Although shown as a positive number, YY represents
negative dBm. Lower numbers represent stronger signals.
For example, a displayed value of 40 indicates –40dBm, and is a stronger
signal than a display of 50 (which indicates –50dBm). At least one AP's
reading should be stronger than –70 dBm in all areas.
Note any areas that have inadequate dBm readings.

Press to toggle to the Chnl function that shows the channel number of
the Aps. Use this information to detect overlaps or conflicts in AP signaling.

• XXX1 through XXX4 are the last four digits of the AP's' MAC address.
• ZZ is the channel number that the AP is using.
Make note of any areas that have APs that are in contention for the same
channel.
It is preferable that no overlaps exist anywhere in the site. If the Site Survey
mode indicates two APs using the same channel, then at least one other AP
must be indicated must be indicated at least 10 dBm stronger than the other
two APs to prevent channel conflicts.
