•
XXX1 through XXX4 are the last four digits of the access points’ MAC address. The
primary access point (the access point which had the strongest signal to this Wireless
Telephone) displays first, followed by the three access points with the next strongest
signals.
•
YY is the power level in dBm at which this Wireless Telephone heard the associated access
point. Although shown as a positive number, YY represents negative dBm and lower
numbers represent stronger signals. For example, a displayed value of 40 indicates 40dBm,
and is therefore a stronger signal then a display of 50 (which indicates –50dBm). At least
one access point’s reading should be stronger than -70 dBm in all areas.
Note any areas that have inadequate dBm readings.
Detect overlap or conflicts
Press
FCN
to toggle to the Site Survey function that shows the channel number of the access points.
Use this information to detect overlaps or conflicts in access point signaling.

•
XXX1 through XXX4 are the last four digits of the access points’ MAC address.
•
ZZ is the channel number that the access point is using.
Note any areas that have access points that are in contention for the same channel.
It is preferable that no overlaps exist anywhere in your facility. If that is not possible, then any location
that shares two APs with the same channel should also show at least 2 APs with stronger signals, that
do not conflict.
Confirm Supported Data Rates
Press
FCN
to toggle to the Detail function. Use this information to confirm signal strength and
supported data rates.

#: the number (1-4) of the AP.
•
Full MAC: the MAC address of the AP
•
dB: the signal strength of the AP
•
Ch: the channel of the AP

1b2b5b11b is an example of the data rates that may be displayed.
Walk around the site to determine supported data rates, one AP at a time. In any location you may use
the right arrow key to display the second best AP, arrow again to the third best, and so on to the fourth
best. The left arrow key steps you back to the first best.
