Appendix C: Testing the WLAN Handsets 2210/2211
• Detect dBm coverage – Press FCN to toggle to the Site Survey function that shows the
top four APs. Walk the perimeter of the site. The two-line display on the wireless handset
shows the top four APs that the wireless handset can contact. The information is shown in
code as follows.
— XXX1 through XXX4 are the last four digits of the MAC address of the APs. The
primary AP (the AP that had the strongest signal to this wireless handset) appears 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 should have a reading stronger than –70 dBm in all areas.
• Detect overlap or conflicts – Press FCN 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 MAC address of the APs.
— 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 at least 10
dBm stronger than the other two APs to prevent channel conflicts.
• Confirm supported data rates – Press FCN to toggle to the Detl function which shows
details of the specific AP. Use this information to confirm signal strength and supported
data rates.
— # is the number (1 – 4) of the AP
— Full MAC is the MAC address of the AP
