9-2 Certifying MH110/MH120 Mobile Handsets
MH110/MH120 IP Wireless Telephone Setup and Administration Guide - Revision 1
Site Survey Mode
Signal strength in the covered area is tested by performing a Site
Survey. Put a Mobile Handset in Site Survey Mode
Walk the entire coverage area while viewing the display. The FCN key
toggles between the three coverage modes:
• Detect dBm coverage
• Detect Overlap or Conflicts
• Confirm Supported Data Rates
The Mobile Handset will remain in Site Survey mode until it is powered
off. When testing is complete, press Power Off to turn off the Mobile
Handset. Numbers racing across the Mobile Handset display indicate AP
information is being obtained. A Waiting message indicates the system
is not configured properly and the Mobile Handset cannot find any APs.
Detect dBm coverage
As you walk the perimeter, the two-line display will show the top four
access points that the Mobile Handset can contact in a code as
illustrated below.
Figure 9-1 Detect dBm coverage
• 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 Mobile Handset) displays first, followed by the
three access points with the next strongest signals.
• YY is the power level in dBm at which this Mobile Handset heard the
associated access point. Although shown as a positive number, YY
represents negative dBm and lower numbers represent stronger
signals.
