The handset’s site survey mode is not a replacement for a
professional site analysis and should be used only for testing,
limited site validation, and troubleshooting.
The handset’s site survey mode does not include functionality to
allow for analysis or troubleshooting of 802.11n specific WLAN
features.
1. Referring to Chapter 8 Diagnostic Tools, section Run Site Survey,
put a handset into Site Survey in the Any / Smry ESSID mode. Walk
throughout the site checking for any expected APs or other
ESSIDs.
2. Then, walk the site again, in MyID / Smry ESSID mode, this time
checking that every location has adequate coverage and has good
channel allocation.
There should be at least one AP stronger than -the minimum
specified in the following tables.
At any point, the strongest AP shown should be on a different
channel than the next best choice.
