7.1 Site Survey Tool
It is recommended to do site surveys with the built-in tools in the handset.
This provides a true measurement of the RF environment based upon the radio
of the handset. Wireless analyzers may be used to provide additional assistance
during a site survey.
7.2 Scan the Channels
To be able to use the site survey functions in the handset, it must be configured
correctly.
Default configuration for the handset is to use channels 1, 6 and 11. If the handset
is intended for site survey use, scanning all channels will be limited to 1, 6 and 11.
The table is upgraded regularly, starting with scanning channel 1, then 6 and last
11. In between, the handset is in sleeping mode. The handset consults this table
when making roaming decisions.
It is possible to scan all 802.11b/g/n channels, or scan all 802.11a/n channels by
setting the parameter 802.11b/g/n channels or 802.11a/n channels to “All”,
respectively.
For 802.11b/g/n channels, it is strongly recommended to set back the handset to
“1,6,11” before normal use. For 802.11a/n channels, it is strongly recommended
to set back the handset to “UNII-1” before normal use.
The World mode regulatory domain will also affect which channels that may be
used. To scan channels 1-11 it is recommended that the handset is configured so
the “World mode regulatory domain” parameter is set to “USA”. If also scanning
of channels 12 and 13 is of interest use value “ETSI”.
There are three ways of scanning channels:
• Scan all channels
• Scan a specific channel
