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

period, QoS, and Privacy.
