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 can 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, configure the site survey

functions 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 is limited to 1, 6, and 11.

The table is upgraded regularly, starting with scanning channel 1, then 6 and finally 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 can 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 scanning of channels 12 and 13

is also of interest use value “ETSI”.

There are two ways of scanning channels:

• Scan all channels

• Scan a specific channel
