2.6.1 Radio Channels
There are 13 regulatory radio channels predefined for the transportation of
data in a wireless LAN. Local regulations determine which of these
channels that can be used by the Ericsson W20.
The following settings concerning radio frequencies are displayed and
possible to modify on the Wireless LAN page:
Region
The country domain, which is one of the
following:
Europe
US
Canada
South Africa
Australia
New Zeeland
Malaysia
Singapore
Radio channel
The radio channel for wireless LAN
communication, either
Auto (default) or
1-13
Transmit power [dBm]
The radio transmission level that
determines the signal range:
0-20
Default is 20.
To make sure the Ericsson W20 operates on correct radio frequencies
according to local regulations, you have to state in which region you reside.
After this you cannot select any radio channel which would be against the
local regulations. Select your country domain from the Region list on the
Wireless LAN page.
Use the Radio channel list to select which one of the allowed radio
channels to use, or select Auto to let the Ericsson W20 automatically
select a channel (recommended). If you want information about adjacent
wireless networks to make your choice, click Scan for wireless networks
