Configuration and Management
2.6.2 Region
Wireless devices are thoroughly regulated and the countries have slightly
different regulations. Therefore, the geographical region where the Ericsson
W21 is used must be stated to make sure the correct radio frequencies are
used when transmitting data.
Select the geographical region in which you reside from the “Region” drop-
down list and click
Apply to save the setting.
2.6.3 Radio Channel
The radio channel must be in accordance with the previous set region and
only channels that are allowed in the configured region are available in the
“Radio channel” drop-down list.
By selecting “Auto” (recommended) the radio will automatically scan each
valid channel and choose the one with least interference.
Select either “Auto” or a specific channel number from the “Radio channel”
drop-down list and click
Apply to save the setting.
2.6.4 Transit Power [dBm]
To avoid interference with other wireless networks, the transmit power level
can be reduced. If you want to change the transmit power level according

power [dBm]” drop-down list and click
Apply to save the setting.
