This note addresses the following topics:

Understanding Radio Channels and Frequencies, page 1

•

Determining the Radio Type, page 2

Configuring a Channel or Frequency, page 2

Understanding Radio Channels and Frequencies

By default, the channel selected by Cisco wireless devices is the one that is least congested. At startup
and by default, wireless devices passively scan for and select the least-congested channel. The channel
settings on wireless devices correspond to the frequencies available in your regulatory domain.

In the European Telecommunications Standards Institute (ETSI) domain, the regulatory agencies do not
allow the channel to be set on 5.0 GHz (802.11a/h) radios by the users. However, channel groups can be

blocked

on wireless devices running ETSI images. When a wireless device boots from an ETSI image,

it automatically selects the least congested channel where radar is not detected by using Dynamic
Frequency Selection (DFS).

Transmission Power Control (TPC) is used to automatically adjust the transmission power level on
5.0-GHz radios, also to avoid interfering with radar.

To set the radio channel for dynamic frequency selection (DFS), see

Dynamic Frequency Selection
