4.6 DCS (Dynamic Channel Selection)

To enable DCS, Click Wireless> 5 GHz Radio> DCS

The DCS parameter allows an AP to monitor the retransmissions of packets transmitted to

the associated SU on the current operating channel.

When the average of Local RTX percentage of associated SU crosses user configured value,

before switching to new channel, AP evaluates local RTX percentage for 30 sec and triggers

Spectrum Analyser to scan the medium.

The Spectrum Analyser scans for less interference channel and associates the high priority

SU to the best channel available.

 This feature is available only in AP with 5GHz.

 The DCS threshold is user selectable range (0-100)% and is activated only when DCS

is enabled.

 Default chosen DCS threshold is 50%, when this percentage limit exceeds, the AP

activates spectrum analyser and assigns best channel to the desired SU.

 Respective logs will be generated under Monitor> Logs> Wireless section as

For example: <time stamp>: DCS triggered (when SU request AP)

<Time stamp>: DCS selected best channel (When AP assigns new channel to SU)
