Description

Upgrade

UNII-3 band with DFS support for Great Britain Country Code

 

From this release, the Cisco Catalyst IW9167E and IW9165D Access Points (APs) include support for the UNII-3 band with Dynamic Frequency Selection (DFS) for Great Britain. This capability enables the APs to function in the 5.8 GHz frequency band in Ultra-Reliable Wireless Backhaul (URWB) mode for the country code GB (Great Britain). This enhancement improves wireless connectivity in radar-sensitive environments by utilizing the UNII-3 band and DFS support.

To activate this frequency band, the APs must be in the -ROW domain.

In country code GB, the 5.8 GHz frequencies support channel bandwidths of 20 MHz.

For more information, see the chapter Configure and validate radio channel and bandwidth.

Upgrade

5855-5935 MHz Frequency Support

From this release, the Cisco Catalyst IW9167E, IW9165D, and IW9165E APs support the Intelligent Transport Systems (ITS) frequency band within the European regulatory domain (-E PID). For more information, see the chapter Configure and validate radio channel and bandwidth.

Upgrade
