| Product Impact | Feature | 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 | Additional Country Codes Support | This release introduces support for these countries in the -ROW domain. Cisco Catalyst IW9167E AP: Trinidad (TI) Cisco Catalyst IW9165E AP: Cameroon (CM), Ghana (GH), and Kuwait (KW). For more information, see the chapter Fixed Domains and Country Codes. |
