A method provides forward compatibility hooks for DFS and TPC for WLAN, so that the same mechanisms can be employed (with only minor changes/additions) for other regulatory domains, other bands, and/or other purposes. The current IEEE 802.11 h standard defines mechanisms for dynamic frequency selection (DFS) and transmit power control (TPC) that may be used to satisfy regulatory requirements for operation in the 5 GHz band in Europe. The present method provides a format to allow other bands, and relates to the supported channels element, channel switch announcement element, and the Basic/CCA/RPI histogram request/report. The method optionally reserves more than 3-bits in the Basic report (Map subfield).
