802.11 A: IEEE standard completed in 1999. Physical layer operates within the 5 GHz radio band and offers up to12 non-overlapping channels (as opposed to three with 802.11b). It uses orthogonal frequency divisionmultiplexing to offer maximum standardized data rate of 54 Mbps.

802.11d: Standard completed in 2001. Radio emissions are subject to regulatory limits. 802.11 was written tocomply with the regulatory limits in the US., Canada, and Europe. New regulators may specify different constraintsfor transmit power and allowed frequencies. Rather than revise the specification when new regulators issues rules,802.11d allows an access point to describe allowed configurations to clients to make deployment easier.

802.11f: Standard still under progress. It defines how clients work with access points, but does not define hownetworks of access points provide a single seamless network. Not relevant now because most large networks aresingle vendor; may be more important as multi-vendor become more common.
