Most chips also support an Atheros Turbo Mode (TM) that operates in

Some chips also support Turbo mode in the 2.4Ghz range with 802.11g

(Note that Turbo modes are, however,

only interoperable with other Atheros-based devices.)

AR5212-based devices also support half- (10MHz) and quarter-width (5MHz) channels.
