the 802.11a amendment to the original standard was ratified in 1999. the 802.11a standard uses the same core protocol as the original standard, operates in 5 ghz band, and uses a 52-subcarrier orthogonal frequency-division multiplexing (ofdm) with a maximum raw data rate of 54 mbit/s, which yields realistic net achievable throughput in the mid-20 mbit/s. the data rate is reduced to 48, 36, 24, 18, 12, 9 then 6 mbit/s if required. 802.11a originally had 12/13 non-overlapping channels, 12 that can be used indoor and 4/5 of the 12 that can be used in outdoor point to point configurations. recently many countries of the world are allowing operation in the 5.47 to 5.725 ghz band as a secondary user using a sharing method derived in 802.11h. this will add another 12/13 channels to the overall 5 ghz band enabling significant overall wireless network capacity enabling the possibility of 24+ channels in some countries. 802.11a is not interoperable with 802.11b as they operate on separate bands, except if using equipment that has a dual band capability. most enterprise class access points have dual band capability.
