IEEE 802.11a

IEEE 802.11a is a wireless standard in the series of 802.11 standards. The 802.11a standard is an improved version of the original 802.11 standard, which has been introduced in 1999. The data transfer rate in IEEE 802.11a standard is up to 54 Mbps, which operates at a frequency of 5 GHz. In IEEE 802.11a, the Orthogonal Frequency Division Multiplexing (OFDM) modulation scheme is used for the generation of signals. The security protocols are the same as those of the 802.11 standard. The 802.11a standard provides more enhanced support for features such as voice, video, and image application, but is not interoperable with the 802.11b standard.
