standards80211a
Standards80211a, commonly referred to as IEEE 802.11a, is a wireless local area network standard published by the IEEE in 1999 as part of the 802.11 family. It was designed to provide higher data rates in the 5 GHz band using a modulation and coding scheme distinct from the earlier 2.4 GHz standards, enabling faster wireless connections for enterprise and other WLAN environments.
The technical core of 802.11a is its use of Orthogonal Frequency Division Multiplexing (OFDM) on 20 MHz
In terms of compatibility, 802.11a operates in a different frequency band than the earlier 802.11b/g standards,
