What is IEEE 802.11a Wireless LAN(WLAN) technology?

● When there's need for much higher performance.  802.11a is the ideal technology to support higher end applications involving video, voice, and the transmission of large images and files.

● When there is requirement for Higher Frequency band to avoid significant RF interference  caused by other devices. The use of 802.11a operating in the 5 GHz band will avoid this interference.

● When the End users are densely populated. Places such as computer labs, airports, and convention centers need to support lots of end users in a common area competing for the same access point, with each user sharing the total throughput. The use of 802.11a will handle a higher concentration of end users by offering greater total throughput.
