802.1xx Wireless Standards

Standards - Terms - Readings

The 802.1xx family of standards were developed by the IEEE for Wireless Applications. They specify and OTA (Over the Air) interface between access points and clients, or between wireless clients.

  • 802.11 - Wireless LAN applications in the 2.4 GHz band, using both frequency hopping spread spectrum (FHSS) or direct sequence spread spectrum. Supplies 1 or 2 Mbps speeds.

  • 802.11a: - Extension to 802.11, utilizing OFDM (Orthogonal Frequency Division Multiplexing) that provides up to 54 Mbps in the the 5 GHz Band

  • 802.11b - Extension to 802.11, provides 11 Mbps Transmission, auto negotiating back to 5.5, 2, and 1 Mbps in the 2.4 Ghz Band. From 1999 allowed wireless functionality similar to Ethernet.

  • 802.11g - Provides up to 54 Mbps over the air rate in the 2.4 GHz band

  • 802.16 - Referred to as WiMAX or MAN (Metropolitan Area Network) a specification for fixed broadband, point to multipoint, wireless metropolitan access networks. The standard use in the licensed 10GHz and 66GHz bands, and between 2GHz/11GHz (licensed and unlicensed) bands. It also defines a MAC layer that supports multiple physical layer specifications customized for the frequency band of use and their associated regulations. Very high bit rates in both the up and downstream for ranges up to 30 miles and supports such services as VoIP, IP bridging and TDM voice and data. MAC Layer attributes makes advanced QOS features available including compatibility with ATM
