IEEE 802.16 - Broadband Wireless Access Standard
IEEE 802.16 group works on Broadband Wireless Access standards. It was established in 1999 by the IEEE Standard Board.
The 802.16 family of standards has the official name WirelessMAN or Wireless Metropolitan Area Network. There is also name WiMAX or Worldwide Interoperability for Microwave Access and industry group called The WiMAX Forum. The mission of this forum is to achieve interoperability of broadband wireless products.
If you want to find out more about the technology of the 802.16 standard, read What is WiMAX.
This technology has its own pros and cons. Check all about the cons of WirelessMan on the Disadvantages of WiMAX technology.
Original 802.16 standard was approved in December 2001. It described point to multipoint Broadband Wireless transmission in frequency of 10-66 GHz. It uses single carrier physical modulation.
Amendment 802.16a brought new frequency of 2-11 GHz. It uses Orthogonal Frequency Division Multiplex - OFDM and Orthogonal Frequency Division Multiple Access - OFDMA.
802.16c has brought modifications for 10-66 GHz band.
802.16d standard was delivered in September 2003 to align 802.16 standard with ETSI HIPERMAN standard.
802.16e-2005 has brought better Quality of Service – QoS, and OFDMA. This standard is also often called Mobile WiMAX. The 802.16 standard defines WirelessMan technology. The 802.11 standards describe WLAN (Wireless Local Area Network) radio signals and WiFi technology. There are four standards which are for defining different WiFi radio signals (802.11a, 802.11b, 802.11g and 802.11n) and one IEE standard for wireless security – IEEE 802.11i.
