  802.11
  
  The IEEE developed the 802.11 standard for wireless local area networks (WLANs). There are four specifications including 802.11, 802.11a, 802.11b, and 802.11g. Each 802.11 standard operates in a different GHz range and/or offers a different speed. 802.11 applies to wireless LANs and provides 1 or 2 Mbps transmission in the 2.4 GHz band using either frequency hopping spread spectrum (FHSS) or direct sequence spread spectrum (DSSS).
  
  802.11a
  
  The 802.11a specification operates in the unlicensed 5GHz range and offers data speeds up to 54Mbps. The 5GHz range is not yet crowded so it offers advantages in speed over the 802.11b specification which uses the more crowded 2.4GHz range (which can interfere with cordless phones, microwaves, etc.). However, the range and speed of 802.11a are inversely related – which is why 802.11a was not adopted as the WiFi standard. 802.11a uses a modulation scheme known as orthogonal frequency-division multiplexing (OFDM) versus the FHSS or DSSS. Most 802.11a products are not compatible with 802.11b or 802.11g products (although this is changing).
  
  802.11b
  
  The 802.11b standard operates in the 2.4GHz range and offers a data speeds up to 11Mbps. 802.11b is the de facto standard for WiFi services because of its availability and low price (although 802.11g will now quickly become the standard). While slower than 802.11a, 802.11b is still as fast as 10BaseT Ethernet service. 802.11b uses direct sequence spread spectrum (DSSS) and complementary code keying (CCK) modulation. 802.11b was certified by the IEEE in 1999.
  
  
  802.11g
  
  802.11g was approved on June 11, 2003 and offers data speeds up to 54Mbps and operates in the 2.4GHz and 5GHz range making it backward compatible with 802.11b. Even before the IEEE approval, it was clear the 802.11g would become the standard for WiFi services and leading manufacturers started to release products in early 2003. 802.11g uses OFDM modulation but, for backward compatibility with 802.11b, it also supports complementary code keying (CCK) modulation.
  
  
• The IEEE standards process has always benefited from being an open process in which any interested party can participate. With the introduction of Get IEEE 802 ™, the entire world will benefit from open and unencumbered access to these high quality standards for leading edge networking and communications technologies, observed Howard Frazier, Founder of Dominet Systems, formerly of Cisco and Sun.
