Troubleshooting What's the difference between 802.11b, 802.11g and 802.11a? Currently there are three levels of wireless networking standards, which transmit data at very different maximum speeds. Each is based on the designation 802.11x, so named by the IEEE, the board that is responsible for certifying networking standards. The most common wireless networking standard, 802.11b, transmits information at 11Mbps; 802.11a and 802.11g work at 54Mbps. See the following chart for more detailed information. Wireless Comparison Wireless Technology Speed Frequency Compatibility Range 802.11b 802.11g 802.11a 11Mbps Common household devices such as cordless phones and microwave ovens. May interfere with the 2.4GHz unlicensed band Compatible with 802.11g Depends on interference typically 50-300 ft. indoors 54Mbps Common household devices such as cordless phones and microwave ovens. May interfere with the 2.4GHz unlicensed band Compatible with 802.11b Depends on interference typically 50-300 ft. indoors 54Mbps 5GHz uncrowded band Incompatible with 802.11b or 802.11g Less interference - range is typically 50-100 feet Adoption Price Mature - widely adopted Inexpensive Expected to continue to grow in popularity Slow adoption for consumers more popular in business More expensive Most expensive 126
