Definition: 802.11b is a Wi-Fi wireless network communication technology. It is one of the 802.11 series of IEEE standard technologies and was widely used in first-generation Wi-Fi home networking products after its introduction in 1999. 802.11b has since been rendered obsolete by the newer Wi-Fi standards 802.11g and 802.11n.
802.11b Performance802.11b LANs support a theoretical maximum data rate of 11 Mbps. Although comparable to traditional Ethernet (10 Mbps), its performs significantly slower than newer Wi-Fi and Ethernet technologies including 802.11g and Fast Ethernet.
802.11b and Wireless InterferenceTransmitting in the unregulated 2.4 GHz frequency range (like 802.11g), 802.11b transmitters can encounter radio interference from other wireless household products like cordless telephones, microwave ovens, garage door openers, and baby monitors.
