wireless routers to wireless PCI client cards.
IEEE 802.11 – Wireless Network Specifications
• 802.11 -- applies to wireless LANs (Networks) 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).
• 802.11b (also referred to as 802.11 High Rate or Wi-Fi) -- an extension to 802.11 that applies to
wireless LANs and provides 11 Mbps transmission (with a fallback to 5.5, 2 and 1 Mbps) in the 2.4
GHz band. 802.11b uses only DSSS. 802.11b was a 1999 ratification to the original 802.11
standard, allowing wireless functionality comparable to Ethernet.
• 802.11g -- applies to wireless LANs and provides 54 Mbps in the 2.4 GHz band. Backwards
compatible with IEEE 802.11b products.
