802.11b

The 802.11b standard for wireless local area networks (WLANs) - often called Wi-Fi - is part of the 802.11 series of WLAN standards from the Institute of Electrical and Electronics Engineers (IEEE). 802.11b is backward compatible with 802.11.

Like other 802.11 standards, 802.11b uses the Ethernet protocol and CSMA/CA (carrier sense multiple access with collision avoidance) for path sharing. The modulation used in 802.11 has historically been phase-shift keying (PSK). The modulation method selected for 802.11b is known as complementary code keying (CCK), which allows higher data speeds and is less susceptible to multipath-propagation interference.
