IEEE 802.11b
IEEE 802.11b is an industrial standard for Wireless Local Area Networking
(WLAN), which enables wireless communications over a long distance.
The speed of the connection between wireless devices will vary with range and
signal quality. To maintain a reliable connection, the 802.11b system automatically
fallback from 11 Mbps to 5.5, 2 or 1 Mbps as range increases or signal quality
decreases.
