"High-Rate" radio frequency networking technology developed by the Institute of Electrical and Electronic Engineers (IEEE). Most wired networks conform to 802 3, the specification for CSMA/CD-based Ethernet networks, or 802.5, the specification for token ring networks. 802.11b utilizes the license-free bandwidth of 2.4 GHz, and most products utilize DSSS. Further 802.11 variants include: · 80211a: a 54 Mbps solution utilizing the 5 GHz space; and · 802.11e: an enhancement to the MAC for QoS.

Often called Wi-Fi, 802.11b is backward compatible with 802.11. IEEE 802.11b has a data transmission rate of 11 Mbps, sufficient for most non-motion data transmission applications.

An IEEE specification for wireless communication and data synchronization that competes with Bluetooth. Also known as Wi-Fi. Apple Computer's version of 802.11b is called AirPort.

Insertion Loss is the amount of the signal that is lost (attenuation) as the signal passes through a connection or interface.
