unlicensed use in the ISM (Industrial, Scientific and Medical) band. Spectrum in the

vicinity of 2.4 GHz, in particular, is being made available worldwide. This presents a

truly revolutionary opportunity to place convenient high-speed wireless capabilities in

the hands of users around the globe.

10. What is the IEEE 802.11g standard?

Approved in June, 2003 as an IEEE standard for wireless local area networks

(WLANs), 802.11g offers wireless transmission over relatively short distances at up

to 54 megabits per second (Mbps) compared with the 11 megabits per second of the

802.11b (Wi-Fi) standard. Like 802.11b, 802.11g operates in the 2.4 GHz range and is

thus compatible with it.
