Wi-Fi wireless networking. 802.11g supports
wireless local area network (WLAN) communications among computers, broadband routers and many other consumer devices. It replaced the older
802.11b technology.
802.11g Performance
802.11g Wi-Fi supports maximum network bandwidth of 54
Mbps compared to 11 Mbps for 802.11b and 150 Mbps or more for the newer
802.11n Wi-Fi.
802.11g Radio Signaling
To maintain backward compatibility with older Wi-Fi network equipment, 802.11g uses the same 2.4 GHz range of communication frequencies as 802.11b.
