Detailed explanation-1: -802.11g is the third modulation standard for wireless LANs. It works in the 2.4 GHz band (like 802.11b) but operates at a maximum raw data rate of 54 Mbit/s.
Detailed explanation-2: -The 802.11g technology for wireless networks is designed for transmission over short distances. The maximum network bandwidth is 54 Mbps in the 2.4 GHz bands.
Detailed explanation-3: -802.11g is a proposed standard that describes a wireless networking method for a WLAN that operates in the 2.4GHz radio band (ISM: Industrial Scientific Medical frequency band). It transfers data at up to 54Mbps.
Detailed explanation-4: -Both IEEE 802.11a and IEEE 802.11g use a more advanced form of modulation called orthogonal frequency-division multiplexing (OFDM). Using OFDM in the 2.4 GHz band, IEEE 802.11g achieves speeds of up to 54 Mbps.
Detailed explanation-5: -802.11b and 802.11g use the 2.4-GHz ISM band, operating in the United States under Part 15 of the U.S. Federal Communications Commission Rules and Regulations.
