Explanation:
Detailed explanation-1: -2.4 GHz WLAN/Wi-Fi Technology (802.11 b/g/n) uses the frequency band from 2401 to 2484 MHz.
Detailed explanation-2: -802.11b used the same 2.4 GHz frequency as the original 802.11 standard. It supported a maximum theoretical rate of 11 Mbps and had a range up to 150 feet. 802.11b components were inexpensive, but the standard had the slowest maximum speed of all the 802.11 standards.
Detailed explanation-3: -802.11g delivers the same 54 Mbps maximum data rate as 802.11a, but operates in the same 2.4 GHz band as 802.11b. It also provides backward compatibility with existing 802.11b devices.
