Detailed explanation-1: -IEEE 802.11a-1999 (802.11a)-This standard supports transmission speed of up to 54Mbps on the 5GHz frequency band. IEEE 802.11b-1999 (802.11b)-This standard supports transmission speed of up to 11Mbps on the 2.4GHz frequency band.
Detailed explanation-2: -The 2.4 GHz band provides the most coverage but transmits data at slower speeds. The 5 GHz band provides less coverage but transmits data at faster speeds. The 6 GHz band, introduced with the new WiFi 6E standard, provides the least coverage but transmits data at the fastest speeds of the three frequencies.
Detailed explanation-3: -2.4 GHz WLAN/Wi-Fi Technology (802.11 b/g/n) uses the frequency band from 2401 to 2484 MHz. This bandwidth is divided among 14 channels. Each of the WLAN / Wi-Fi Channels are spaced 5 MHz apart, except the last two channels which are spaced 12 MHz apart.
