Final answer:
Option B: The maximum bandwidth of an 802.11g WLAN is 54 Mbps, which was an improvement over the earlier 802.11b standard and uses the 2.4 GHz frequency band with OFDM technology.
Step-by-step explanation:
The maximum bandwidth of an 802.11g wireless LAN (WLAN) is 54 Mbps (megabits per second). The 802.11g standard, which was ratified in 2003, represents an improvement over the earlier 802.11b standard that had a maximum bandwidth of 11 Mbps. The 802.11g standard operates in the 2.4 GHz frequency band and is backwards compatible with 802.11b devices. It uses a technology called orthogonal frequency-division multiplexing (OFDM) to increase its data transfer rate. Although newer standards like 802.11n and 802.11ac have since emerged with even higher bandwidths, the 54 Mbps maximum of 802.11g was a significant boost in speed for wireless networking when it was introduced.
The maximum bandwidth of an 802.11g wireless LAN (WLAN) is 54 Mbps (megabits per second). The 'g' in 802.11g refers to the IEEE (Institute of Electrical and Electronics Engineers) standard that is used in the WLAN. This standard provides for a maximum data rate of 54 Mbps.
