Final answer:
The maximum bandwidth for an 802.11a WLAN is 54 Mbps. This was an improvement from the earlier 802.11b standards and is less than the newer 802.11n and 802.11ac standards.
Step-by-step explanation:
The maximum bandwidth of an 802.11a wireless LAN (WLAN) is 54 Mbps. The IEEE 802.11a standard operates in the 5 GHz frequency band and was one of the first Wi-Fi communication standards to provide speeds higher than the older 802.11b standard, which offered a maximum bandwidth of 11 Mbps.
In contrast, newer standards like 802.11n can deliver speeds up to 600 Mbps, and 802.11ac can even reach speeds beyond 1 Gbps under certain conditions.
