Final answer:
The maximum bandwidth of an 802.11b WLAN is 11 Mbps. It's an older standard that operates in the 2.4 GHz band and offers wider coverage with lower data rates compared to newer standards.
Step-by-step explanation:
The maximum bandwidth of an 802.11b wireless LAN (WLAN) is a) 11 Mbps. This specification is one of the older IEEE standards for wireless local area networks. It operates in the 2.4 GHz band and was commonly used before more advanced standards like 802.11a, 802.11g, 802.11n, and others emerged, offering higher bandwidths.
It's important to note that while 802.11b offers lower bandwidth compared to newer standards, its signal range is generally greater, which may be beneficial in environments where coverage is more important than high data rates.
