Final answer:
The WLAN technology that supports a data transmission rate of 11 Mbps is 802.11b. It operates in the 2.4 GHz band and was common before faster standards like 802.11g and 802.11n emerged.
Step-by-step explanation:
The WLAN technology that supports a maximum data transmission rate of 11 Mbps is 802.11b. The 802.11 standards are part of the IEEE specification for wireless local area networks (WLANs). Specifically, 802.11b operates in the 2.4 GHz band and is capable of providing up to 11 Mbps throughput. This standard was widely used in the past, but newer standards such as 802.11g and 802.11n offer higher data rates and are generally preferred for modern WLAN applications.
