Final answer:
A Wireless Access Point (WAP) or Wireless Network Access Point provides IEEE 802.11 WLAN service to areas designated for wireless coverage in the BITI system.
Step-by-step explanation:
The component that provides IEEE 802.11 WLAN service to approved coverage areas such as flight lines, mechanic back shops, classrooms, and select conference rooms within the context of the BITI (Base Information Transport Infrastructure) is commonly referred to as a Wireless Access Point (WAP) or Wireless Network Access Point. These devices act as hubs for WLAN communication, allowing approved devices within their coverage area to connect to a wired network wirelessly, facilitating internet access and network resources. They are strategically placed in locations where network coverage is required.
