Any communication that uses an access point travels through the distribution service, including communications between two mobile stations associated with the same access point. 11 network. 11, except in terms of the services it must offer. Association Delivery of frames to mobile stations is made possible because mobile stations register, or associate, with access points. The distribution system can then use the registration information to determine which access point to use for any mobile station.

TV signals are vastly more complex and have a correspondingly larger bandwidth of 6 MHz. The use of a radio spectrum is rigorously controlled by regulatory authorities through licensing processes. , regulation is done by the Federal Communications Commission (FCC). Many 7 FCC rules are adopted by other countries throughout the Americas. European allocation is performed by CEPT's European Radiocommunications Office (ERO). Other allocation work is done by the International Telecommunications Union (ITU).

Stations are computing devices with wireless network interfaces. Typically, stations are battery-operated laptop or handheld computers. There is no reason why stations must be portable computing devices, though. In some environments, wireless networking is used to avoid pulling new cable, and desktops are connected by wireless LANs. 11 network is the basic service set (BSS), which is simply a group of stations that communicate with each other. [1] When a station is in the basic service area, it can communicate with the other members of the BSS.
