[...] It refers to wireless( 802.11 Where wireless is useful? Sometimes wireless is implemented in areas where network cable is difficult to install Useful for people who are constantly on the move such as doctors and nurses Isolated areas and bulidings Departments where the physical setting changes frequently. Structures, such as historical buildings, where cabling would be difficult. Transmissions and receptions are achieved by means of an antenna and can be Directional Point-to-point focused beams employing high frequencies. Omni directional Waves propagating in all directions using signals of lower frequencies. [...]
