THE ROLE OF WLL
Fig. 43.1 illustrates a simple WLL configuration. A WLL provider services one or more cells. Each cell includes a base station antenna, mounted on top of a tall building or tower. Individual subscribers have a fixed antenna mounted on a building or pole that has an unobstructed line of sight to the base station antenna. From the base station, there is a link, which may be either wired or wireless, to a switching centre. The switching centre is typically a telephone company local office, which provides connections to the local and long-distance telephone networks. An internet service provider (ISP) may be located at the switch or connected to the switch by a high-speed link.
