These antennas are connected to a local phone network, or directly to another wireless phone.
Cellular phones use the same frequency over and over by dividing up geographic areas into cells.
These cells can be as large as an entire country, or as small as a single building. PCS cells tend to be smaller than traditional analog cells. This gives PCS the capacity to handle more subscribers. As the user moves from cell to cell, the call is handed off from one antenna to the next. Large PCS service areas also allow for wider roaming, and new data services linked to the Internet.
