Sequenced Explanations:
This short explanation on how a cell
phone work is really wonderful. A cell phone or in long term “cellular
telephone’ works by transmitting signals of radio to towers of cellular. The
towers are networked to a central switching station. The connection usually
uses wire, fiber optic-cables, or microwave.
Then the central switching station which
handles calls in certain given area is directed connected to the wire-based
telephone system. Cellulars are pick up by the towers and relayed to another
cellular telephone user or the user of wire-based telephone network.
The towers vary in the capacity and
capability to receive signals. Some can receive the signal from short distance
and the others can receive more distance. However, there are usually more than
one tower in certain given area so that the system can handle the increasing
telephone traffic.
