Essay On Advantages And Disadvantages Of Cellular Network

A cellular network or mobile network is a radio network distributed over land areas called cells, each served by at least one fixed-location transceiver, known as a cell site or base station. In a cellular network, each cell uses a different set of frequencies from neighboring cells, to avoid interference and provide guaranteed bandwidth within each cell.

When joined together these cells give radio coverage over a wide geographic area. This enables a large number of portable handsets (e.g., cell phones, pagers, and so on.) to speak with each other and with settled handsets and phones anyplace in the system, by means of base stations, regardless of the possibility that a portion of the handsets are traveling through more than one cell during transmission.

Cellular networks offer a number of advantages over alternative solutions:

•

With FDMA, the transmitting and accepting frequencies used in each cell are not quite the same as the frequencies utilized as a part of each neighboring cell. In a basic taxi framework, the cabbie physically tuned to a recurrence of a picked cell to get a solid flag and to maintain a strategic distance from obstruction from signals from other cells.

The principle of CDMA is more complex, but achieves the same result; the distributed transceivers can select one cell and listen to it.

Other available methods of multiplexing such as polarization division multiple access (PDMA) and time division multiple access (TDMA) cannot be used to separate signals from one cell to the next since the effects of both vary with position and this would make signal separation practically impossible. Time division multiple access, however, is used in combination with either FDMA or CDMA in a number of systems to give multiple channels within the coverage area of a single
