A cellular networka group or system of interconnected people or things. or mobile networka group or system of interconnected people or things. is a communication networka group or system of interconnected people or things. where the last link is wireless. The networka group or system of interconnected people or things. is distributed over land areas called cells, each served by at least one fixed-location transceiver, known as a cell site or base station. This base station provides the cell with the networka group or system of interconnected people or things. coverage which can be used for transmission of voice, data and others. A cell might use a different set of frequencies from neighboring cells, to avoid interference and provide guaranteed service quality within each cell.

When joined together these cells provide radio coverage over a wide geographic area. This enables a large numberA unit of abstract mathematical system subject to the laws of arithmetic. of portable transceivers (e.g., mobile phones, pagers, etc.) to communicate with each other and with fixed transceivers and telephones anywhere in the networka group or system of interconnected people or things., via base stations, even if some of the transceivers are moving through more than one cell during transmission.

Cellular networksa group or system of interconnected people or things. offer a numberA unit of abstract mathematical system subject to the laws of arithmetic. of desirable features:

More capacity than a single large transmitter, since the same frequency can be used for multiple links as long as they are in different cells Mobile devices use less power than with a single transmitter or satellite since the cell towers are closer Larger coverage area than a single terrestrial transmitter, since additional cell towers can be added indefinitely and are not limited by the horizon

Major telecommunications providers have deployed voice and data cellular networksa group or system of interconnected people or things. over most of the inhabited land area of the Earth. This allows mobile phones and mobile computing devices to be connected to the public switched telephone networka group or system of interconnected people or things. and public Internet. Private cellular networksa group or system of interconnected people or things. can be used for research or for large organizations and fleets, such as dispatch for local public safety agencies or a taxicab company.[2]

Excellent (but very technical) video about mobile networksa group or system of interconnected people or things.

In the video below, you get an excellent description and explanation how mobile and cellular networksa group or system of interconnected people or things. work. This is a pretty technical video, but it's high quality and worth watching.
