The MSC instructs the base station and mobile user to move to an unused forward and reverse voice channel pair. Roaming All cellular systems provide a service called roaming. This allows subscribers to operate in service areas other than the one from which the service is subscribed. Mobile radio service was introduced in St. Louis in 1946. This radio dispatching system had an operator who patched the caller to the PSTN. Later, IMTS allowed customers to dial their calls without an operator. From this humble beginning came the present cellular phone system.
Cellular Communications Definition A cellular mobile communications system uses a large number of low-power wireless transmitters to create cells—the basic geographic service area of a wireless communications system. Variable power levels allow cells to be sized according to the subscriber density and demand within a particular region. As Mobile network providers install several thousands of base stations each with a smaller cell instead of using power full transmitters with large cells because, when the cell size is small we can have the following advantages: Some of the disadvantages of cellular systems are: 1. Infrastructure needed.

In the early 1980s, most mobile telephone systems were analog rather than Portable Cellular Systems Application Note In order to use cell phones in an area with limited or no service coverage, a cellular network must first be established. The portable cellular system acts like a stationary cell tower providing a cellular communication link to the mobile devices within range of its broadcast antenna. Most
