Wireless Communication Systems

The ability to communicate with people on the move has evolved remarkably since Guglielmo Marconi first demonstrated radio’s ability to provide continuous contact with ships sailing the English Channel in 1897. Since then new wireless communications methods and services are enthusiastically adopted by people throughout the universe.
With the development of highly reliable, miniature, solid-state radio frequency hardware in the 1970s, the wireless communications era was born.

Examples: Most people are familiar with a number of mobile radio communication systems used in everyday life. Garage door openers, remote controllers for home entertainment equipment, cordless telephones, hand-held walkie-talkies, pagers (also called paging receivers or “beepers”), and cellular telephones are all examples of mobile radio communication systems.

Paging Systems

Paging systems are communication systems that send brief messages to a subscriber. Depending on the sort of service, the message could also be either a numeric message, an alphanumeric message, or a voice message. Paging systems are typically utilized to notify a subscriber of the necessity to call a specific phone number or visit a known location to receive further instructions.

Cellular Telephone Systems

Cellular radio systems provide high-quality service that's often comparable to that of the landline telephone systems. High capacity is achieved by limiting the coverage of every base station transmitter to a little geographic area called a cell in order that an equivalent radio channels could also be reused by another base station located a long way.
