Wireless communication

Wireless communicaiton is used to meet many needs. it has four Modes Radio , Free- space optical , sonic, Electromagnetic induction. Perhaps The most common wireless technologies use radio. With radio waves distances can be short, such as a few meters for television or as far as thousands or even millions of kilometers for deep-space radio communications. It encompasses various types of fixed, mobile, and portable applications, including two-way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking. Other examples of applications of radio wireless technology include GPS units, garage door openers, wireless computer mice, keyboards and headsets, headphones, radio receivers, satellite television, broadcast television and cordless telephones. Radio communication, microwave communication, for example long-range line-of-sight via highly directional antennas, or short-range communication. Base stations - BS - may be stand alone transmission systems that are part of a cell site and are composed of an antenna system (typically a radio tower), building, and base station radio equipment. Base station radio equipment consists of RF equipment (transceivers and antenna interface equipment), controllers, and power supplies.

Base station radios are coordinated by the GSM system's BSC. The radio transceiver section is divided into transmitter and receiver assemblies. The transmitter section converts a voice signal to RF for transmission to wireless telephones and the receiver section converts RF from the mobile device to signals tha tare routed to the MSC or packet switching network. The controller section commands insertion and extraction of signaling information.

Radio Antenna Towers - Wireless base station antenna heights can vary from a few feet to more than three hundred feet. Radio towers raise the height of antennas to provide greater area coverage. There may be several different antenna systems mounted on the same radio tower. we Sumlo are stocking A high 40m tower should be contain Antenna, Feeder coaxial cable, connector , feeder clamp, Jumper...

A typical cell site antenna system has multiple antennas. One antenna is used for transmitting and two are used for reception for each radio coverage sector.

Radio Equipment - in the base station contains audio processing, modulation, and RF power amplifier assemblies. In the GSM system, the transmitter power level for the control channel is usually fixed to define the cell boundaries (e.g. a control channel). The power level of dedicated (individual) channels may dynamically change to the lowest level possible that allows quality communication with the wireless telephone.
