A battery charger, recharger, or simply charger, is a device that in an by running through it. The charging protocol—how much and current, for how long and what to do when charging is complete—depends on the size and type of the battery being charged. Some battery types have high tolerance for overcharging after the battery has been fully charged and can be recharged by connection to a constant or a constant

A is a network of handheld (cell phones) in which each phone communicates with the by through a local antenna at a cellular base station (cell site). The coverage area in which service is provided is divided into a mosaic of small geographical areas called "cells", each served by a separate low power multichannel and antenna at a base station. All the cell phones within a cell communicate with the system thr.

A BTS is usually composed of: Transceiver (TRX) Provides transmission and reception of signals. It also does sending and reception of signals to and from higher network entities (like the base station controller in mobile telephony). This can be separated into a dedicated device known as a Remote radio head (RRH). Power amplifier (PA) Amplifies the signal from TRX for transmission through antenna; may be in.
