A base transceiver station (BTS) or a baseband unit (BBU) is a piece of equipment that facilitates between (UE) and a network. UEs are devices like (handsets), phones, computers with connectivity, or antennas mounted on buildings or telecommunication towers. The network can be that of any of the wireless communication technologies like , , , , or other .
The , or BTS, contains the equipment for transmitting and receiving radio signals (), , and equipment for and decrypting communications with the base station controller (BSC). Typically a BTS for anything other than a will have several transceivers (TRXs) which allow it to serve several different and dif.

A power inverter, inverter, or invertor is a device or circuitry that changes (DC) to (AC). The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of which were originally large electromechanical devices converting AC to DC.

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.

Solar inverters may be classified into four broad types: 1. , used in where the inverter draws its DC energy from batteries charged by photovoltaic arrays. Many stand-alone inverters also incorporate integral to replenish the battery from an AC source when available. Normally these do not interface in any wa.
