A base transceiver station (BTS) or a baseband unit [1] (BBU) is a piece of equipment that facilitates wireless communication between user equipment (UE) and a network. UEs are devices like mobile phones (handsets), WLL phones, computers with wireless Internet connectivity, or antennas mounted on buildings or telecommunication towers.
Base station architecture evolved from all-in-one base stations, through Base-Band Units (BBUs) and Remote Radio Heads (RRH), to C-RAN architectures where equipment located at the cell sites Remote Unit (RU) or RU + Distributed Unit (DU) connects via fronthaul network to centralized baseband locations – Central Unit (CU).
In this architecture the radio function unit, also known as the remote radio head , is separated from the digital function unit, or baseband unit (BBU) by fiber. Digital baseband signals are carried over fiber, using the Open Base Station Architecture Initiative or Common Public Radio Interface standard. The RRH can be installed on the top of ...
If the template has a separate documentation page (usually called "Template:template name/doc"), add [[Category:Map templates]] to the <includeonly> section at the bottom of that page. Otherwise, add <noinclude>[[Category:Map templates]]</noinclude> to the end of the template code, making sure it starts on the same line as the code's last ...

The purpose of CPRI is to allow replacement of a copper or coax cable connection between a radio transceiver (used example for mobile-telephone communication and typically located in a tower) and a base station/baseband unit [3] (typically located at the ground nearby), so the connection can be made to a remote and more convenient location.
