Physics:Common Public Radio Interface
The Common Public Radio Interface (CPRI) standard defines an interface between Radio Equipment Control (REC) and Radio Equipment (RE).[1] Oftentimes, CPRI links are used to carry data between cell sites and base stations.
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 (typically located at the ground nearby), so the connection can be made to a remote and more convenient location.[2] This connection (often referred to as the Fronthaul network) can be a fiber to an installation where multiple remote base stations may be served. This fiber supports both single and multi mode communication. The fiber end is connected with the Small Form-factor Pluggable (SFP) transceiver device.[3]
The companies working to define the specification include Ericsson AB, Huawei Technologies Co. Ltd, NEC Corporation and Nokia.
