The Common Public Radio Interface (CPRI) is an industry cooperation
aimed at defining a publicly available specification for the key internal
interface of radio base stations between the Radio Equipment Control
(REC) and the Radio Equipment (RE). In the industry the CPRI REC and RE
are mainly known as Base Station (BTS) and Remote Radio Head (RRH)
respectively.
The Open Base Station Architecture Initiative (OBSAI) separates a
traditional radio base station configuration into a Base Transceiver Station
(BTS) and a Remote Radio Head (RRH). The BTS processes the digital
baseband radio information and performs the control of the RRH. The RRH
converts the digital radio information into radio frequency signals
transported over the air interface (antenna).
