CPRI
This protocol called Common Public Radio Interface (CPRI) separates a
traditional radio base station configuration into two separate elements:
Radio Equipment Control (REC) and the Radio Equipment (RE). The REC
processes the baseband radio digital information and performs the control
of the Radio Equipment. The RE converts the digital radio information into
radio frequency signals transported over the air interface (antenna). The
REC and RE are interconnected by a point-to-point link. This link carries the
CPRI protocol and is known in the industry as the fronthaul as opposed to
the backhaul that is the WAN bringing the network traffic to the base
station.
The CPRI link can be extended over several kilometers as it uses fiber
optics, in fact it can be deployed up to 40 km although most field
installations at the moment of this writing are below 10 km.
The CPRI standard covers the physical and data link layers only. This
specific focus provides additional development freedom to the various
vendors to implement proprietary functions at upper layers.
