CPRI

The Common Public Radio Interface (CPRI) is an initiative to define a publicly available specification that standardizes the protocol interface between the radio equipment control (REC) and the radio equipment (RE) in wireless basestations. CPRI allows the use of a distributed architecture where basestations, containing the REC, are connected to remote radio heads via lossless fibre links that carry the CPRI data. This architecture reduces costs for service providers because only the remote radio heads containing the RE need to be situated in environmentally challenging locations. The basestations can be centrally located in less challenging locations where footprint, climate, and availability of power are more easily managed.

Altera now offers a complete easy-to-use intellectual property (IP) core for building CPRI v4.2 and lower interfaces to speed development time and allow you to focus on product differentiation.
