Common Public Radio Interface (CPRI) v.6.1 IPC
Overview
CPRI (Common Public Radio Interface) is an interfacing standard for high-speed communication of digital radio samples and control data between wireless infrastructure base station inter-modules. MTI’s IPC-CPRI-v.6.1 solution enables the quickest and most reliable deployment of REC (Radio Equipment Controller) interfaces for easy and flexible interfacing to Remote Equipment. It includes all features required to support MC-GSM/LTE/WCDMA/WiMAX standards. MTI’s IPC-CPRI-v.6.1 is a self-contained and fully tested solution compliant with the latest CPRI v.6.1 specification. It builds on or earlier the market leading solutions used today in many eNb field installations as well as in Tier1 DSP ASICs and FPGAs devices.
