The Common Public Radio Interface (CPRI™) is the successful industry cooperation defining the
publicly available specification for the key internal interface of radio base stations between the Radio
Equipment Control (REC) and the Radio Equipment (RE). The Parties cooperating to define the CPRI
Specification are now encompassing Ericsson, Huawei, NEC, Nokia Siemens Networks and Alcatel-
Lucent. Nortel contributed as member of the CPRI cooperation to CPRI Specification versions 1.4, 2.1,
3.0 4.0 and 4.1 and left the cooperation in December 2009
