Ericsson, Huawei, NEC, Nortel Networks and Siemens - the parties co-operating in the CPRI (Common Public Radio Interface) industry initiative - today announced the open publication of the specification for the key internal interface in the radio base station. The CPRI specification for this key interface is the first in the industry.
CPRI focuses on a 3G radio base station design that divides the radio base station into a radio and a control part, by specifying one new interface - the only and unique radio driven interconnect point within base stations. This will enable each part of the base station to better benefit from the technology evolution in its respective area.
