Industry leaders cooperate to bring increased efficiency to base station market

Date: Wednesday, June 18 2003
Ericsson, Huawei, NEC, Nortel Networks and Siemens today announced the creation of a new industry cooperation, CPRI - Common Public Radio Interface, aiming to define a publicly available specification for the key internal interface of radio base stations.

The CPRI industry cooperation enables base station manufacturers to focus their research and development efforts on their core competencies and to buy selected radio base station subsystems. Key benefits are faster development when introducing new technologies
and allowing base station manufacturers to offer a wider portfolio of products to the operators with shorter time to market. The operators will benefit from a broader choice of products and more flexible solutions, improving the efficiency of network deployment.

The founders of CPRI are committed to open up a ompetitive mobile network element component industry and will make the CPRI-interface openly available for the benefit of the wireless industry. The CPRI-initiative complements current activities in existing standardization organizations (for example, 3GPP/3GPP2). The interface developed will be used for Radio base station products in mobile systems.

The CPRI-specification is planned to be available 2003, with the objective to introduce compatible products on the market by the end of 2004.

CPRI cooperation is now working on the inclusion of new features like further line bitrates and GSM support, which will be published in new versions of the CPRI specification in due time.
