Industry leaders releasing the new eCPRI Specification for 5G – eCPRI V 2.0 with additional functionality for interworking

Date: Friday, May 10, 2019

CPRI, the Industry Initiative developing the Common Public Radio Interface for front-haul continues to evolve: CPRI Cooperation is releasing a new version of eCPRI Specification. The new specification will enhance the support for the 5G Front-haul by providing functionality to support CPRI (7.0) over Ethernet allowing for CPRI and eCPRI interworking.

Following the successful program to enhance the CPRI Specification to support novel Radio Access Technologies, increasing capacity demands as well as efficient front-haul, Ericsson, Huawei Technologies, NEC and Nokia releases the updated eCPRI specification April 12, in addition to existing specifications, to enable more flexibility for operators expanding their front-haul networks.

The eCPRI V2.0 specification offers eCPRI – CPRI interworking features e.g.

Extends eCPRI flexibility for fronthaul transport between eCPRI nodes and CPRI nodes
Minimize bandwidth requirement by intelligent CPRI mapping
Enables co-existence of new and legacy equipment in the same Ethernet based front-haul networks

In addition to the new eCPRI 2.0 specification, the work continues to further develop the existing CPRI specifications to keep it as a competitive option for all deployments with dedicated fiber connections in Fronthaul including 5G.

CPRI Specifications will be openly available for the benefit of the wireless industry. Key benefits for Network Operators are the availability of a wider radio base station portfolio with adaptability to all deployment scenarios and a shorter time to market. The CPRI Specifications enable base station manufacturers and component vendors to focus their research and development efforts on their core competencies.

The CPRI Initiative complements current activities in existing standardization bodies. The interfaces developed will be used for radio base station products in mobile systems.
