Radiocomp has developed the world’s first protocol-agnostic remote radio head (RRH) for the mass deployment of Long-Term Evolution (LTE) infrastructure, according to the company. It uses PMC-Sierra’s PM7832 BRIC-2 interface controller to implement a unique multimode RRH platform that supports both CPRI (V2.1, V3.0, V4.0) and OBSAI RP3-01 V4.0 protocols. The benefits of protocol-agnostic RRHs include simplified logistics and greater production volumes, leading to lower cost of ownership for carriers.

The two-port PMC-Sierra PM7832 BRIC-2 termination device fully supports the CPRI specification for wireless basestation interconnect, making it possible for OEMs and ODMs to offer all defined RRH network topologies with a standard digital interconnect for distributed basestation systems. The BRIC family accelerates the adoption of distributed wireless basestation architectures, reducing capital and operational expenditures for carriers, according to PMC-Sierra. It also supports multiple air interfaces like WCDMA, cdma2000, TD-SCDMA, and WiMAX over CPRI with a single interface solution. And, it reduces customer development and bill-of-materials costs as well as the qualification cycle, the company says.
