CommScope, Ericsson Complete CBRS Equipment Interoperability Tests
Thursday, April 12, 2018 | Comments

CommScope and Ericsson completed interoperability testing of their Citizens Broadband Radio Service (CBRS) equipment, one of the first successful interoperability tests using the Wireless Innovation Forum’s release 1.2 specifications.

The interoperability test confirmed that CommScope’s spectrum access system (SAS) and Ericsson’s radio infrastructure with CBRS spectrum support will work together as part of a CBRS network. The SAS and CBRS device (CBSD) interoperability testing used a battery of scenarios to verify that both products meet governmental requirements and industry protocols, as well as CommScope’s and Ericsson’s respective quality standards.

“CommScope’s team of architects, developers and engineers have been building an industry-leading SAS for nearly two years,” said Tom Gravely, vice president of research and development, network solutions, CommScope. “Completion of interoperability testing with a major radio equipment provider such as Ericsson validates our SAS design and readies us for commercial deployment.”

In a CBRS network, a SAS and CBSD work together to ensure that the appropriate wireless signals are transmitted and received between the core network and end-user devices, while managing interference. An environmental sensing capability (ESC) works with the SAS to identify the wireless signals of incumbent users to avoid interference from CBSDs. CommScope is one of four ESC operators conditionally approved by the FCC to provide SAS and ESC services.

“Ericsson offers a comprehensive portfolio of CBRS network solutions that will help operators of all sizes deploy in this spectrum quickly and successfully,” said Paul Challoner, vice president of network product solutions, Ericsson. “Additional milestones need to be reached for CBRS to become a reality, but we are pleased to complete interoperability testing with CommScope as part of the developmental process.”

The CBRS band is made up of 150 megahertz of 3.5 GHz shared spectrum, which until now has been primarily used by the federal government for radar systems. The FCC has authorized shared use of the band with wireless small cells.
