Viavi launches remote RF spectrum monitoring system
01 June 2017 | Jason McGee-Abe
Viavi Solutions has today launched CPRIAdvisor, its remote radio frequency (RF) spectrum monitoring system that addresses a wide range of antenna deployment options in heterogeneous networks.
CPRIAdvisor, which was developed in partnership with Tier one mobile service providers, enables 24/7 monitoring and troubleshooting of RF conditions for any cell site with fibre fronthaul, said a Viavi statement.
It can support a macro cell with a smaller number of fronthaul fibre links; a large centralized radio access network (C-RAN) or distributed antenna system (DAS) with hundreds of fronthaul links. Depending on the network configuration, it can save mobile service providers up to 50% in terms of time and cost compared to current practices in place for monitoring and troubleshooting.
“Mobile service providers are facing ever increasing, ever complex challenges trying to assure quality of experience while keeping an eye on cost containment and workforce efficiency,” explained Kevin Oliver, vice president and general manager of converged instruments and virtual test at Viavi Solutions.
“In order to address this, and support their diversifying RAN with a single solution, Viavi has partnered with Tier-1 mobile service providers worldwide to develop CPRIAdvisor. It’s a welcome addition to Viavi Solutions’ world class portfolio of RF test solutions, including CellAdvisor and InterferenceAdvisor.”
To stay ahead of the continually increasing mobile bandwidth demand while managing cost and efficiency, service providers are expanding and transitioning from a typical distributed radio access network (RAN) architecture to a C-RAN network topology.
Jessy Cavazos, industry director of test & measurement for Frost & Sullivan, added: “As service providers diversify their access networks to expand capacity and accommodate new services like IoT, they need scalable and flexible methods to monitor performance. The ability to use RF over CPRI technology to monitor and troubleshoot the network, while increasing spectral efficiency with a C-RAN architecture, helps mobile operators keep costs in check and preserve QoE.”
