Viavi Solutions has launched CPRIAdvisor, a remote RF spectrum monitoring system that addresses a wide range of antenna deployment options in heterogeneous networks.
Developed in partnership with tier one mobile service providers, it offers the ability to monitor and troubleshoot RF conditions around the clock for any cell site with fiber fronthaul, said Viavi. CPRIAdvisor can support a macro cell with a smaller number of fronthaul fiber 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 per cent in terms of time and cost compared to current practices in place for monitoring and troubleshooting, claims the company.
According to Viavi, to stay ahead of 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. In C-RAN, base band units (BBUs) are co-located at a remote facility, and connected via fiber links – based on the Common Public Radio Interface (CPRI) or Open Base Station Architecture Initiative (OBSAI) standards – to a substantial number of remote radio heads (RRHs) spread around the network.

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.

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.
