Viavi Solutions Introduces RF Monitoring for Heterogeneous Networks

Viavi Solutions 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.

As a highly scalable solution, 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.

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.

Where C-RAN offers network and operational efficiencies, it also creates an opportunity for mobile service providers to improve quality of experience by proactively monitoring the spectrum used by subscribers, and performing proactive maintenance and remote troubleshooting of service-affecting issues like RF interference in a more effective way.

In addition, CPRIAdvisor increases RF visibility by performing continuous monitoring of the mobile spectrum. This allows remote access to expedite maintenance and problem resolution.

“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,” said Jessy Cavazos, Industry Director of Test & Measurement for Frost & Sullivan. “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.”

“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, VP and GM, Converged Instruments and Virtual Test, 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.”
