VIAVI Announces the Most Scalable RF Test Solution on the Market

With CPRIAdvisor, mobile operators can efficiently monitor and troubleshoot uplink interference in cell sites

April 20, 2017 — VIAVI Solutions today announced the launch of CPRIAdvisor, which will allow mobile service providers to remotely monitor RF conditions 24/7 for any fiber-to-the-antenna cell site.

With the vast success of CPRI front-haul deployments, and the never-ending growth of mobile data, service providers are expanding from a typical distributed RAN architecture to a C-RAN (Centralized RAN) network topology. In C-RAN, base band units (BBUs) are co-located at a remote facility, and connected via CPRI links to a substantial number of remote radios spread around the network. Where C-RAN offers network and spectral efficiency, it also offers an opportunity for mobile service providers to troubleshoot network issues like RF interference in a more effective way.


VIAVI has partnered with mobile operators to develop CPRIAdvisor, a new RF test solution that takes advantage of C-RAN architecture to offer the following features and benefits:

  • Visibility: Increases RF visibility by performing continuous monitoring of the mobile spectrum and allowing remote access to expedite maintenance and problem resolution
  • Scalability: CPRIAdvisor is based on network probes with RF over Fiber (RFoFiber) technology, and is able to de-map RF components from fiber front-haul (CPRI or OBSAI) with flexibility in port density providing solutions for any type of cell-site. Whether it is a macro cell with a smaller number of front-haul fiber links or a large DAS/C-RAN with hundreds of front-haul links, CPRIAdvisor solution can handle both.
  • Efficiency: Depending on the network configuration, CPRIAdvisor can save more than 50% in terms of time and cost by offering unmatched maintenance efficiencies, and ultimately providing better mobile services and end user experience.

As the market leader in fiber-to-the-antenna testing, VIAVI was the first to market with RFoCPRI support, allowing customers to troubleshoot RF issues from the ground for remote radio based cell-sites. The addition of CPRIAdvisor to the VIAVI RF test solution portfolio offers mobile operators even greater flexibility for monitoring and maintaining cell sites.
