Part 2 of the Evolution of Fronthaul Networks (read Part 1: Intro to Fronthaul and Part 3: CPRI ) As we learned in part 1, fiber deployment permits the placement of RRH’s closer to the antenna. Also known as light radio, this RRH placement has significantly improved the energy efficiency of cellular networks as the […]

The use of fiber in networks of all kinds is increasing by the day. Fiber brings increased capacity, but also carries new, unique challenges and a need for careful, efficient testing and measurement. Where can technicians and engineers find he most current, helpful information about the latest tips and tricks for testing and installation? Well, […]
In just a few short weeks, the Viavi Solutions team heads to 5G World during TechXLR8 in London. Billed as the ONLY global 5G-focused, high-level conference and expo, the show addresses industry-impacting topics related to 5G trials and migration strategies from LTE to 5G. If you are going to the show, we invite you to […]
Interference in cellular networks is one of the most common problems in the radio access network (RAN). As demand for cellular data continues to grow, causing proliferation of RF spectrum and amplifying RAN interference issues, managing user QoE will continue to be a big challenge for service providers. This challenge is further exacerbated by the […]
In this blog we will discuss in brief the benefits of distributed RAN, some of the challenges faced by this new architecture, and how the RFoCPRI solution on Viavi’s CellAdvisor platform is helping service providers to overcome those challenges. Advancements in radio technology (improved power amplifier efficiency, better design and longer MTBF) have allowed service […]
