Part 3 of the Evolution of Fronthaul Networks (read Part 1: Intro to Fronthaul and Part 2: Fiber Deployment in Wireless) In parts 1 and 2, I described the overall radio access network architecture and best practices for deployment at physical layer which is primarily fiber for the links between the base band unit (BBU) […]

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 […]

Spectrum, the most valuable asset for a mobile service provider, is increasingly crowded and stretched.  New applications and services depend on cleaner and wider RF channels.  No longer just a matter of coverage, spectrum like the rest of the network, is strained for capacity.  Current 4G services add more channels, wider channels, and more aggregation […]

As service providers continue to grow their RF network footprints, they are under tremendous pressure to reduce deployment time to meet constant network demands and reduce OpEx. Fiber to the antenna (FTTA) sites offer significant coverage and capacity benefits, but at the same time this solution creates some challenges for the base station deployment teams.  […]

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 […]
