  The technology in a radio tower is undergoing dramatic change, which is presenting tough real-world challenges for the crews that carry out the installation work. Riggers, or tower climbers as they’re better known in the US, are finding that as networks become more complex, their role is becoming increasingly difficult. As technicians, riggers perform […]

Centralized Radio Access Network (C-RAN) deployment is a growing trend in the wireless industry. I am often asked what is driving this trend, why some operators are using it more than others, and what are some of the challenges and benefits of C-RAN. In this blog, I will try to capture some of those questions […]

Security Forensics

Another day, another cyberattack. Just as companies were recovering after the WannaCry attack, a number of organizations were hit by Petya… or NotPetya. Name it as you see fit. In a matter of just two months, two devastating ransomware attacks have crippled networks globally. Clearly, security threats are multiplying in intensity and complexity. But what […]

Locating an interference source is nothing short of finding a needle in a haystack. From a service provider perspective, RF interference is much more than a nuisance. If it is not eliminated, it can negatively impact service providers’ CAPEX, and OPEX, and can cause subscriber churn. In a recent survey conducted by Nokia of 20,000 […]

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.  […]

Suddenly, on a Monday morning around 9:30 am, we started to get calls at the NOC of high dropped calls near a strip mall; this continued till 6 pm. Everything was working fine last week; we did not make any changes to the network, the neighbor list, or other RF parameters over the weekend. I […]

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 […]
