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 […]

Mobile Operators face business challenges every day that often start with their biggest asset – the network. These challenges are due to massive non-uniformity, constant change in subscriber behavior, and surging demand for bandwidth-intensive services. For example, consider the demands at a train station – a train pulls up, 200 people get off and they […]

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 […]

The American football championship is one of the largest sporting events in the U.S. with more than 100,000 attendees. Most fans have mobile devices, and the bandwidth demand for uploading and downloading multimedia poses a huge challenge for network service providers. In a sign of just how much investment it requires to be ready for […]

Paul Gowans, a seasoned mobile network and service expert at Viavi Solutions, will be presenting on voice-over-LTE (VoLTE) at a conference next week where Viavi will serve as a sponsor.  The LTE Voice Summit will be held September 28-30 at the Millennium Gloucester Hotel, London.  The event promotes that its speakers bring together “case studies” […]
