Recently, a tier 1 service operator in Brazil was faced with the challenge of assuring that the customer experience for all mobile 2G, 3G, and LTE traffic was top quality during the rapidly approaching Rio Olympics. Prior to the games, they had seen network-wide latency issues which were causing problems with their customers’ call quality, such as slow response times and reduced […]

Today’s dynamic lifestyle-connected customer uses a myriad of services and applications and therefore demands a high level of Quality of Service/Quality of Experience (QOS/QOE) delivered to their mobile phones, tablets, laptops, and other network end points. With Ethernet being a primary transport and congregation point for all this data, it is imperative to assure the […]

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.
