How system design enhances the quality and reliability of measurements

Analyzing quality of experience (QoE) and quality of service (QoS) is like shooting at a moving target: in constant flux and affected by a myriad of variables – both known and unknown. Undeniable key factors affecting end-user experience, however, include the network (e.g. the capacity), the location (i.e. the placement of the device, e.g. indoors or outdoors, stationary or moving,…

VoLTE is real, VoLTE is now – the latest measurement results

In early 2015, the first operators enabled Voice over LTE (VoLTE) for their customers in Europe. This requires LTE coverage, a VoLTE-capable phone and – at least in the first months – a dedicated subscription. Today, LTE coverage is widely available and state-of-the-art devices support VoLTE natively. Now is the time to answer some questions: Does VoLTE improve telephony for…

Cut costs and save time benchmarking at remote locations

Say, you’re a field engineer working for a service provider or mobile network operator, and you’ve just been assigned to conduct an ad hoc drive test campaign to analyze voice and data services. The location of the networks to be verified and benchmarked, however, requires you to take a plane and rent a car locally. In most cases, a costly…

Collected information is only as good as its assessment and management

When it comes to operational efficiency, a mobile network testing system’s management and usability are equally important as its reliability and accuracy. Say, for example, when monitoring and optimizing network performance and service quality. A continuous stream of the most accurate data is imperative. But the collected information is only as good as its assessment and management. A smart monitoring…
