5G site testing and troubleshooting

November 19, 2019 | by Peter Busch

Commercial 5G rollout is happening, and the rate of deployment of 5G non-standalone (NSA) sites steadily increases. Each new installation needs to be verified to ensure correct network performance and quality of service. 5G site testing requires specialist mobile network testing solutions that meet the RAN architecture’s new demands, including over-the-air connectivity and KPIs.

Network Performance Score: Templates for easy support in all products

August 28, 2019 | by Simon Allemann

The Network Performance Score (NPS) delivers a scoring mechanism that allows a very efficient and reliable comparison between operators in a market, and between different measurement campaigns in regions and countries, or before and after the deployment of new technology or software. Learn about the easy-to-use NPS templates in Smartbenchmarker.

Testing 5G QoE: Defining and measuring 5G QoE test cases (part 2)

April 3, 2019 | by Jeremy Carpenter

Without knowing the underlying service and device requirements, network quality engineers do not know what aspects and metrics to treat as important KPIs. How do you define and set up quality of experience (QoE) test cases for new “user” experiences such as for sensors in an industrial IoT deployment?

Network Performance Score: Initiate improvements with a QoE-centric score

January 17, 2019 | by Arnd Sibila

The Network Performance Score (NPS) is a QoE-centric score based on the harmonizing and integrative scoring methodology for end-to-end QoS benchmarking and scoring published by ETSI. The NPS integrates the main KPIs of the most popular services into a single score that describes network performance from a true end-user perspective.
