Identifying passive intermodulation

January 12, 2017 | by Yunuen Wagner

How does passive intermodulation differ from external interference? This article examines the differences and sheds some light on best practices that help field engineers to distinguish one from the other easily. As switching the site off is not always feasible, could the TX power be varied?

Smart macro network enhancements: 4×4 MIMO (part 2)

December 29, 2016 | by Arnd Sibila

The various macro network enhancements available today offer a cost-efficient and smart approach for capacity increase in mobile networks. In part 1 of this series, we provided an overview of the hardware-related capacity enhancing features and discussed carrier aggregation (CA). Now we will discuss higher-order MIMO antenna configurations, particularly 4×4 MIMO.

Evaluating visual quality and video MOS based on subjective perception

December 21, 2016 | by Jens Berger

How do you measure video quality as perceived by end users? The video’s actual visual quality is only one of many factors determining customer satisfaction with the service; other determiners include the service’s structure and the user’s experience and expectations. For real field video quality measurements, reference measurements are necessary.
