Interference Hunting in 5G Networks

The tools and techniques used in interference hunting have remained largely the same across previous generations of cellular technologies. Differences in modulation, bandwidth, and frequency bands for 5G networks will however require substantial changes in how interference is detected, located, and resolved in 5G networks. This webinar will provide a short overview of pre-5G interference…

Antenna Basics

This white paper describes the basic functionality of antennas. Starting with Hertz’s Antenna model followed by a short introduction to the fundamentals of wave propagation, the important general characteristics of an antenna and its associated parameters are explained. A more detailed explanation of the functionality of some selected antenna types concludes this white paper.

Evolving Challenges in LTE / Cable Interference Issues

Over the last year, awareness of LTE/cable-related interference issues has grown substantially in both the cable and the wireless/cellular industry. This white paper discusses the results of continued field trials and studies in the area of LTE/cable interference and presents information regarding ongoing LTE developments that may have an impact on cable systems such as…
