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…

Introduction to Interference Hunting

In this white paper, we will explore the topic of interference hunting beginning with a broad overview of the topic and then leading to a more practical discussion on the different types of interferers, analysis of interferers and the tools that are often used in the field to perform interference hunting.

Detecting & Locating Interference from Bidirectional Amplifiers

Oscillation caused by insufficient path loss between a bidirectional amplifier’s (BDA) donor and serving antennas is one of the most common and most serious forms of interference in cellular networks. This white paper provides a general overview of how BDAs work, the conditions leading to oscillation, and practical information for identifying and locating oscillating BDAs.

Identifying and Locating Short-Duration Interferers

The ability to efficiently detect, analyze and locate sources of radio-frequency interference has become increasingly important in modern wireless networks. Unlike constant or near-constant sources, so-called short-duration interferers can only be detected for brief periods of time and therefore special tools and techniques are often required when searching for these types of signals.
