Webinar Series #1: The Practice of Interference Hunting – The Basics

Radio interference affects our ability to communicate and is a big problem.  Learning how to identify interference, the sources and the solutions is getting a lot of attention in recent years. This webinar discusses radio interference and a basic understanding of why it is a problem, what to look for and adverse effects on radio…

Webinar Series #2: Wireless Interference: Measurements, Common Problems, & Solutions

Finding interference, making the measurement and interpreting the results, are key to successful RF interference hunting. Finding offending signals takes time, patience, and knowledge. It is important to use the right measurement tools to get fast and accurate results. And in many cases, identifying and resolving an interference problem, can have both a technical and…

Webinar Series #3: Wireless Interference: The Art of Interference Hunting – Tips and Tricks

The Art of Interference Hunting – Tips and Tricks There are good radio signals, and there are bad radio signals, often called interference. How do you know? There are many ways to find radio interference such as Intermodulation, multipathing, PIM and radio noise, to name a few. This webinar will look at the science, and…

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…

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. This paper…
