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…
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…

Speech quality under real field conditions and root-cause analysis OTT telephony services as new competition
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…
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…
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.
Arnd Sibila, technology marketing manager, explains the growing importance of video quality in mobile networks, and the limitations that mobile operators face to control this quality that is dependent on the network resources and how these resources are allocated.
In this video, technology marketing manager Arnd Sibila explains how objective methods and algorithms, such as MOS, J.343.1, etc., are used to measure the subjective nature of video quality in a mobile network.
As a continuation of the earlier video, Arnd Sibila explains in more detail how video quality can and should be tested using J.343.1. As a very robust algorithm, J.343.1 takes into account all video characteristics into a single score; e.g., coding, compression, rescaling artifacts, perceived freezing, etc.
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…
