In the last decade, worldwide consumer demand for cellular services has driven network operators to strive for better network coverage and within that coverage footprint, better network capacity. Since more than 80 % of cellular traffic comes from inside a building, in-building coverage, and in-building capacity have become a focus of this effort. In addition,…
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…
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…
This white paper explains the specific field level and key performance indicators that impact the performance and optimization of an LTE network. In order to have good end-to-end performance, each and every performance indicator needs to be optimized. While a single KPI can affect the user experience in a specific context, true performance management is…
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…

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…
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.
