This video explains the basic technical principles behind Passive Intermodulation (PIM), why PIM is an issue in wireless communications, and how to test PIM in the field.
This webinar uses a real case study from the first pervasive 5G network in Europe to examine the importance of site acceptance testing, identify the various deployment scenarios and define an efficient methodology to test the associated KPIs to ensure delivery of QoE to the 5G end user.
The rollout of 5G NR will initiate a worldwide deployment in an unknown radio environment where unwanted transmitters can degrade end-user QoE and in some cases cause outages of critical services. Prior to deployment, operators need to ensure the radio environment is free from interference by conducting spectral clearance and interference hunting. This webinar defines… Read more »
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… Read more »
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… Read more »
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… Read more »
Webinar replay from Dr. Jens Berger, Senior Director Applied Research and Arnd Sibila Technology Marketing This webinar presents: Telephony services overview Quality of experience for telephony services Speech quality: how to measure automatically? 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… Read more »
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.
