With more than 80 % of cellular traffic coming from inside a building, distributed antenna systems (DAS) have become increasingly more popular. However, without a sound testing methodology, these systems can be complex to test. Request your free poster and download the pdf to learn more about DAS and how to test these systems. Posters…
This white paper describes the AOA and POA methods applied to automatic radiolocation of RF interferers from a moving vehicle, comparing their performance with focus on cellular networks in urban areas.
The measurement technique used by a PIM analyzer is CW or low duty cycle. The only traceable device available to independently validate a PIM analyzer’s measurement accuracy in the field is a PIM standard. For this technical discussion, the measurement techniques are explored and explained along with the fact that CW and LDC offer similar…
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…
NB-IoT, (Narrow Band Internet of Things), also known as Cat NB1, is a standard for connecting “things” to the internet through the cellular network. This is a standard focused on machine to machine communications. The range of applications are vast, with key applications including asset tracking, intrusion detection, utility meter reporting, smart parking areas, and…
Cellular wide area network technologies, in particular for security and mission critical use cases and applications, require very high network reliability and availability where proper device testing and also network testing is a must to always ensure the essential quality of service.
