Comparing CW and low duty cycle passive intermodulation (PIM) measurements

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… Read more »

Testing passive networks in distributed antenna systems (DAS)

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,… Read more »

NB-IoT: The Need for Scanner Based Testing

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… Read more »

eBook: What you need to know about NB-IoT technology and testing

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.

Remote Radio Heads in Today’s Evolving RAN Environment

Radio Access Networks (RAN) have evolved considerably from mobile access networks of the past and are helping to drive the “densification” of mobile networks allowing mobile operators to keep up with the heavy traffic demands brought on by 4G/LTE. In this webinar, we look at the forces behind the evolving wireless access network and the… Read more »

Understanding and Testing Carrier Aggregation in the Field
