Ensure successful 5G site testing and acceptance

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.
Application Notes:

Interference hunting in TDD networks

In time division duplex (TDD) networks, the downlink (DL) and uplink (UL) use the same frequency band in different timeslots. When viewing such TDD signals on a conventional spectrum display, it is impossible to differentiate the two as well as any other unwanted signals present in the same spectrum. This makes interference hunting extremely difficult.… Read more »

Prepare your Spectrum for 5G Deployment

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 »

Testing Passive Networks in a Distributed Antenna System

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.

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 »

Wireless Interference: Measurements, Common Problems, & Solutions

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 »
