Coverage and performance testing of 5G private networks

July 8, 2022 | by Gregor Tomic

Private networks are becoming more important in various industries that, however, still seems to be in the trial phase with 5G and various use cases. Our experience with recent measurement campaigns shows that we still have a long way to go to meet the targets for latency and throughput in high traffic networks. Read our story to get more information about how to test the quality of private 5G networks.

Dimensioning a mobile network benchmarking campaign

May 12, 2022 | by Nils Posegga

The Network Performance Score is used to benchmark networks against competitors over time and even across country boundaries. Rohde & Schwarz implementation in line with ETSI TR 103559 provides the tools needed for data collection and post processing. But what does the dimensioning of a campaign look like when it has representative and statistically reliable results?

5G site testing and troubleshooting mobile networks

March 21, 2022 | by Peter Busch

Commercial 5G rollout is happening now and more and more 5G non-standalone (NSA) sites are being deployed. Existing LTE infrastructure is being converted into dynamic spectrum sharing (DSS) hybrid sites supporting 5G. An increasing number of private regional 5G networks in standalone (SA) mode are going into trial phase.

Interactivity test: Impact of changing network conditions on latency and jitter (part 5)

February 17, 2022 | by Jens Berger

Data transport latency has become a very – if not the most – important factor in interactive and real-time use cases for next-generation mobile networks. Real-time capability is not determined by how fast the packets are delivered but by which ones are received last. The following analyzes the distance data packets have to travel in mobile network channels when network conditions change.

Testing can make Open RAN a success

January 31, 2022 | by Magnus Hylén

The biggest challenges the industry faces with Open RAN include the interoperability of different elements from different vendors and generating performance levels similar to those of single vendor networks. Extensive testing can help overcome these challenges.

Interactivity test: Distance to server impact on latency and jitter (part 4)

September 28, 2021 | by Jens Berger

Data transport latency is a very – if not the most – important factor for interactive and real-time use cases in future mobile networks. Today the focus is often on maximizing bitrate and transport capacity for fast downloading, but future applications will require extremely low latency for real-time interactions.

How network testing ensures high quality in-building LTE and 5G deployments

August 17, 2021 | by Adrian Maurer

The popularity of app services, particularly video streaming, among smartphone users is expected to result in a 10-fold increase in data consumption over the next five years. Most of today’s mobile data traffic is generated indoors and this trend is set to continue into the future. While indoor use certainly includes users’ homes, in this context it mostly concerns large offices, public buildings and commercial properties.

Understanding and troubleshooting interference in 5G NR networks

July 22, 2021 | by Manuel Mielke

Interference is a complicated topic with manifold root causes and impacts on network performance. So, let's try to simplify the topic of interference by giving it some structure. In our last blog posts about network synchronization we learned a lot about internal interference, which comes from the network itself e.g. due to a lack of time synchronization. Now let's take a look at the second type of interference. It is called external interference.

Measurement examples of live 5G mobile networks that support DSS (part 4)

July 5, 2021 | by Andreas Roessler

The last dynamic spectrum sharing (DSS) blog post examined the test and measurement methodologies for testing 4G Long Term Evolution (LTE) and 5G New Radio (NR) networks that support DSS. The fourth and final post discusses live measurements from mobile networks that support 4G LTE and 5G NR coexistence in the same frequency band.
