Network Synchronization of 5G networks

The last blog post (Part 3) examined the first challenge of how you can measure and analyze 5G networks passively by analyzing synchronization and broadcast signals. In this article we address the challenge of timing alignment between 5G base stations as this has a large effect on inter-cell interference and consequently user experience.

Interactivity test: Packet delay variation and packet loss (part 6)

Interactivity test: Packet delay variation and packet loss (part 6)

October 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 the average latency at which the packets are delivered, but rather by the latency of the slowest packets. The following analyzes delay jitter and the packet loss in the uplink and downlink.

Coverage and performance testing of 5G private networks

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

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

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)

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

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.
