Interactivity test: Testing service availability (part 9)

September 1, 2023 | by Meik Kottkamp

5G NR is a cellular technology that supports ultra reliable low latency (URLLC) services. Latency and high throughput have become important KPIs and the interactivity test from Rohde & Schwarz can take measurements in the field by combining access to transport capacity (bit rate), transport latency and transport continuity, all in a single test case.

Interactivity Test: ITU-T Recommendation G.1051 (part 8)

May 11, 2023 | by Jens Berger

Data transport latency has become an important factor in interactive and real-time usage of next generation mobile networks. Measuring latency under realistic traffic conditions and quantifying perceived interactivity are important building blocks in network performance evaluations. The new Recommendation ITU-T G.1051 uses Rohde & Schwarz latency measurements and interactivity tests as international standards.

Validating license obligations – converting network scanner measurements into data rates

April 11, 2023 | by Michael Lorenz

“In mobile communications, trust is good but measurements are better,” says Hubert Aiwanger, Bavarian minister for economic affairs, state development and energy. The German state of Bavaria ordered a fourth review of mobile network operator license obligations. The review focuses on how well operators met the minimum data rate of 100 Mbps on federal roads and selected railway lines.

Interactivity test: Dependency of packet latency on data rate (part 7)

January 26, 2023 | 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. Latency is not a constant; it can vary over time but can also depend on data rate and packet stream characteristics. The following analyzes packet latency and its dependency on data rate and packet size in a few example mobile networks.

5G mobile network testing using a passive network scanner (Part 4)

November 1, 2022 | by Corbett Rowell

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)

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.
