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.

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.
