Performance degradation due to asynchronous 5G networks

A measurement campaign quantifying the impact of intermodulation in 5G TDD networks

Critical infrastructure: With the deployment of TDD networks, the mobile network community recognizes the critical importance of cell synchronization and the use of uniform TDD patterns across different networks for the proper operation of mobile radio networks.

Variety of scenarios: Possible scenarios include cross-border situations, interactions between private campus networks and public mobile networks, and accidental synchronization chain breaks or misconfigurations within the mobile network.

Measurement techniques: To quantify the effects of non-synchronized cells and using different TDD pattern in neighboring networks, R&S, in collaboration with TU Dresden and Advancing Individual Networks GmbH (AIN), conducted a measurement campaign using movable networks with full control over all network parameters. This campaign measured the effects on uplink and downlink throughput, mapping these to RSSI/RSRP values received at the interfered site.

Customer benefits: The available quantification is valuable for predicting and assessing potential interference scenarios before setting up and operating a new cell site.
