Testing non-terrestrial network (NTN) base stations is essential as NTNs play a crucial role in extending 5G network access ability to satellites. In a lab environment, use a radio channel emulator to simulate satellite communications and channel conditions, such as dynamic propagation, path loss, Doppler effects, and other noises and interference between ground gateways. To simulate a complete wireless communication cycle, engineers must also simulate hundreds or even thousands of user equipment (UE).
Engineers need to employ a robust and scalable software solution to assess the transmissions at the protocol and physical layers to properly manage and monitor the communication between a simulated satellite gNodeB and user equipment in large numbers. This approach enables engineers to troubleshoot wireless connections by verifying base station behavior, evaluating the performance, and identifying throughput delays.
How to Validate NTN Base Stations
UeSIM enables infrastructure vendors, chipset providers and mobile operators to validate end-to-end Radio Access Network performance by emulating real network traffic over both radio and O-RAN fronthaul interfaces.
