Re-creating satellite radio links to test non-terrestrial network (NTN) performance requires simulating operational environments to anticipate potential integration issues such as signal strength, frequency errors, and delays caused by satellite movement. Simulation provides a controlled environment to test and validate various aspects of the integration process. Validating performance ensures that the network meets performance requirements and provides seamless connectivity to users.
Integrating satellite connectivity into cellular networks for 5G NTN requires a comprehensive emulation solution defining satellite orbit parameters and creating scenarios for channel emulation. Channel modeling tools aid in creating standard and user-defined channel models, crucial for system testing. The central components include a channel emulator with cellular and satellite network models and a physical and protocol decoding analyzer. Also included are real base stations and cell phones, or a 5G wireless network emulator simulating a full cellular base station. Together, these components ensure reliable and high-quality 5G NTN service.
