Satellite Link Emulation
Application Notes
Satellite links are casting another type of challenge for the simulating of radio link conditions, compared to the terrestrial and cellular communication links. The main differences in the NTN and satellite links are the much greater delay, bigger amount of frequency error, mainly in the form of a Doppler effect caused by the movement of the satellites, and the bigger path loss, when signal is propagating through the atmosphere long distances from ground to satellite and back.
This application note showcases how the Keysight testing environment can be utilized to overcome these abovementioned challenges while developing and deploying the 5G NTN solutions. The Keysight portfolio is utilized, in the form of signal generators, network analyzers and PROPSIM channel emulation platform.
