Coexisting or Clashing: 5G with Radar/Satellite

With new bands specified for 5G communications systems, there is now an issue of coexistence, which is radar and satellite using the same or similar frequency bands with 5G. Such coexistence can cause loss of capacity in 5G systems, can cause reduction of radar effectivity, and can even damage sensitive front ends in satellite ground stations. In this presentation we discuss new digital twin technologies that can be used for planning and simulation purposes of coexistence effects. We also discuss the use of lab prototyping to predict the impact of coexistence, and the metrics used to measure impact. We also describe methods and metrics for monitoring a deployed network for coexistence conditions. Lastly, we possibilities for mitigating coexistence effects. With these technologies, EM effects can possibly coexist across all domains.
