The progress of 5G new radio (NR) standardization and anticipated deployment of 5G services in both C-band and Ka-band has motivated many coexistence studies for cochannel spectrum sharing with incumbent fixed satellite service (FSS) operators. The use of proposed 5G antenna and propagation models in different urban and rural deployment scenarios impacts the definition of coordination and exclusion zones used to foster coexistence. This chapter analyzes the effect of spatial antenna gain variation and different propagation models on the shape of the coordination zones around FSS Earth station (ES) receivers.
