Satellite-terrestrial spectrum sharing and interference

The Spectrum Sharing Challenge

Satellite and terrestrial networks increasingly share the same frequency bands, creating complex interference management challenges. Traditional satellite services operated in dedicated C-band, Ku-band, and Ka-band allocations separate from terrestrial mobile networks. However, D2D satellite services must use terrestrial mobile spectrum to connect unmodified phones, and regulators have reallocated portions of C-band from satellite to 5G terrestrial use. This convergence demands sophisticated sharing frameworks that protect both satellite and terrestrial services from harmful interference…
