Inmarsat, Iridium, Thuraya, and Globalstar primarily use L-band.
The early PCS allocations and a few later allocations (1900, 1800, 1700) are also L-band, but there’s good reason not to use them for this, they are already heavily in use all over. Satellite cells cover a large area and you don’t want to collide with a tower using the same frequency.
The 600-800mhz allocations are not great for satellite broadcast due to limiting characteristics of those bands.
So for the 5G bands that would not already heavily be in use and/or aren’t well suited to satellite use, that leaves us C band (3-5ghz), and K/Ku band (mmWave).
