Mobile misuse the spectrum that they have. They shouldn't get satellite bands and especially not sub 700MHz.
The trade association for mobile operators, the GSMA, has taken up arms in support of its members' campaign for three areas of spectrum at the World Radiocommunication Conference, currently being held in Geneva. The organisation is looking to nab the L-Band, sub 700MHz (including 470-694), where it will be taking on the TV …
That's part of the amateur radio spectrum in ITU regions 2 and 3 while Great Britain also has a small part of the 9cm band although it's in ITU region 1. In the US (ITU 2) we are permitted to emit 1KW from 3300-4000 Mhz. Is front end overload an issue at these frequencies?
How do you stop mobile phones from not operating anywhere within, say, 15km of a satellite ground terminal?
Sharing sat comms band with fixed point-point links is feasible because you know where they are and they don't go for a wander.
How are you going to control mobiles? Have them drop C-band based on a GPS map of potential hazards? Who pays up if some phones and/or software updates starts to cause problems? How do you force out updates to all such phones if/when the licensing for sat comms changes, or is this just a land-grab to force others to pay to change equipment in order that GSMA members can profit?
