This is good because it’s a very universal band but it would probably be better to use higher frequencies such as the 2.5 GHz band or C band. The reasoning behind this is that C-band frequencies are physically smaller radio waves and therefore are transmitted with higher gain from the same physical antenna. It also makes the hardware that needs to go on the actual satellites smaller because it’s a higher frequency.

The problem is, at least doing it on C-band would not work for older devices, because devices only started getting C-band fairly recently, where they’ve had 1900 MHz for years and years.
