As per my understanding, for terrestrial usage RF spectrum is auctioned by the governments before telecom operators can avail it for commercial purpose. Seems like a logical way to utilise limited resource (example:https://5g.co.uk/guides/5g-uk-auction/).

In contrast, it looks like allocation (by ITU and corresponding national regulators) of the extra-terrestrial RF spectrum for proposed commercial Satellite Megaconstellations is essentially free? Is there any existing licence fee for such commercial operators?

    $\begingroup$ Last time I heard, they seem to be considering the 5GHz spectrum (and even using wifi as medium)? If so then it's indeed (mostly) free. Another choice is mmW, which, although not free, is quite abundant. $\endgroup$ Oct 31, 2019 at 18:58

  • $\begingroup$ @filo notes in response to my other question that "you can carefully reuse the spectrum" due to highly directional nature of intended frequency spectrum but it is still unconvincing considering high number of satellites proposed by SpaceX and its 8 other competitors and as per this blog each satellite beam will be few sq. kms in area on the surface $\endgroup$

  • $\begingroup$ @user3528438 : they seem to be using 10-14GHz (see page 4 ) as pointed out by filo in a separate thread $\endgroup$
