Low orbit space relays. You can hit them from high above with what you want to transmit, buffer it there and they can upload it (or download it?) to Earth pretty fast. Having a few hundred terabytes or a petabyte or two in space for storage I think it is pretty doable nowadays.
If they are low orbit then they are moving fast, which means wider radio beams. And if those beams would also hit earth, hogging spectrum needed for final download.
Not if you do the space-to-space transfer with lasers. There's no air to get in the way, after all.
