Yes. The cell size is ~20 km

they can only narrow the radio beam so much (probably whatever their
cell size is). They can't change the footprint without changing the
antenna, so unless they have the beam move around in the cell, the
footprint should be slightly larger than the cell size
sometimes there is a lot of data going to one station, but sometims
it's only going to be a trival amount (think ack packets for a lot of
uploads), so they can save airtime by using one timeslot to transmit
to many stations at once.

Oh, that's interesting.

I thought the satellite beamformer only sends data frames to the
appropriate UT. It looks like the given satellite covers the whole
cell at one TX channel.
Otherwise, it would be too complex, I guess.
