<p>Yes. The cell size is ~20 km</p>

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.
<br>
Otherwise, it would be too complex, I guess.
