The original and traditional high-cost way of how this is done for MEO/LEO
is exemplified by an o3b terminal, which has two active motorized tracking
antennas. The antenna presently in use for the satellite that is overhead
follows it until it's descending towards the horizon, while at the same
time the second antenna aims itself at where the next 'rising' satellite is
predicted to appear at the opposite horizon, and forms a link to it.
Make-before-break. If anyone has seen photographs in their marketing
material/videos of the Oneweb beta test earth stations in Alaska they are
operating using the same general concept.

Oneweb has clearly positioned their market focus for telecoms and ISPs and
large enterprise end users, because their CPE equipment is considerably
larger, expensive and more power hungry. The beta test sites I've seen
installed on top of a telecom equipment shelter occupy an area
approximately 8 feet long x 4 feet wide including radomes and mounting.

My original thought was this would be more like Client Optimized Roaming
with WiFi access points.

Communication between the client dish or base station and satellites to
transparently move client dish and base station from satellites moving out
of view to a satellite in view.

I read in the Economist that the gen of starlink satellites will have the
ability to route messages between each satellite. Would conventional
routing protocols be up to such a challenge? Or would it have to be custom
made for that problem? And since a lot of companies and countries are
getting on that action, it seems like fertile ground for (bad) wheel
reinvention?
