I think that would be a stretch. Getting laser to penetrate even 1 km if
atmosphere is tough, and there is quite a bit more of that going
straight up.

An o3b terminal is an identical pair or motorized, tracking 1.8, 2.4
or 3.0 meter sized dishes. Make-before-break connection. There are
some good videos online illustrating how it works.

If the satellite isn't in geo-synchronous orbit then how do you
stay locked on to the signal? Do they have a constellation of
satellites?

O3B altitude is 8062km. At that distance, it takes light
about 27ms to travel. Multiply that by 4 (CPE -> Sat ->
Gateway -> Sat -> CPE) and add a couple ms for frame
processing, and you’re at 110ms latency to the provider.

What kind of latency are we talking? Very interesting stuff.

The greatest thing currently happening in satellite
telecommunications is not more geostationary ka-band capacity,
but the market pricing in wholesale that has happened due to
o3b. For locations anywhere below 45 degrees latitude o3b
provides end to end trunking at a lot less latency, and lower
prices then geostationary systems. Viasat and other owners of
geostationary capacity have been required to drop the monthly
recurring prices for wholesale transponder capacity.
The big difference being that an o3b terminal is too expensive
by far for an end user, it would be typically used by a medium
to large sized Wireless ISP using point-to-multipoint
technology for the individual customers. For example a WISP on
a pacific island nation state that has no submarine fiber access.
