There's a whiz-bang-wow factor for free space optics. I'm not sure if
there's any real technical advantage over millimeter wave though. None
that I'm currently aware of.

Seems to me like you're almost always going to be a lot better off
just using 80ghz (or even 60ghz, depending on requirements)... I guess
if you need more than 10Gbps it might make sense, but otherwise, it
seems like playing with this stuff is just going to cause a lot of
unnecessary headaches.

I hope its come along way. we did some and it was awful. auto
alignment had to be turned of because it would sometimes just
start adjusting and go out of alignment like it was having a
seizure. lens fogging was awful. We had one where it would take a
courthouse down roughly the same time every day, finally tracked
it to sun reflection off an aluminum parapet. i had to haul a
truck tarp up onto the roof to cover the parapet to prove it. The
only place for lasers is in flexible glass

Yep...they tried one from a bank building in El Paso to Juarez
back in the late 1990s...22 story building moved too much...we
ended up installing a 23Ghz link but from another location.

I would think now it would be easier to mount the laser in
a gyro stabilized gimbal to account for the movement. In
the 90’s that technology was not affordable. Image
stabilizing cameras exist, gyro stabilized RC helicopters
and drones are commonplace.

I did too. Mexico City. E1 data rate. High rise
buildings. Building movement was a problem.
