Observing distant nuclear fusion, before unleashing it locally.
fission != fusion, but yeah
I’ve got some bad news for you about modern nuclear weapons.

Fire-and-forget drones already exist. They are called missiles.
Missiles generally go from point A and then blow up point b. Are there any missiles that leave base, fly around for a bit trying to identify targets, and if they can't identify any targets then return home?
I said that somewhat tongue-in-cheek, but the line between "drone" and "missile" seems to have gotten pretty blurry with the Ukraine war featuring FPV drones holding a hand grenade that are effectively a human-piloted missile.
Some modern missiles can fly around to identify targets, but they can't return home. They can blow up harmlessly if nothing is a target, though. They can also dodge and weave the way FPV pilots do.
Obviously, "drone" has a much more expansive mission profile than "missile."

LOS communications has been around for a long time now in the form of microwave towers. [1] But further, jamming is still doable, just not with a portable electronic device. Stir up some dust and all the sudden coms are down. [1] https://en.wikipedia.org/wiki/Microwave_transmission
Shoot a laser pointer at the receiver and there's a good chance you have jammed the thing.
how do you detect/find the receiver? thats seems to be a problem

#147This section from the marketing blurb doesn't sound too promising: When atmospheric conditions disrupt the light, our adaptive rate and hybrid architecture maintains the connection, with minimal downtime. In the long run, all these wireless technologies (satellite or optical/microwave terrestrial links) will have a very hard time competing with simply laying down some optical fiber.
Some of their use-case they are crowing about on their site cover temporary things: back haul for major-but-temporary events, tethered-drone-mounted units for emergency disaster recover where a cell site is taken out etc. Those are the sorts of things where laying fibre 20km for use for just a day or two just isn't going to happen, but a temporary laser link that you can get up and running in a hour or two would be g…
What kind of data rates and distances are they talking about that isn't served by existing products? For example, you can buy a 20km range, 2Gbps wireless point to point link for a flat $3000 today: https://store.ui.com/us/en/category/wireless-airfiber-ptp/pr...
What they mention in the article is up to 20Gbps, but they'd have to be pretty dang cheap to out compete just buying 10 of the existing options.

#148It’ll go down at the first sign of rain. We’ve been there with microwave internet.
My Monkeybrains connection stays up (albeit with low-to-moderate packet loss) in the heaviest rain San Francisco has to offer. Granted, that's what folks would call light-to-moderate rain... but that's a LOT more rain than suggested by "the first sign of rain".

Elsewhere in the thread it suggests ~$30k for one link. Which is exactly in line with buying 10 of the ubiquiti devices.
But I think you would need 20 of them, 10 on each end? Plus extra install, networking equipment, etc. Which would make Taara significantly better.

The issue is that you can't put 10 of your 2 Gbps wireless links next to each other. You quite possibly end up with 10 Gbps over > 20 km already (not sure about 20 Gbps, but I wouldn't be surprised). The issue is available spectrum, i.e. you can't just setup the link, because the spectrum doesn't belong to you. Not a problem for optics.
