I'm low key afraid that this stuff is gonna get popular for .mil usage. Line of sight free space optics can be immune to many many forms of jamming. Its usage dots the sci books I've read over the years, but almost always for scary reasons. Here's the Navy today announcing work on AirBorne System for Optical Relay and Broadcast (ABSORB), a (for now) low-cost prototype one-to-many (I maybe mis-inferring what multi-acc…

How is better communication scary for military? The weapons themselves are

Should the military not have internet? If laser based internet is better than satellite or microwave or wireless (I assume the military uses these three). Then isn't that good?

This 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.

It's interesting at 36 to look back at what I think would disrupt connectivity a decade ago: - Google Fiber (it wasn't possible to do it cheaper than incumbents, so it devolved to standard incumbent x why would 40% margin company invest billions to get Comcast's peak profit margin of ~15% profit) - Starry Internet (too expensive to build out, I have it and it's good, but the company certainly didn't scale) - 5G in ge…

> I keep wondering how people make Starlink work, my understanding is the connection degrades then stops then reconnects every...idk, 5 minutes? as the satellites go overhead.

That is not a correct understanding for how the Starlink network behaves today[0]. While I can't speak for using it outside of the U.S., I have not faced any interruptions outside of a few times during very severe weather.

[0] in the early days of the constellation, there were sub-second or a few second drops when there was no satellite overhead. But this dropped off very quickly once the constellation size increased.

When I came to Silicon Valley in the early 2010s and realized that all of the king's horses and all of the king's men could not defeat the scourge that is the US ISP oligopoly even in their own backyards, I knew it was pointless to ever hope for real FTTH in Bay Area markets in the next couple of decades. Wireless solutions have orders of magnitude less bandwidth than fiber, and you can run lots of fiber in a bundle,…

In Silicon Valley, in a neighborhood of $2.5M homes, and thus household incomes on average of probably $600k+. It should be possible to get a fiber rollout, they aren't that expensive. Make a neighborhood ISP, or try and get a municipal ISP.

Wait, "Google X" is now just known as "X"? So there is a separate "X" from Alphabet and "X" from tweet all day guy?

What this means is that in the next 5 years Microsoft will name 3 different things X.

. . . and put them in a box.

The key breakthrough for 5G was allowing ~10x the number of devices to connect to a node compared to 4G. 5G is what allowed the toppling of data caps that was by far the #1 consumer complaint for years. 4G just couldn't handle heavy loads well, so data caps were needed to constrain demand.

Teleco's aren't going to say this out load, but it's the real reason why they were so celebratory about 5G, despite it coming off like just a renamed 4G to the average user.

It’ll go down at the first sign of rain. We’ve been there with microwave internet.

I haven't heard of microwave internet. Any recommended readings?

It’ll go down at the first sign of rain. We’ve been there with microwave internet.

The implication being that you know more about this technology than then people building it and funding it.

At one point we bought a fancy (for the time) microwave link to cover a distance of about 3km. We specifically asked whether it would be affected by weather conditions. We were assured multiple times in the most confident of terms that it would not be a problem, the technology was tested and such eventualities accounted for with various features and failsafes.

The thing proceeded to go down every time it rained, and no amount of tweaking settings, power, phase, polarity or orientation helped. This is the manufacturer/vendor doing the tweaks, mind you, not clueless me (I wouldn’t dream of touching this arcane technology I knew nothing about).

In the end we ditched the microwave and went with a good old copper link which worked without a hitch regardless of the weather.

So since you are, in your own sarcastic way, asking how I know, this is how: from experience. I don’t know about the technology but I do know about when they promise you it will work in the rain.
