New "twisted light" fiber optics technology

[ben4372]

I'm just reading this thread a little after looking into 5G. Irving actually started it before my curiosity of 5G. I'm not sure how twisted light is different than the current muxxing, except maybe more compact? I do know 5G might be awesome. A more worldly friend reminds my how slow USA is in catching up. Cars, medicine, tech. I do know that fiber to the home has fallen out of favor with Comcast, and they are reallocating resources to the cities that are going to launch 5G first. Much like they did trying to get ahead of Google fiber. The part that might slow the 5G is the number of cell sights needed to make 5G work. As mentioned, you'll need to be closer to a tower. Turns out some cities are making it expensive to deploy new towers. Same 5G experts also reminded people that 15-25 meg is what most people need.

Snip...
Anything updated in the last 3 years is quite safe. There's a lot of insecure ubiquiti equipment around if people have a bad streak

That's debatable, depending on the hardware that is used.

The newer AF stuff is pretty secure. Most of the rest of it is still rather vulnerable.

UBNT has several very useful and worthwhile product lines (Edgerouter and Edgeswitch(or the Unifi variants), Unifi AP's, and Unifi Video), but they are starting to lose market share in the wireless side. They have over promised and under delivered, and their prices keep climbing. Cambium ePMP and Mimosa Wireless are continuing to whoop up on them.

If you are curious about the bleeding edge of wireless, read this: https://www.zerohedge.com/news/chica...5-milliseconds

I have met one of the wireless engineers that was involved in the McKay Brothers network. Some of the things they came up with are slick.

I've heard that the Tradeworx network took many of their ideas and simply used newer radios and antennas to improve upon it.

In case you were wondering, these aren't built with $150 microwave radios.

This is possible because the speed of light in fiber is actually about 2/3 the speed of light through air.

They don't mention the bandwidth... while we have a 100Gbps circuit from Chicago to the Jersey coast, you can't get that kind of BW on microwave. The HFTs have to focus on segments of the market with limited BW.
