> ISAC means adding mmWave to 6G (ostensibly for speed, but also) to build a high-fidelity 3d realtime "digital twin" of the real world that can see through walls, owned and operated by your telecom provider.

"See through walls"

There used to be a great video on youtube of a very high power 60GHz signal being blocked by a door. Sad I can never find it. E Band isn't much better.

IIRC the 60GHz radio is being left out of a lot of 5G deployments because the slight benefits don't outweigh the cost.

This is a pretty common thing for mmWave (or near mmWave) to be deployed with massive fanfare and then be slowly phased out of existence. I am decidedly not writing this on a WiGig docking station.

I dont see telcos wanting to constantly broadcast extra mmWave for little to no added benefit, especially not in all directions. Likewise, regulators are going to choke on that. And the class/band license schemes would have to be updated, to remove interference from devices already using those bands as they are about to have a constant background level of interference. E-Band PTP users, of which there are many, wont give up their high capacity links to weird 6G omni broadcasts without a fight.

I tell you what however, having a button you can press that would map the environment for alignment sounds like a maybe use case here. Better than a camera for detecting new obstructions when links go down.

They might also add more bands to the whole automatic MIMO backhaul trick they have been pursuing.

Great. Now you’re telling me the chicken wire embedded in my walls isn’t sufficient, and I’m going to have to go with grounded sheet metal?

Bruce Wayne implemented this almost 2 decades ago in The Dark Knight. EU innovation moving at a snail's pace as usual /s
