> 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.
yeah there's some truth here. from what i understand, the radios that give the best "imaging" are also the least resilient for data -- you need basically line-of-sight. and 5G did have some optional ULF "add-ons" that basically never got used because the tradeoffs for speed to signal integrity were poor.
it won't start as a mass deployment -- just focused on stadiums, airports, government buildings, etc.; maybe some authoritarian states will attempt mass deployments, but the cost will be an obstacle. also, my read is that western telcos aren't interested in owning a surveillance tool because they know their governments won't let them keep it.
hopefully 6G won't be the end of physical privacy. but it will prototype the end of physical privacy -- and i think it will end up being just a matter of time from that point on, unfortunately.
I just dont see the benefit, unless you are installing a 6G device in every room of your house.
Which is probably the target case here. 4G had light adoption by smaller telcos, 5G has some self installable repeaters, but most of the plans for 5G to spread to self installed / class license hardware were all vapourware. 6G might have some backing pushing them into trying to find more ways to sell 6G devices, and having put up a bunch of 6G certified (but class license only) devices in your home, it would be cool if you could see some biometrics, and hook the system into home automation for surveillance and determining whether the lights go on.
But without that in home capability, and massive spread of deployed devices I just dont see the surveillance utility. Especially if your town has lots of awnings and trees.
