  • All these Wifi for tracking people methods use the channel state information (CSI) that is used to help decode the transmitted data. CSI is obtained from pilot signals that are transmitted as part of a regular transmission. This is done in basically all digital communication standards, so you could do this not just with Wifi but also with 4G or 5G or older mobile communication standards. This is all not very surprising, there is a lot of research in contactless radio based heart rate monitoring, they usually build on radar systems not communication systems though. The buzzword for 6G for all this is joint communication and sensing.



  • For GPS jamming there is research into alternative ground based location services, I’m currently doing research in that area. Interestingly one major problem there is not GPS jamming in hostile areas, it’s truckers using GPS spoofers for their tracking devices, because apparently that happens and it happens far away from any wars. Loss of communication was what I researched before, i.e. how reliable communication links are. For most of the other things you list a regular pilot can’t do much more than someone remotely operating the aircraft from the ground, the pilot is not going outside to fix an engine mid-flight, or hit the landing gear with a hammer until it works again. For autolanding, the whole idea of remote piloting is to not rely on autoland.










  • Honestly, I’m not sure if that really applies to Germany. A lot of downtown areas are kind of dying because they don’t know what to do with the space that is left empty when stores close, but it’s usually not the kind of store you would consider a third place. I suppose those stores drew people into the downtown areas and then people also went to a café or something, but the cafés are still there and people still go there. I haven’t heard much about closures of theatres, museums, libraries and so on. What kind of third spaces are you missing?
