Nakia wants 6G devices to act as 3D imaging clients, and for network operators to have access to a realtime, 3-dimensional visualization that can see right through walls.
this was literally used as a plot point in one of the batman movies a decade ago to highlight how dangerously invasive tech can be.

> A very exciting innovation that 6G will bring to the table would be its ability to sense the environment. The ubiquitous network becomes a source of situational awareness, collating signals that are bouncing off objects and determining type and shape, relative location, velocity and perhaps even material properties. With adequate 6G solutions for privacy and trust, such a mode of sensing can help create a “mirror” or digital twin of the physical world in combination with other sensing modalities.
