[talk-au] Nokia to add radar to phones?

[John Smith]

Nokia have a prototype which they added radar, like the police used to
use till they upgraded to lidar, I wonder how useful something like
this would be in combination with other sensors and GPS etc to produce
more accurate location information...

Towards the end of the clip they show someone walking to/away from the
phone and the phone displays the speed and direction of the person
also...
