5G networks will increase the number of connections from about 4500 per antennae, to about 40,000 per antennae. For 5G networks to function at full effect, they require many closely spaced antennas (the speed of light becomes a lag factor), with precise beam-forming to reduce interference. They will need to track every connected device to within a few centimeters, both for azimuth, and to carefully optimize the amount of power applied to the connection.
So clearly this can be used for detailed tracking. Can it be prevented from being used for targeting?
No end to the list of troubles that can occur once the bad dudes are inside your network due to a single weak link.
