Similar to cellphone a-gps with a supplemental unified NLP (network location provider), but beefed-up on a large-scale. This should provide more emitter sources, whitelisting and blacklisting, and dedicated software to help discover bad or rogue emitters.

I’m going off the graphic guessing the “detectors” continuous scanning contributes into a database that users will then subscribe on to; instead of the cellphone makeing the self-processing decisions in NLP software.
