Re: How hard is the approximate localization of a 2.4GHz sender operating in or near an airport?
It's actually quite easy to do good geolocation based only on the SIM, a variety of companies sell such software to the networks."
Yeah it's actually not. As an emt I've had to use such information as part of my job on the regular(comes over mapped on an MDT), and I've seen the magic software at work in dispatch centres. Even using e911, where the subscriber implicitly wants to be found, the info's not great, I can't recall a single instance where it alone would have sufficed to locate a caller/patient.
And near a major airport the info is going to amount to,"if the airport drone is, in fact, using SIM #n, we can confirm that airport drone is at or near the airport."
