Sounded like it was analog cell phone stuff. From: Chuck McCown Sent: Thursday, January 21, 2016 7:03 PM To: af@afmug.com Subject: Re: [AFMUG] OT TV show review
They were trying to figure out where a person was based on pretty sketchy data. They knew which cell site and antenna but it could have been off of a back lobe. The podcast went over this stuff multiple times. Truly ad nauseam.

We used to just run an rf call trace in the switch and it would tell us every cell a person went through, what time, and the current cell they were on. It was pretty easy to track their path. Once we got to cdma with rake receivers and the phones talking to multiple sites at the same time, it became easy to pin-point the location based on the rx sig at each cell. The first cdma system I did this on was in Salt Lake on the Cricket network. Some drug dealer they were trying to find. We got it down to like a 2 block radius and they found him.

I binge watched "Making a Murderer" and enjoyed it, err, perhaps enjoyed is not the correct word. Was fascinated by it and the horrible way the system treats those without resources. Similarly enjoyed the "Serial" podcast series. "Undisclosed" not so much. Got terribly tedious when going over cell phone tracking technology that was from 20 years ago.
