The Left finds out that tracking by cell phone is a sword that cuts both ways.
Before the “Insurrection” (the one where people forgot to bring guns), the smart people at the New York Times knew that cell phone pings could be used to track people with great precision. In a piece called, “How to Track President Trump,” Stuart Thompson and Charlie Warzel described how they tracked one of Trump’s Secret Service agents, by using cell phone technology.
The meticulous movements -- down to a few feet -- of the president’s entourage were recorded by a smartphone we believe belonged to a Secret Service agent, whose home was also clearly identifiable in the data...We could also see other stops this person made, apparently more connected with his private life than his public duties.
The article, written in December 2019, included an aerial map of Mar-A-Lago, and it showed exactly where the Secret Service agent was standing:

Saving Fani Willis
Unfortunately, cell-phone accuracy is being disparaged again -- this time in a futile effort to save Fani’s fanny. Here is an example. A learned Georgia Tech professor (Paul Steffes) has claimed:
“At best, the data appears (sic) to show Wade, who could have been driving around, was within a 9-square-mile area that include Willis’s condo.”
Somehow, we have gone from just “a few feet” to “9 square miles.” That may not sound right to you, but lawyers for the Fulton County prosecutor’s office have already confirmed it: The pings coming from Wade’s cell phone can only place him within a “multiple-mile radius.” I bet some of the J-6 defendants wish they had been told this before they were convicted and sent to the D.C. gulag. Remember, cell-phone pings were the method du jour that put many of them behind bars.

Paul Steffes is neglecting to tell you that you get the 9 mile hit from just one of the local towers, there are others within or near the cell area that also have signal and can be tracked. You get (have) record of three of them and you’ve got better than his 9 miles. Cell phones have to have next strongest backups because the potential exists you might transit into one and need your home coverage there. A very misleading article if you ask me.
In the Navy, I did that and it was called HFDF (High Frequency Direction Finding), and it was always done with a 3 site axis. You recorded the direction each site received the signal, and then crossed them. That “X” of where the (at least) three lines crossed is the transmitting location.
If it’s 1 site, it’s a bearing. If it’s two, you get a general location. Three or more, you triangulate even further down.
