The Thought Emporium just put out a video on Nebula (should be up on their YouTube channel soon) about this. This is a huge part of why every guide out there tells you to leave your phone at home when going to a protest, or at a minimum turn it off before you get there and only turn it on when you are at least a few blocks away. A burner phone is an option of course but that’s an additional expense and you need to plan for it.

Off and in a faraday bag—along with your wallet. Leave your smart watch at home.

Faraday bags are a big deal nowadays.

iPhone and Android both continue to broadcast BTLE and possibly mobile depending on model while off for hours for Find My features.

While the BTLE beacons should be anonymous, very few things actually are to the right adversary.

Also, many devices with wifi broadcast a list of saved networks whenever looking for a network to join, or did at one point anyway. Useful for people to know who might otherwise be using xfinitywifi or similar.

Right, my keys have a fob. Good catch!
