Comment Better Cannon meet improved Wall (Score 2) 105
I believe this whole outcry is quite stupid. It has quite a "simple" technical solution.
1. Crowdsource the position and coordinates of "legal" cell tower antennas. It's not hard, they are visible . If it is possible to have "OpenStreetMap" I do not see why it cannot have a layer called "OpenCellSites". Just like Waze
2. Write an App, or include it in the firmware that keeps the cellphone from answering siren calls from any antenna not in the list.
Stingray is not a problem if you simply do not answer its call.
I know #2 maybe difficult if it is in the firmware inside radio module. If that is the case then I foresee an industry of open source radio modules with a "veto" signal that tells the cellphone when it is hearing a "better" antenna and asks for permission to change. It it does not receive permission, it is forbidden to switch.
Just My Idea.
