Hello! I read this article by the EFF and was slightly troubled, the public has known that CSSs operated 2G networks but now it is the case that it can be up to 5G. https://www.eff.org/deeplinks/2024/06/next-generation-cell-site-simulators-here-heres-what-we-know
I understand that GrapheneOS will not ping cell towers under airplane mode (thank you for this feature). I am ignorant to how cell towers communicate, do they have any identifiers when a phone connects to them?
I was wondering if it were possible to build our own whitelist of cell towers, but I understand if this is not possible. I agree that protesters should be advised to turn off their phones or leave them at home, but I see value in photographing these events and if possible being able to upload the media to Signal before the device could be taken by the police.
