Probably this isn't technically possible but here is a possible way to collectively authenticate cell towers:
A service which receives information from an app reporting which cell towers are in range of the phone. The server triangulates the positions of cell towers and updates users about their authenticity.

- mhb 7y agoI don't understand how those work but they seem different from what I am suggesting. I am saying to use the strength of the cell tower signal received by many phones in order to detect where authentic cell towers are.
