Signal Strength:
a project to advance mobile democracy


Signal Strength is a project to advance mobile democracy. It consists of modules for ad-hoc social networking that let people in an urban area interact offline, leveraging their mobile phones for untraceable communications.

This is a hack to your existing cell phone that adds another radio to extend the range and allow you to connect peer-to-peer. This works completely independently of your cell phone provider.
