The app that lets you chat WITHOUT an internet or phone connection: FireChat uses hidden iOS feature to relay messages:
THIS APP COULD LET US CONTACT EACH OTHER WHEN OBAMA USES THE INTERNET "KILL SWITCH"
- The iOS 7 feature is called Multipeer Connectivity Framework (MCF)
- It creates what's called a wireless mesh, or peer-to-peer, network
- Instead of sending messages using a mobile signal, the free app creates its own network where each mobile on it becomes a 'node'
- This means people in close proximity can message other nodes
- Messages are also sent over long distance by relaying data from one node to another anonymously
