Hong Kong protestors use smartphone app
 

Student protestors in Hong Kong are communicating with each other by using a smartphone app called FireChat.

FireChat by Open Garden is an app that lets people communicate with each other without needing a cell network.

It is able to do that because it can make use of Bluetooth, which has a range of about 200 feet of anyone else using the map.
