When the Government Stops Internet

Imagine a situation where the government or your school stops the internet connectivity and you desperately need to send an emergency message to a friend or family across the city or in different towns.Technology has advanced in such a way that a single off switch on our internet connectivity cant stop communications.We should understand that the, internet is simply an inter-connection of computers( your phone is a computer).
The big question that rises, is. if there is a possibility for us to be connected not necessarily via a telephone line or a public WiFi?.
Yes of course, two computers can be connected via Bluetooth, WiFi, infrared etc.Now if this
network is expanded,(by connecting other computers) its range can extend further with each computer acting as both a receiver and a router.This creates a mesh network in which these computers can
communicate through. One very popular app that has made this a possibility is Firechat .Firechat is a proprietary mobile app, developed by Open Garden, which uses wireless mesh networking to enable smartphones to connect via Bluetooth, Wi-Fi, or Apple’s Multipeer Connectivity Framework without an internet connection by connecting peer-to-peer.
FireChat first became popular in 2014 in Iraq following government restrictions on internet use, and thereafter during the Hong Kong protests. In 2015, FireChat was also promoted by protesters during the 2015 Ecuadorian protests.On September 11, 2015, during the pro-independence demonstration called Free Way to the Catalan Republic, FireChat was used 131,000 times.

In January 2016, students protested at the University of Hyderabad, India, following the suicide of a PhD student named Rohith Vemula. Some students were reported to have used Firechat after the university shut down its Wi-Fi.
I also beleive this app can be of great help to african countries undergoing political instability where the government sees social medias as a treat and plan to shut it down
