The Serval Mesh




    Mobile phones normally can't be used when cellular networks fail, for example during a disaster. This means that millions of vulnerable people around the world are deprived of the ability to communicate, when they need it most.

    We have spent the past six years working with the New Zealand Red Cross to create a solution. We call it the Serval Mesh, and it is free software that allows smart-phones to communicate, even in the face of catastrophic failure of cellular networks.

    It works by using your phone's Wi-Fi & bluetooth to communicate with other phones in your vicinity. Or even by forming impromptu networks consisting only of mobile phones. Mesh communications is an appropriate technology for complementing cellular networks. Think of it like two-way radio or CB radio that has been propelled into the 21st century. For long-range communications you will still need to make use of cellular or fixed telephone networks
    or the internet.

    This software allows you to easily make private phone calls, send secure text messages and share files in caves, in subways, in the Outback, in Australia or Africa, in Europe or the United States -- even when cellular networks fail or are unavailable.

    You can also keep using your existing phone number on the mesh, which is really important in a disaster when people are trying to get back in contact with each other.

    Our software:
    * Is completely open and open-source; free for all
    * Can be carried and activated in seconds by those who need it when it is needed
    * Is carrier independent
    * Can be installed during an emergency from only one phone
    * Is distributed in nature making the network resilient
    * Can use your existing phone number
    * Encrypts mesh phone calls and mesh text messages by default
    * Can distribute pictures, videos and any other files

    Sometimes back I was able to install it on android 2.3 phone & use it. But this time it does not install on an Android 5.02 lenovo, it did install on an old Samsung S3 but no mode of communication other than blue tooth worked & that only from a very short range. This app is useless for any purpose that it seems to be designed for.

    I've used it, it works well, although it would be nice if you could copy and paste old messages. Install it BEFORE you have a disaster, obviously, but once you have it you can share it to other devices, it has instructions how.

    Wish the app had Ethernet support then I could use an Android TV box to deploy it in my area
