The Serval Mesh

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 four 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 to communicate with other phones on the same network. 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 nature makes 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

Recent changes:
0.92
* MeshMS text messages display delivery notifications and timestamps, and only stored encrypted, but are not backwards compatible
* Vastly simplified the connection screen
* Added phone dialler for tablet users
* Our routing protocol has been improved
* The Peer List is more responsive to changing network conditions
* Reduced power consumption in a number of use cases

Cock blocks my wifi (turns it off every 3 minutes) Maybe I'm using it wrong... Maybe this app does what it wants with your WiFi without telling you in real time... Annoying app anyhow... Regardless of potential scenarios of the future... Needs an off button...; made do with uninstall button for now...

Great app for simple communication services The app has changed a lot and really impressed me with how well it functions in offline mode as a private phone network. I'mo sure that more improvements will happen.
