Serval project

The Serval project is a project financed by the Shuttleworth Foundation, as well as various other organisations and accepting individual donations. The project aims to provide infrastructure for direct connections between cellular phones through their Wi-Fi interfaces, without the need of a mobile phone operator.[1][2][3] The project allows for live voice calls whenever the mesh is able to find a route between the participants. Text messages and other data can be communicated using a store and forward system called Rhizome,[4] allowing communication over unlimited distances and without a stable live mesh connection between all participants.

The Serval project includes a collaborate mapping application[5] intended to support disaster relief and recovery efforts. A "mesh extender"[6] is being developed, which establishes a short range Serval mesh over WiFi and joins it with other more distant meshes by linking to other mesh extenders over packet radio operating in the ISM 915Mhz band.

Serval is currently distributed as an application for the Android platform through various stores and repositories or directly from the project website. The application may be shared directly from one device to others nearby over WiFi or Bluetooth. Serval is Free software, its components distributed under GPL licences.
