P2P Wireless Meshworks and Telephony

  1. Ad-hoc Dark (roast) Network Travel Mug - Travel mug designed for creating ad-hoc “dark” networks for communication along a morning commute using an Arduino and an XBee module.
  2. Aidphone Flybox - box with inmarsat terminal, wifi access point, and GSM basestation to provide internet & mobile phone service to indy journalistsin crisis situations
  3. Ekiga: an open source SoftPhone, Video Conferencing and Instant Messenger application over the Internet.
  4. GNU Free Call is a new project to develop and deploy secure self-organized communication services worldwide for private use and for public administration. We use the open standard SIP protocol and GNU SIP Witch to create secured Peer-to-Peer Mesh Calling Networks
  5. Mesh Potato: a new device for providing low-cost telephony and Internet in areas where alternative access either doesn’t exist or is too expensive.
  6. Open BSC: [1] OpenBSC is a GSM network in a box software, implementing the minimal necessary parts to build a small, self-contained GSM network.
  7. Open BTS: OpenBTS is an open-source Unix application that uses the Universal Software Radio Peripheral (USRP) to present a GSM air interface ("Um") to standard GSM handset and uses the Asterisk® software PBX to connect calls. The combination of the ubiquitous GSM air interface with VoIP backhaul could form the basis of a new type of cellular network that could be deployed and operated at substantially lower cost than existing technologies in greenfields in the developing world.
  8. Open-Mesh [2], Open Mesh is different from other efforts to build local networks in that their direction is not the connection between different nodes separated by larger distance but the extension of existing internet coverage inside buildings, and between adjacent structures.
  9. OpenMesh Project: global project born after the Egyptian blackout
  10. Pirate Box [3] is a self-contained mobile collaboration and file sharing device. Simply turn it on to transform any space into a free and open file sharing network.
  11. Ronja [4] - wireless networking device with range of 1.4km & communication speed of 10Mbps full duplex
  12. ROBIN [5] - open source mesh firmware that can technically run on any device that support Open WRT. ROBIN networks can be managed centrally through the use of dashboards like Surreal (http://surrealwifi.com) and Robin-Dash. forums here: http://robin.forumup.it/
  13. Serval [6] ; the only working mesh solution that uses off the shelf phones and off the shelf unlicensed spectrum and existing phone numbers, and can work with absolutely no infrastructure.
  14. Village Telco [7]: The goal of the project is to render local telephony in developing countries to be so cheap as to be virtually free. Thanks to advances in Open Source telephony software and the dramatic decrease in the cost of wireless broadband technology, we think this is entirely possible.
