**[[:content:servalmesh:|Serval Mesh]]** is an Android app that provides [[:content:tech:security framework|highly secure]] [[:content:tech:MDP|mesh networking]], [[:content:tech:VoMP|voice calls]], [[:content:tech:MeshMS|text messaging]] and [[:content:tech:Rhizome|file sharing]] between mobile phones using Wi-Fi, without the need for a SIM or any other infrastructure like mobile cell towers, Wi-Fi hotspots or Internet access. * [[:content:servalmesh:|Serval Mesh general information]] -- download, install, documentation, [[:content:servalmesh:releases:|release history]] *

between Apple iPhone and iPad devices using Apple's proprietary peer-to-peer wireless network. * for the time being, [[:content:servalchat:|Serval Chat]] does not communicate with the [[:content:servalmesh:|Serval Mesh app for Android]] or the [[content:meshextender:main_page|Serval Mesh Extender]] ===== Serval Maps ===== **[[content:servalmaps:main_page|Serval Maps]]** is an Android app that uses [[content:servalmesh:|Serval Mesh]] to provide collaborative, infrastructure-independent, geographical mapping. ===== Serval Mesh Extender ===== The **[[content:meshextender:main_page|Serval Mesh Extender]]** is a hardware device that helps other devices to join and participate in a [[:content:servalmesh:|Serval Mesh]] network. ==== Second-Generation Serval Mesh Extender ==== The [[content:meshextender:2ng|Second-Generation Mesh Extenders]] are the current generation of Mesh Extender hardware, and continue to be under active development. {{:content:meshextender:front_3-4.jpg?200|}} * powered by external USB, 12v/24v automotive and/or solar (with MTTP tracking charge controller) * Integrated LiFEPO4/LiIon/Sealed-Lead-Acid battery charger * Custom-designed injection-moulded housing * Designed to meet IP66 environmental resistance * Integrated "Mesh of Things"/"Internet of Things" I/O port * microSD card for bulk storage (reduced power consumption versus USB) * Wi-Fi access point (for devices to connect) and ad-hoc Wi-Fi (between Mesh Extenders) * RFD900/RFD868 UHF packet radio (up to 4km range line-of-sight, ~200m indoors) * Interface to [[:content:meshextender:externalradios|Codan/Barrett HF Radios]] for very-long-range communications links (support for other radios is also possible) * provides a standard Wi-Fi Access Point for nearby devices (such as smart phones) that do not support Ad Hoc Wi-Fi mode * offers the [[:content:tech:Serval Mesh]] app for Android for download via HTTP so that people can join the [[content:tech:mesh network]] without having previously installed the app * acts as a [[:content:tech:Rhizome]] node, storing and forwarding files and [[:content:tech:MeshMS]] messages * Fully interoperable with first generation Mesh Extenders ==== First-Generation Mesh Extenders (deprecated) ==== The earlier phase of development was based around TP-Link MR3020 wireless routers, and is now fully deprecated. For people wanting to build a Mesh Extender compatible device, they should refer to the second-generation Mesh Extender documentation above, as it is possible to build a compatible device using a GL-INET AR150 wireless router, which is superior in all ways to the TP-LINK MR3020, not the least being that the GL-INET devices have an open boot-loader, a proper header for the onboard UART, four times the flash, and twice the RAM. {{:content:meshextender:meshextender-2014-02-11.jpg?180 |Pair of Serval Mesh Extenders on bench}} * powered by any external USB power source (5V 500mA) * Mesh Extenders mesh together over short distances using Ad Hoc Wi-Fi, and over longer distances using packet radio on the [[http://en.wikipedia.org/wiki/ISM_band|ISM 915 MHz band]]. Our ad-hoc packet radio system uses the RFD900 long-range UHF radio with custom CSMA firmware. * provides a standard Wi-Fi Access Point for nearby devices (such as smart phones) that do not support Ad Hoc Wi-Fi mode * offers the [[:content:tech:Serval Mesh]] app for Android for download via HTTP so that people can join the [[content:tech:mesh network]] without having previously installed the app * acts as a [[:content:tech:Rhizome]] node, storing and forwarding files and [[:content:tech:MeshMS]] messages * provides a platform for future Serval Project initiatives, such as the commoditisation of many classes of medical monitoring devices. ===== Satellite based services ===== ==== Outernet DreamCatcher ==== The following link explains our method to get a DreamCatcher working : [[Dreamcatcher|Dreamcatcher]] ===== Trial Deployments & Exercises ===== The following is a list of past and planned trial deployments and related activities. * Arkaroola Wilderness Sanctuary Demonstrator July 2010 * Nigeria InterNews Trial Jan 2011 * [[content:activity:KiwiEx 2012]] with NZ Red Cross Feb/March 2012 * [[content:activity:KiwiEx 2013]] with NZ Red Cross, New America OTI/Commotion and NLnet Foundation Feb/March 2013
