| | |
| | ==== 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. |

| | ==== Outernet DreamCatcher ==== |
| |
| 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. The objectives are: | The following link explains our method to get a DreamCatcher working : [[Dreamcatcher|Dreamcatcher]] |
| * allow devices that do not support Ad Hoc WiFi mode to join the [[content:tech:mesh network]]; | |
| * minimise power consumption for devices; | |
| * support alternative radio interfaces to offer better range and/or throughput than WiFi; | |
| * provide a platform for future Serval Project initiatives, such as the commoditisation of many classes of medical monitoring devices. | |
