The nodes are small and entirely self-contained units that can be deployed simply by leaving them in a place with sun. They are intended for either manual or drone-deployment on rooftops or in windows. They use a high gain omni-directional antennas on 915 MHz using the LoRa PHY (Chirp Spread Spectrum) to talk to each-other and a downward-pointing/inward-pointing high gain wifi antenna to talk to user devices (phones/tables/laptops) inside the building on which they are placed. They use a low-power microcontroller running a web server that lets anyone use the network as long as they have a device with wifi and a web-browser. | |||
Bandwidth is < 2000 kbits/sec. | |||
The in-development apps are secure chat and resource mapping (an offline map that the community can use to add resources, like [http://tidepools.co/ tidepools]). | |||
