 = Introduction =
-DisasterRadio uses cheap software defined radios (SDRs) to create a low bandwidth disaster-recovery mesh. Disasters being either natural (e.g. earthquake) or man-made (e.g. extreme censorship scenarios).
+DisasterRadio is an off grid (solar powered) low bandwidth long range mesh network.
-The goal of DisasterRadio is to allow people to communicate short text messages that optionally include GPS coordinates in the event of a disaster, both within the affected area and to the outside world. A map-based interface allows people to find resources such as medical facilities, cell phone charge stations, food, shelter, etc.
+Nodes currently use the LoRa PHY (CSS modulation) to communicate between each-other, and WiFi to communicate with client devices.
-The mesh will have many receive-only nodes and fewer transmit-capable nodes, due to the much higher cost of transmit-capable SDRs.
+Web apps like chat / microblogging are served up over the wifi connection, requiring only a client device with wifi and a web browser to use.
