What is the primary purpose of an Amateur Radio Emergency Data Network (AREDN) mesh network?

  1. ATo provide FM repeater coverage in remote areas
  2. BTo provide real time propagation data by monitoring amateur radio transmissions worldwide
  3. CTo provide high-speed data services during an emergency or community event
  4. DTo provide DX spotting reports to aid contesters and DXers
Why AREDN (Amateur Radio Emergency Data Network) firmware turns inexpensive commercial Wi-Fi routers into amateur band nodes on frequencies like 2.4 GHz, 3.4 GHz and 5.8 GHz that automatically link to each other in a self-healing mesh. The point is a local high-speed IP network that can carry VoIP, video, file transfer, email and served-agency applications when the internet or other infrastructure is down, or to support a public service event. It is a data infrastructure, not a voice repeater system or a reporting service.
Watch out The propagation-monitoring choice describes systems like WSPR, PSK Reporter or the Reverse Beacon Network, and the spotting choice describes DX cluster networks, both of which are internet-based reporting tools rather than an emergency data network.
Read the name: Amateur Radio EMERGENCY DATA Network. Emergency plus data equals high-speed data in emergencies.
