Question
What is the primary purpose of an Amateur Radio Emergency Data Network (AREDN) mesh network?
Answer Options
- A) To provide FM repeater coverage in remote areas
- B) To provide real time propagation data by monitoring amateur radio transmissions worldwide
- C) To provide high-speed data services during an emergency or community event
- D) To provide DX spotting reports to aid contesters and DXers
Correct Answer: C
Explanation
The Amateur Radio Emergency Data Network (AREDN) uses licensed amateur frequencies, typically in the 2.4 \text{GHz} and 5.8 \text{GHz} bands, to create a self-forming, redundant, high-speed data mesh network. The primary purpose of this network is to provide high-speed data services during an emergency or community event.
AREDN provides capabilities such as Voice over IP (VoIP), streaming video, and high-speed network connections for hospitals, emergency operations centers, and shelters when commercial Internet or cellular services are unavailable. Its mesh topology ensures that if one node fails, data can be automatically routed through an alternate path, increasing its reliability during a disaster.
