Which of the following best describes an amateur radio mesh network?
The correct answer is A: An amateur-radio based data network using commercial Wi-Fi equipment with modified firmware. An amateur radio mesh network is an amateur-radio based data network using commercial Wi-Fi equipment with modified firmware. Mesh networks create interconnected nodes that can relay data, forming a self-organizing network. Amateur mesh networks typically use 802.11 (Wi-Fi) hardware with special firmware that allows them to operate on amateur bands and form mesh topologies. For amateur radio operators, mesh networks provide high-speed data communications and can extend coverage through multiple hops. Understanding mesh networks helps explain modern high-speed amateur data networks.
Exam Tip
Amateur mesh network = Wi-Fi equipment with modified firmware. Think 'M'esh = 'M'odified 'W'i-'F'i equipment. Commercial Wi-Fi hardware with special firmware for amateur mesh networking. Not DMR voice, not satellite TV hardware, not internet linking.
Memory Aid
"Amateur mesh network = Wi-Fi equipment with modified firmware. Think 'M'esh = 'M'odified 'W'i-'F'i. Commercial Wi-Fi hardware with special firmware for amateur mesh data networking. Self-organizing network topology."
Real-World Application
Your local amateur radio club sets up a mesh network using commercial Wi-Fi routers with modified firmware. These nodes automatically form a mesh - if one node can't reach another directly, data hops through intermediate nodes. This creates a high-speed data network covering your area, allowing file sharing, messaging, and internet gateway access. The mesh network uses 802.11 equipment on amateur bands.
Key Concepts
Why Other Options Are Wrong
Option B: Incorrect. Mesh networks aren't wide-bandwidth digital voice using DMR - DMR is a different digital radio standard. Mesh networks are data networks, not voice systems.
Option C: Incorrect. Mesh networks aren't satellite communications using modified TV hardware - that's a different application. Mesh networks use Wi-Fi equipment.
Option D: Incorrect. Mesh networks aren't internet linking protocols for repeaters - that's IRLP or EchoLink. Mesh networks are local data networks.
