Which of the following best describes an amateur radio mesh network?
An amateur-radio data network using commercial Wi-Fi equipment with modified firmware✓Bonne réponse
A wide-bandwidth digital voice mode employing DMR protocols
An amateur-radio satellite communications network using modified commercial satellite TV hardware
An internet linking protocol allowing communication through repeaters around the world
Explication
Amateur mesh networking, as in AREDN and Broadband-Hamnet, takes inexpensive commercial Wi-Fi routers and replaces their firmware so they operate as a self-organizing amateur data network on channels that overlap the amateur bands. It is a data network, not a voice mode, a satellite system or a repeater linking protocol.
