  1. An amateur-radio data network using commercial Wi-Fi equipment with modified firmwareПравильный ответ
  2. A wide-bandwidth digital voice mode employing DMR protocols
  3. An amateur-radio satellite communications network using modified commercial satellite TV hardware
  4. An internet linking protocol allowing communication through repeaters around the world

Объяснение

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.
