Which of the following frequencies can be used for amateur radio mesh networks?

Amateur radio mesh networks, often built using technologies like AREDN (Amateur Radio Emergency Data Network), utilize repurposed commercial Wi-Fi equipment. Because commercial Wi-Fi operates on the 2.4 GHz, 3.4 GHz, and 5.8 GHz bands, hams use these exact same microwave frequencies. These specific frequency bands are shared with various unlicensed wireless data services, such as typical Part 15 consumer Wi-Fi routers. Amateur radio operators have allocated segments within or adjacent to these bands where they can legally use higher transmit power and specialized directional antennas under Part 97 rules. HF frequencies or the 60-meter band do not provide anywhere near the necessary bandwidth for high-speed, broadband mesh networking, making those distractors incorrect.
