High-Speed Multimedia (HSMM) networks allow amateur radio operators to build robust, self-configuring data networks using commercial Wi-Fi gear on ham bands. These mesh networks provide high-bandwidth communication for various applications, from everyday data exchange to critical emergency communication. Hams leverage their frequency privileges to create resilient, local, and wide-area IP networks, often operating independently of commercial internet infrastructure. This capability is particularly valuable during public service events or disaster relief, where traditional communication channels might be compromised.

Operators interested in HSMM can find resources covering network fundamentals, hardware selection, and practical deployment strategies. Many sites offer guides on setting up mesh nodes and integrating applications, while others, like the European HAMNET, showcase large-scale regional networks. You can also find information on specific projects such as Broadband Hamnet, which focuses on adapting off-the-shelf routers for amateur radio use, and review experiments with HSMM on bands like 6 meters.
