High Speed Multimedia – The Amateur Radio bands above 50 MHz can support computer-to-computer communications at speeds high enough to support multimedia applications. Multimedia in this case refers to voice, data and image communications. Hams call this HSMM—high speed multimedia.

What is the Amateur Radio Emergency Data Network (AREDN)?
AREDN is a custom firmware designed to run on commodity hardware that provides a way for amateur radio operators to create high-speed, ad-hoc, data networks to support emergency and community-service communications.
How can Washington County ARES/RACES utilize AREDN?
AREDN creates an IP network, just like our own private internet, allowing us to do things like send larger amounts of data via Winlink, send webcam video, exchange data files, and much more.
What is the quickest way to get active with AREDN at home or at a served agency?
As of today, 02/07/2024, I recommend purchasing a Mikrotik hAP ac2 (about $80 on Amazon.com) and flashing the AREDN firmware on it (latest AREDN documentation here). You can also reach out to me directly to get one pre-configured and ready to go.
How do I get connected to the AREDN mesh? I don’t have an AREDN node near me to connect via RF.
The AREDN development team has integrated a function into their firmware allowing for the creation of a regional Supernode via the internet. This helps to resolve an old problem with mesh networks where they would get interlinked and grow too large, causing slowdowns and frequent disconnections.
I’m operating a regional Supernode here in Hillsboro with a dedicated tunnel server on an enterprise class fiber connection with backup power. I invite our local ARES members and served agency stations to join the mesh via our existing internet connections so we can start utilizing mesh services and encourage the expansion of the RF mesh network as well. Contact me to get access to the regional tunnel server so you get into the Supernode.
