There are some papers on wideband / high speed HF communication techniques. Most applications are basically backup for military applications when satellite communication fails.
I think it's an interesting topic, but with mesh networks and satellites, HF high speed links are not as relevant.
- CobaltFire 5y agoHF fills a different niche than mesh and satellite. Satellite has a reasonably high lower bound for implementation, and is reasonably easily disrupted. Mesh is reliant on a relatively high density of relays; typically you need nodes within a couple of miles of each other depending on terrain. HF allows for significantly larger mesh network node distances (with lower data rate) or much more robust communication that is harder to shut down.
