HSMM-MESH (High Speed MultiMedia) is a great new technology that we as amateur radio Operators can take full advantage of. It's Wi-Fi on steroids!
We don't have to be hobbled by part 15 limitations, we can also use OUR frequency allocations, and avoid a majority of interference by part 15 devices.
Common, inexpensive off the shelf equipment is used and or simply modified for this application.
HSMM-MESH can enable Hams to have a robust mesh network for uses such as VOIP, callbook lookups, communication, SAR, mapping, EM-Comm, etc. The applications are endless!
