Are you an Amateur Radio operator? If not, it's easy to get your license now. Broadband-Hamnet is just one of the many interesting things you can do with a ham license.
Frankly, I find Broadband-Hamnet to be one of the most interesting Amateur Radio projects in many years. The ability to build a very usable network by simply bringing two or more mesh nodes within communications range of each other, without having to do any further configuration, is pretty awesome.
One of the ham groups in our county is working with the county Emergency Management team to create a back-up network, using Broadband-Hamnet, between the Emergency Operations Center and the local hospital, which is about four miles away. The hospital is also working to create a back-up network with other hospitals in the region, also using Broadband-Hamnet.
These are interesting times in which we live!
