That is actually my only hurdle, the funding to develop the radios, and because it is fundamentally different from the thinking of how to do radios....
I'll give you an example. All Wi-Fi radios are using technology that's 25 years old, developed in Germany. I can't even remember what it's called. It was hacked years and years ago, but if you write a proprietary code for a Wi-Fi radio, people lose their minds. The security is there, however, so I will run with my proprietary code, and I'll just deal with the people losing their minds.
