The standard FCC response to your request would be the MOSH session would run great on existing 802.11 regulated under 47CFR15.247 (probably?) so trying to implement it under 47CRF97 is a paperwork mistake. A step up from consumer wifi gear, the specific term to google for would be U-NII as in the thingie that WISP wireless ISPs operate under. My understanding of U-NII gear (which might be wrong) is by definition its unlicensed. Its long distance performance crushes anything wifi can do (legally, anyway LOL). My understanding of U-NII is 47CFR15.407 which is a different subsection than consumer wifi. If you feel really ambitious, FCC Part 101 service is the way to go if you want real distance. A license is a couple hundred bucks new or renewed. Your electric bill for the equipment for part 101 service will cost more than that, I think. Just because a Part 73 renewal costs about a new car per year, doesn't mean ALL the fees are draconian. You can certainly spend more on unlicensed 802.11 gear than on used Part 101 gear as a complete system; its not even remotely unrealistic for a private citizen to do part 101 stuff for fun. If you're feeling really really really ambitious the cost of a form 442 experimental request was ridiculous like sixty bucks. But thats for really exotic experimentation like we're inventing new hardware and new protocols. And a 442 request is by definition not an existing service so they may well respond with an allocation and temporary license that doesn't work for you. The point of all this is the FCC already has four services you can operate under, ranging from literally free up to a serious but realistic hobby expense, so changing the rules of an existing fifth service is going to be a very hard sell. Like, seriously, none of the four services they offer fit your needs, not even the $60 experimental request form? Extensive historical part 97 operation indicates encryption has never been useful or required for the other goals mentioned such as casual conversation or operating portable communications systems, so the FCC is not going to take that subgoal very seriously at all.
