If we could get cognitive radio going over SDRs, mesh networks using automatic frequency hops to the nearest radio whitespace would become drop-dead easy.
From there, the FCC could issue regulations to the tune of 'use any non-military band for up to X seconds, provided you confirm you are not interfering with any other traffic every Y milliseconds' and the entire licensing scheme of "radio bandwidth is a finite good" could be virtually eliminated. It would be like going from IPv4 to IPv6 in terms of total amounts of available IP addresses.
- superkuh 7y agoThe lack of technologies like cognitive radio aren't preventing mesh networks. If you're talking the useful bands for data transmission (ie, VHF and up but mostly very up) then the only thing that matters is height above terrain. Unfortunately except for exceptional situations (coastal mountains or megacity roofs) that height and getting power up there costs a lot of money. That's why neighborhood and city mesh networks don't work. And it's why cell networks do.
