Re: What really grinds my gears.
First off, I did not propose a restriction. What I am proposing is an upgrade. While GMRS wasn't the best analog, it was a quick example that I could come up where licensed users are granted more transmitting power and more bandwidth where GMRS and FRS overlap (except for the 467MHz interstitial frequencies... those are identical) and granted access to repeater frequencies.
What I know is that the unregulated 2.4GHz non-ISM use is a hot mess in saturated environments because people simply believe that more power (transmitter output) and more APs is more better. They start buying these spider looking access points and place them in every corner of their home on odd-ball channels, thinking that more is always better.
That is no different than a large group of people in a room, subdivided into smaller groups of people conversing together and slowly each smaller group starts to speak louder to overcome the din of the entire room. Eventually all the smaller group are speaking louder and louder until everyone is screaming in order to be heard over the cacophony of the room.
That is my general impression of residential wifi today.
First topic, a firm understanding of wifi channels and what they actually represent.
Second topic, is related to channels are "wide" band settings.
Third topic is location, location, location. Poor AP positioning (physical) can do a lot to destroy throughput, even in low RF saturation areas.
Fourth topic is understanding mesh network design and understanding that wireless back haul is still shit in its current form and every form since 2007 when I tried to install my first wireless back haul. (To be clear, this is STRONGLY my personal opinion, but I think it is still an important topic nevertheless to understand everything going on behind the scenes.)
Fifth topic is understanding that it takes two to tango. Just because your signal strength is showing strongly on your device, that doesn't mean the same is true for that device talking back to the access point. Yea, there's RSSI/RCPI that's supposed to help.
So, there are some topics off the top of my head.
The obverse to those points is that is what is happening with some consumers of wifi today - an arms race thinking that more power and more antennas and wider bands are going to help them with higher speeds and/or lower latency or at least maybe the ability to out scream out their next door (or many doors down) neighbor(s).
How does one resolve that in an unlicensed space today?
1) Does one go and talk and try to educate other meatsacks about their RF pollution?
2) Does one foil their home over to prevent "noisy" meatsack's RF pollution who didn't take kindly to the earlier education attempt(s)?
3) Does one abandon wifi entirely?
4) Does one say fuckit and move to Green Bank, WV?
Personally, I've chosen option 3 as much as I can, except for where I can't - such as our iDevices and printer and laptops when they're not docked (which is most of the time).
Can an industry group get together and come up with an identical radio standard to Wifi, except instead of using the hot mess of an unlicensed space, carve out some licensed frequency where all participants of that space agree to the same set of rules by which all abide to with the ability to file grievances against other licensees and the ultimate penalty for failure of adherence when it causes undue interference - revocation of your license.
That space can even overlap with another licensed/restricted space with similar terms on how Wifi overlaps the 2.45GHz ISM band, except that you have to pass a test and pay a fee.
There you go, and I also didn't mention unwashed masses or plebs.
