Re: WiFI on utility poles

I wish IEEE would natively support smaller channels as that's what's needed most of the time. Interference would be so 
much less. 

If there's opportunity for Comcast to work with the WISP community on channel selection to avoid mutual destruction, 
then great. 

That said, the cable company's efforts scream of OPM.

This is a huge deal for those people like myself that depend on fixed wireless for access at home because there is no 
broadband available despite incentives given by cities and states and the federal government. 

The local WISPs are good at coordinating access in these ISM bands amongst themselves but when someone appears with a 
SSID without doing a peek at the spectrum (note: not a site survey, but actual spectrum view w/ waterfall, as site 
survey only checks for the channel width that the client radio is configured for, not al the 10, 15, 8, 30mhz wide 
variants). 

It’s just poor practice to show up and break something else because you can’t be bothered to notice the interference or 
noise floor you created. I suspect the hardware that Comcast is using doesn’t notice this interference or adjacent 
channel issues. With the FCC aiming to let cell carriers also clog the 5ghz ISM band it’s only going to get worse.
