I'm not talking about the ones in peoples homes, I'm talking about the ones the cable carrier hangs on the lines outside runing through the city on every corner.... clear LOS to every tower around.

One good thing about the higher bands and the noise floor is that free space loss works to your advantage. That being that a 5 GHz indoor Omni home AP router signal will fall off as an interference source as a much shorter distance than a 2.4 GHz device will. The laws of physics work in your favor.

Hard to tell, noise floor is noise floor which keeps creeping up - we all know things work better when its quiet. This used to worry me a lot when I saw it coming, but then I realized it was already there and I had no idea until I just happened to scan on some radios (I don't usually install the stuff). I'm not worried any more, if its not one thing it will be another any way. Thats what gives us the edge every day, flexibility. We will work around it, we always do. I figure a high gain antenna on a tower with a good directional CPE will continue to work fine. Their omni low gain antenna can't compete with a 20-30db directional one. Still sucks though, you drive down the street and see one after another running 5Ghz just knowing there probably isn't 3 connections in the whole city to them....

Already seeing that in our areas.... do a wireless scan and you see 354 5Ghz APs now in addition to the 2Ghz ones (they run dual band APs now).

Nagel disclosed in his prepared testimony that Comcast has expanded the number of Wi-Fi access points for Xfinity high-speed Internet customers to 350,000. The nation's largest cable MSO also began deploying wireless gateways from Cisco earlier this year that Comcast has said may be able to power millions of neighborhood hotspots. While Comcast already is already using the 5 GHz band, Nagel said it needs more of the unlicensed spectrum to meet demand from subscribers for Wi-Fi. It faces potential opposition from Toyota and other automobile manufacturers who want to use the 5 GHz band to deliver next-generation connected car applications, including applications that would warn drivers of collision threats. Toyota principal researcher John Kenney raised concerns about possible interference from Wi-Fi services at Wednesday's hearing. "We have been actively engaged with the Wi-Fi community and other stakeholders who are exploring possible sharing solutions that will alleviate any risk of harmful interference from unlicensed devices. But we're not there yet and it's going to take a bit more time to see if we can get there," Kenney said in his prepared testimony.
