The other good thing is that they will (hopefully) keep using wifi where we can
use polling mechanisms easier today so we *should* be more protected against
the interference than we used to be with older 2.4 gig gear.

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....

Are you seeing any impact from them?

Yeah, won't matter either way with a 5Ghz AP on every street corner. 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).

What could go wrong with Comcast taking up yet more 5GHz of
spectrum...[/sarcasm off]

Comcast needs the FCC to open up the 5 GHz spectrum band to power
next-generation Wi-Fi services that could allow it to deliver wireless
broadband at speeds of up to 1 Gbps, SVP of Business Development Tom Nagel
testified at a House Energy and Commerce hearing on Wednesday.
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.
