[WiFi] Xfinity WiFi | Carrier WiFi NANOG Presentation

Comcast had a really good presentation at NANOG last week in Baltimore on their experiences operating a carrier grade wifi network. Figured there is some interest here.

Interesting stuff!

(For the sake of this presentation, I'm ignoring the whole "should Comcast be piggybacking on customer access points?" topic.)

Yeah. My takeaways were:
1) We need more spectrum dedicated to wifi.
2) 802.11r doesn't scale (also poor adoption in clients).
3) There needs to be an open controller protocol for interfacing with access points and the controller software.

Re: [WiFi] Xfinity WiFi | Carrier WiFi NANOG Presentation

When it comes to hotspots/wireless receiver APs on 5 GHz, I feel like they should be all on 1 channel, away from actual consumer networks. They should all dedicate themselves to using channel 165 since I don't see much consumer gear actually letting that channel be used unless it wants to be forced to 20 MHz.
