The answer is, if someone is using your hotspot, it does use the same radio and channel your ssid is on. On Wed, Dec 10, 2014 at 11:18 PM, Andrew Jones <aj () jonesy com au> wrote:
It reads to me like it's not a separate Wi-Fi radio on a different channel, but just an additional SSID being broadcast: http://wifi.comcast.com/faqs.html ctrl+f "Does the new Home Hotspot impact my Internet speeds or data usage?"

I don't know if they are allocating specific channels for it or if it's just a different service flow, but either way it is a lower priority and should not cause contention with regular user traffic. Really it is just the power they seem to be complaining about.

I haven't been keeping up with the technology, but in the ancient of days wasn't the uplink side of DOCSIS also a limited-bandwidth, shared resource?
