Thanks for the link. Nice graphics. That is pretty much what I tell non-technical groups such as a Computer Club. I was hoping for some technical details.
My guess goes something like this. Router #1 receives packets of data from the Internet sequentially but never sees packets intended for Router #2. Sharing channel 6 for example does not slow this down. Thus the problem is with the device. The device detects everything on channel 6 and receives packets from Router #1 sequentially. Not sure how packets sent from Router #2 on channel 6 fit this scheme. Somehow (?) the device handles that perceived problem. Does the delay occur because the device has to look at the packet headers, determine the packet is not theirs and move on? That would seem to take a small fraction of time compared to processing and decoding a packet for the device. Hence, no appreciable delay.
In short, my analogy and the analogy in your link does not fit my picture of what happens. The device takes a certain amount of time to receive and process a data packet from its Router (without another Router on channel 6 this time is short enough to keep up with the packets received). With another Router on channel sending packets, the device recognizes this packet does not have to decoded in a time very short compared to the time for its own packets. Thus, little or no slow down. I realize something is wrong with that picture since I have seen what I call "Congestion" (as opposed to true "Interference") but I would like to close the gap in my so-called 'understanding'. Thanks
