"allows a device to use more than one channel at the same time"
I am really impressed with Wi-Fi technology in general. It deals with radio signals and the fact that we have the technology to use multiple channels at a given frequency is mind-boggling when you think about it.
I mean, you're sending out radio waves. They can overlap. How on Earth do we know how to determine what is part of what signal ?
Any technology that is sufficiently advanced can be regarded as magic. Well, Wi-Fi is kinda magic to me.
