Ok. So .. simple question that going back to basics doesn't make a whole lot of sense. I'm going to skip a lot of variables -- transmit power, dBi, SNR, interference, etc - and keep it as simple as possible.
What is the relationship between wireless coverage (square footage) vs range?
For instance, a Google WiFi AP is rated at 1500 square foot coverage. We'll use 1600 for simple math. Since most APs use omni-directional antennas, that means the AP is in the center of the coverage. That should roughly be a 40x40 box, or a circle with a 20' radius (more accurately 22.5').
So, how is it that the actual range from a client to the AP - and still have a usable signal - can be 50 foot, or more? How can wireless N be rated at maximum range of 230 ft?
I know there are a LOT of variables with wireless. There is just an obvious disconnect somewhere in my brain.
