Is their a way to accurately (3inch max tolerance) measure distance between multiple devices in a single story building. Using only RF signals? Imagine a square building with any random amount of wall/rooms etc. I have a master device located in known area of the building and any number of "slave devices" in unknown areas of the buiding, but slave devices are capable of "talking" to the master device or any slave device per request of the master. Now take the building and divide it into four even parts so that their is section 1, section 2, section 3, and section 4. The master device is located in section 1 , so I guess this is my question: Is their a way that I can calculate the distance of the slave devices from the master device to the degree that I could know what section the slave devices are in. Is it possible with RF signals, through walls and obstacles and such?
