In practice this sucks more than one would imagine. In a cluttered environment all you get reliably is close, near, far, somewhere else. Because you have 10-30db multipath fades and attenuation exponents are on the order of 2.5 to 3.5

You can spoof that too, with a relay. In fact, just putting the relay transmit antenna in the expected place should give the right ratio of RSSI.

Seems silly to imagine, but it is possible and I didn’t consider that.
