What do you think about the idea ?
I understand the strength of the XBee's signal is coded only on a 5-steps scale,
why would a bunch of receivers be needed ?
Couldn't one apply triangulation with only four receivers ?
Then, could Bluetooth or Wi-Fi have a finer scale to evaluate a signal's strength ?
It seems I am not the only one to think about triangulation with XBees or similar radio devices
