Maybe it's not the case with the Apple product, but I think that one tag that BA tried out (and I think even launched, Alex was fully behind that) had the ability of 'bouncing' its signal off other Bluetooth/radio beacons. It still had the same issues as I described in the post above, though, and its usefulness can be synthetised as being rather limited.
Ditto GPS.
