Good hit.
This changes a lot my current perception (and prejudices) of RF signals.

A good place to start.

Thank you

Realistically GSM networks use 1W (IINM) which has a range of 2 Km's and BT which has a range of only few meters uses couple mw's (Headsets around 1 mw). Actually the further away from the tower GSM fries your brain better :).

Anyway, higher frequency needs lesser power to propagate longer distance.
