Hello, friends!
I've google about the question below but no success!
The question is:
Gps signals inside buildings are nonexistent or very weak, but mobile phone and am and fm radio signals are good, so the question is: why gps satellites and mobile phone comunications don't use emission on the radiowave band, which is less dangerous for our health.
TIA
