affected by absorption and reflection from structures, objects and people.
Electromagnetic environment – guidance
Portable and mobile RF communications equipment should be used no closer
to any part of the device, including cables, than the recommended separation
distance calculated from the equation applicable to the frequency of the transmitter.
Recommended separation distance
d = 1.17 √P
d = 1.17 √P 80 MHz to 800 Mhz
d = 2.33 √P 800 MHz to 2,5 GHz
