TABLE 2 OCR 800 MPE Safe Distances in cm for Various Antenna Gains
If the antenna gain is not listed in Table 1 and Table 2, the MPE Safe Distance is calculated as
follows:
Calculation Method for RF Safety Distance r:
S = PG/4Πr
2
=EIRP/4Πr
2
Where: P: power input to the antenna in mW.
EIRP: Equivalent (effective) isotropic radiated power in mW.
S: power density mW/cm
