Industry Canada’s RSS-102 requirement are listed below and are slightly different from the FCC
regulation.
A calculation was perform to confirm the required safe distance for fixed service devices.
Limit for power density for general population/uncontrolled exposure was calculated for a power
density of max. 1 mW/cm
2 and for the frequency range 1500 -100000 MHz.
The power density P (mW/cm 2 ) = P
T
/ 4πr 2 , where
P
T
= the maximum equivalent isotropically radiated power (EIRP).
The minimum safe distance “r”, where RF exposure does not exceed the permissible limit, is:
r = sqrt { PT/ (Px4π)}
1. AireLink™ 60 SX system with 12 cm lens antenna
The maximum rms output power is 9.1 dBm and max antenna gain is 36 dBi. This corresponds to the
equivalent isotropically radiated power (EIRP) of 9.1 dBm + 36 dBi = 45.1 dBm, which is equal to
32359 mW.
r = sqrt { PT/ (Px4π)} = sqrt {32359 / 12.56} = 50 cm or 1.7 feet
