RF Exposure evaluation

FCC ID: 2AI5N-RJPRO61

According to 447498 D04 Interim General RF Exposure Guidance v01

ERP/EIRP = PT+GT -LC ERP/EIRP is the equivalent (or effective) radiated power [in same units as PT, typically dBW, dBm, or power spectral density (psd)], relative to either a dipole antenna (ERP) or an

isotropic antenna (EIRP).

PT is the transmitter output power, in dBW, dBm, or psd (power over a specified reference bandwidth).

GT is the gain of the transmitting antenna, in dBd (ERP) or dBi (EIRP). LC is the signal attenuation in the connecting cable between the transmitter and the antenna, in dB.
