FCC ID: 2BUZR-BLUEV138 RF Exposure evaluation According to 447498 D04 Interim General RF Exposure Guidance v01 ERP/EIRP = P T +G T −L C ERP/EIRP is the equivalent (or effective) radiated power [in same units as P T , typically dBW, dBm, or power spectral density (psd)], relative to either a dipole antenna (ERP) or an isotropic antenna (EIRP). P T is the transmitter output power, in dBW, dBm, or psd (power over a specified reference bandwidth). G T is the gain of the transmitting antenna, in dBd (ERP) or dBi (EIRP). L C is the signal attenuation in the connecting cable between the transmitter and the antenna, in dB.
