FCC ID: 2AOMX-BT579 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. For BLE mode Frequency (MHz) Output power to antenna (dBm) Ant gain(dBi) EIRP(dBm) ERP(dBm) ERP(mw) Distance (cm) P th (mW) 2480 1.83 -0.58 1.25 -0.9 0.81 0.5 2.7 ERP = EIRP −2.15 dB WORSE CASE 0.81mW<2.7mW Remark: Then SAR evaluation is not required
