Option A: FCC Rule Part 1.1307 (b)(3)(i)(A):The available maximum time-averaged power is no more than 1mW, regardless of separation distance. Option B: FCC Rule Part 1.1307 (b)(3)(i)(B): The available maximum time-averaged power or effective radiated power (ERP), whichever is greater, is less than or equal to the threshold P th (mW) described in the following formula. P th is given by: Option C: FCC Rule Part 1.1307 (b)(3)(i)(C): The minimum separation distance (R in meters) from the body of a nearby person for the frequency (f in MHz) at which the source operates, the ERP (watts) is no more than the calculated value prescribed for that frequency. R must be at least λ/2π, where λ is the free-space operating wavelength in meters.

(B) In the case of fixed RF sources operating in the same time-averaging period, or of multiple mobile or portable RF sources within a device operating in the same time averaging period, if the sum of the fractional contributions to the applicable thresholds is less than or equal to 1 as indicated in the following equation. 1.3 Calculated Result Radio Access Technology Prediction Frequency Output Power Antenna Gain Duty Cycle Tune-Up Time-Averaged Power ERP (MHz) (dBm) (dBi) (%) (dBm) (dBm) Bluetooth-BR/EDR 2402 1.75 1.86 100 2.00 1.71 Bluetooth- LE 2402 -1.71 -0.58 100 -1.00 -3.73 Frequency Option Min.
