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. Single RF Sources Subject to Routine Environmental Evaluation RF Source frequency (MHz) Threshold ERP (watts) 0.3-1.34 1,920 R 2 1.34-30 3,450 R 2 /f 2 30-300 3.83 R 2 300-1,500 0.0128 R 2 f 1,500-100,000 19.2R 2 For Multiple RF sources: FCC Rule Part 1.1307(b)(3)(ii): (A) The available maximum time-averaged power of each source is no more than 1 mW and there is a separation distance of two centimeters between any portion of a radiating structure operating and the nearest portion of any other radiating structure in the same device, except if the sum of multiple sources is less than 1 mW during the time-averaging period, in which case they may be treated as a single source (separation is not required). (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 2402 1.31 -0.58 100 2.00 -0.73 Frequency Option Min.
