2. Applicable Standard
According to §1.1307 the criteria listed in table 1 shall be used to evaluate the environmental impact of human exposure to radio frequency (RF) radiation as specified in §1.1307(b), except in the case of portable devices which shall be evaluated according to the provisions of §2.1093 of this chapter. Test Limits
Evaluated against exposure limits: General Use _X_ or Controlled Use ___
Maximum Permissible Exposure (MPE)

f = frequency in MHz* = Plane-wave equivalent power density RF exposure compliance will need to be determined with respect to 1.1307(c) and (d) of the FCC rules. The emissions should be within the limits at 300kHz in the above table. (Use 300kHz limits for 150kHz)

3. Test Results
Equation from page 18 of OET Bulletin 65, Edition 97-01
S = PG/4R²
Where,
S = power density (mW/cm2) P = output power at the antenna terminal (mW) G = gain of transmit antenna (numeric) R = distance from transmitting antenna (cm)
For Bluetooth Transmitter
Maximum peak output power at antenna input terminal = 9.03 (dBm) Maximum peak output power at antenna input terminal = 7.99 (mW) Antenna gain (typical) = 2.0 (dBi) Maximum antenna gain = 1.58 (numeric) Prediction distance = 20 (cm) Prediction frequency = 2480 (MHz) MPE limit for uncontrolled exposure at prediction frequency = 1.0 (mW/cm^2) Power density at prediction frequency = 0.00251 (mW/cm^2)
To solve for the minimum mounting distance required;
R =  (PG/4S)
R =  (7.99 x 1.58 / 4 x 0.00251) = 20 cm (Based on continuous transmission)

For Wifi Transmitter
Maximum peak output power at antenna input terminal = 24.35 (dBm) Maximum peak output power at antenna input terminal = 272.27 (mW) Antenna gain (typical) = 2.0 (dBi) Maximum antenna gain = 1.58 (numeric) Prediction distance = 20 (cm) Prediction frequency = 2462 (MHz) MPE limit for uncontrolled exposure at prediction frequency = 1 (mW/cm^2) Power density at prediction frequency = 0.08558 (mW/cm^2)
To solve for the minimum mounting distance required;
R =  (PG/4S)
R =  (272.27 x 1.58 / 4 x 0.08558) = 20 cm (Based on continuous transmission)

Simultaneous Transmission Evaluation
Limit The sum of the ratios of the peak or spatially averaged results to the applicable frequency dependent MPE limits must be <1 at all locations where users and bystanders can by exposed.

Calculation
Mode Bluetooth Power Density/Limit
WiFi Bluetooth 0.00251

WiFi Power Density/Limit
0.08558

(Power Density/Limit) of WiFi+Bluetooth
0.088

The WiFi and Bluetooth transmitter, the aggregated (power density/limit) is smaller than 1, and the MPE of 2 collocated transmitters is compliant.
