Standard Applicable
According to § 1.1307(b)(1) and KDB 447498 D01 General RF Exposure Guidance v06, system operating under the provisions of this section shall be operating in a manner that the public is not exposed to radio frequency energy level in excess limit for maximum permissible exposure.
Limits for Occupational / Controlled Exposure
| Frequency range (MHz) | Electric Field Strength (E) (V/m) | Magnetic Field Strength (H) (A/m) | Power Density (S) (mW/cm²) | Averaging Times | E |², | H |² or S (minutes) |
|---|---|---|---|---|
| 0.3-3.0 | 614 | 1.63 | (100)* | 6 |
| 3.0-30 | 1842/f | 4.89/f | (900/f)* | 6 |
| 30-300 | 61.4 | 0.163 | 1.0 | 6 |
| 300-1500 | / | / | F/300 | 6 |
| 1500-100000 | / | / | 5 | 6 |
Limits for General Population / Uncontrolled Exposure
| Frequency range (MHz) | Electric Field Strength (E) (V/m) | Magnetic Field Strength (H) (A/m) | Power Density (S) (mW/cm²) | Averaging Times | E |², | H |² or S (minutes) |
|---|---|---|---|---|
| 0.3-1.34 | 614 | 1.63 | (100)* | 30 |
| 1.34-30 | 824/f | 2.19/f | (180/f)* | 30 |
| 30-300 | 27.5 | 0.073 | 0.2 | 30 |
| 300-1500 | / | / | F/1500 | 30 |
| 1500-100000 | / | / | 1 | 30 |
Note: f = frequency in MHz: * = Plane-wave equivalents power density
MPE Calculation Method
- S = (30*P*G) / (377*R²)
- S = power density (in appropriate units, e.g., mW/cm²)
- P = power input to the antenna (in appropriate units, e.g., mW)
- G = power gain of the antenna in the direction of interest relative to an isotropic radiator, the power gain factor is normally numeric gain.
- R = distance to the center of radiation of the antenna (in appropriate units, e.g., cm)
MPE Calculation Result
For Wi-Fi
- Maximum Tune-Up output power:
- 16.0 (dBm)
- Maximum peak output power at antenna input terminal:
- 39.81 (mW)
- Prediction distance:
- >20(cm)
- Prediction frequency:
- 2462 (MHz)
- Antenna gain:
- 1.0 (dBi)
- Directional gain (numeric gain):
- 1.26
- The worst case is power density at prediction frequency at 20cm:
- 0.0100 (mW/cm²)
- MPE limit for general population exposure at prediction frequency:
- 1 (mW/cm²)
For Bluetooth
- Maximum Tune-Up output power:
- 2.5 (dBm)
- Maximum peak output power at antenna input terminal:
- 1.78 (mW)
- Prediction distance:
- >20(cm)
- Prediction frequency:
- 2480 (MHz)
- Antenna gain:
- 1.0 (dBi)
- Directional gain (numeric gain):
- 1.26
- The worst case is power density at prediction frequency at 20cm:
- 0.0004 (mW/cm²)
- MPE limit for general population exposure at prediction frequency:
- 1 (mW/cm²)
Mode for Simultaneous Multi-band Transmission
- Bluetooth + Wi-Fi
- The worst case is power density at prediction frequency at 20cm: 0.0100/1+0.0004/1 = 0.0104<1
Result: Pass
