Power density (S) is calculated according to the formula:

S = PG / (4πR²)

Where S = power density in mW/cm²
P = transmit power in mW
G = numeric gain of transmit antenna (numeric gain=Log-1(dB antenna gain/10))
R = distance (cm)

The calculations in the table below use the highest gain of antenna for client EUT. These
calculations represent worst case in terms of the exposure levels.
Frequency band Power Antenna Gain R S Limits

(MHz) dBm mW dBi (Numeric) (cm) (mW/cm2) (mW/cm2)

2402 - 2480(BLE) 8.233 6.66 2 1.585 20 0.002 1

For DWAM83 module:

Frequency band Power Antenna Gain R S Limits

(MHz) dBm mW dBi (Numeric) (cm) (mW/cm2) (mW/cm2)
2412 ~ 2464 19.49 88.92 2 1.585 20 0.028 1
5180 ~ 5240 7.44 5.55 2 1.585 20 0.002 1
5736 ~ 5814 16.84 48.31 2 1.585 20 0.015 1
Note: 1 mW/cm2 from 1.310 Table 1

For the device consider simultaneous transmission of BLE and DWAM83 module 5GHz,

The worst MPE = 0.002 + 0.015 = 0.017 mW/cm2 < 1 mW/cm2.

Appendix I

Definition below must be outlined in the User Manual:

To satisfy FCC RF exposure requirements, a separation distance of 20 cm or more should be
maintained between the antenna of this device and persons during device operation.
To ensure compliance, operations at closer than this distance is not recommended.
