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)

As we can see from the test report 171001524SHA-001, 171001524SHA-002, 171001524SHA-003 and
171001524SHA-004:

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.

The 2.4G Band WiFi and 5G Band WiFi cannot can support simultaneous transmission, the Bluetooth and
WiFi can support simultaneous transmission.

5725-5850 16.24 3.30 20 0.0179 1
Note: 1 mW/cm2 from 1.310 Table 1

For the device can support simultaneous transmission, according to 447498 D01 General RF
Exposure Guidance v06,
For the device consider simultaneous transmission of WiFi and Bluetooth:
The worst MPE = 0.0011 + 0.0179 = 0.0190 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.
