3 SUMMARY OF TEST RESULT

3.1 Test Standards

4 DEVICE CATEGORY AND LEVELS LIMITS

Portable Derives:

CFR Title 47 §2.1093(b)

(b) For purposes of this section, a portable device is defined as a transmitting device designed to be used so that the radiating structure(s) of the device is/are within 20 centimeters of the body of the user.

FCC KDB 447498 Derives:

According with FCC KDB 447498 D04, Appendix B, The SAR-based exemption formula applies for single fixed, mobile, and portable RF sources with available maximum time-averaged power or effective radiated power (ERP), whichever is greater, of less than or equal to the threshold Pth (mW).

This method shall only be used at separation distances from 0.5 cm to 40 cm and at frequencies from 0.3 GHz to 6 GHz (inclusive). The following table shows the power threshold from 5mm to 50mm.

Note:

1. Maximum power is the source-based time-average power and represents the maximum RF output power including tune-up tolerance among production units.
2. Per KDB 447498 D04, for larger devices, the test separation distance of adjacent edge configuration is determined by the closest separation between the antenna and the user.
3. Per KDB 447498 D04, standalone SAR test exclusion threshold is applied; If the distance of the antenna to the user is < 5mm, 5mm is used to determine SAR exclusion threshold.
4. Per KDB 447498 D04, for separation distances from 0.5 cm to 40 cm and at frequencies from 0.3 GHz to 6 GHz (inclusive), the threshold Pth (mW) is given by Following:

Pth (mW) = 60 / ( (f(GHz)^0.8) * (d/20cm) ) for d ≤ 20cm

Pth (mW) = 60 / ( (f(GHz)^0.8) * (20cm/d) ) for 20cm < d ≤ 40cm

where

x = -log10( (ERP20cm / (1000mW/W)) / (60) )

a. f(GHz) is the RF channel transmit frequency in GHz

b. d is the separation distance (cm), The result is rounded to one decimal place for comparison

c. ERP20cm are determined by:

ERP20cm(mW) = f(x) = { 20*f(GHz) if 0.3GHz < f < 1.5GHz ; 30*f(GHz) if 1.5GHz ≤ f ≤ 6GHz }

5 ASSESSMENT RESULT

5.1 Output Power

Note: This report listed the worst case power value, please refer to BL-SZ23A1021-601 report for more details.

Note: This report listed the worst case power value, please refer to BL-SZ23A1021-602 report for more details.

5.2 Tune-up power

Note1: ERP= EIRP -2.15dB

Note2: According KDB 447498 D04, used the greater of maximum conducted power and ERP to compare with the threshold value Pth.

5.3 RF Exposure Evaluation Result

5.4 Conclusion

This EUT is deemed to comply with the reference level limits, therefore the basic restrictions are compliant with human exposure limits.
