Shenzhen Branch Building 12&13, Zhiheng Wisdomland Business Park, Nantou Checkpoint Road 2, Nanshan District, 518052 Shenzhen, CHINA Page 53 of 53 Radiofrequency radiation exposure evaluation This exposure evaluation is intended forFCC ID: 2AX6LQTMDWR10 According to KDB 447498 D01v06 section 4.3.1, For frequencies between 100 MHz to 6GHz and test separation distances ≤ 50 mm, the Numeric threshold is determined as: Step a) [(max. power of channel, including tune-up tolerance, mW) / (min. test separation distance, mm)] · [√f(GHz)] ≤ 3.0 for 1-g SAR >> The fundamental frequency of the EUT is 2402-2480MHz, the test separation distance is ≤ 50mm. (5mm is the worst case according to the KDB) Step b) >> Numeric threshold (2402MHz), mW / 5mm * √2.402GHz ≤ 3.0 Numeric threshold (2402MHz) ≤ 9.678mW >> Numeric threshold (2440MHz), mW / 5mm * √2.440GHz ≤ 3.0 Numeric threshold (2440MHz) ≤ 9.602mW >> Numeric threshold (2480MHz), mW / 5mm * √2.480GHz ≤ 3.0 Numeric threshold (2480MHz) ≤ 9.525mW >> The power (measured + tune up tolerance) of EUT at 2402MHz is: -0.10dBm = 0.98mW The power (measured + tune up tolerance) of EUT at 2440MHz is: 0.00dBm = 1.00mW The power (measured + tune up tolerance) of EUT at 2480MHz is: 0.05dBm = 1.01mW Which is smaller than the Numeric threshold. Therefore, the device is exempt from stand-alone SAR test requirements.
