                                                       RF exposure Estimation
1.         Introduction
           5996611U5 (FCC ID: 2AGBW19USDL456XY) is a LED RETROFIT LUMINAIRE, which
           contains Zigbee and BLE function inside.

2.         Limit and Guidelines on Exposure to Electromagnetic Fields
           According to §1.1307(b)(1), systems operating under the provisions of this section shall be
           operated in a manner that ensure that the public is not exposed to radio frequency energy level
           in excess of the Commission’s guideline.

           According to KDB 447498 D01 General RF Exposure Guidance v06, Mobile Portable RF
           Exposure, no SAR required if power is lower than the flowing threshold:
           The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation
           distances ≤ 50 mm are determined by:
            [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)]
            [√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, where
                • f(GHz) is the RF channel transmit frequency in GHz
                • Power and distance are rounded to the nearest mW and mm before calculation25
                • The result is rounded to one decimal place for comparison
                • 3.0 and 7.5 are referred to as the numeric thresholds in the step 2 below

           The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm
           and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test
           separation distance is < 5 mm, a distance of 5 mm according to 5) in section 4.1 is applied to
           determine SAR test exclusion.

3.         Calculation method

           [(max. power of` channel, including tune-up tolerance, mW)/(min. test separation distance,
           mm)] ·[√f(GHz)] ≤ 3.0

For Zigbee

           Radiated Power + tune up tolerance = 7.76 mW
           Distance = 5 mm
           f = 2.44 GHz

           [7.76/5] * SQRT(2.44) =2.424
           2.424 ≤ 3.0

For BLE

           Radiated Power + tune up tolerance = 7.83 mW
           Distance = 5 mm
           f = 2.44 GHz

           [7.83/5] * SQRT(2.44) =2.446
           2.446 ≤ 3.0
