These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: - Reorient or relocate the receiving antenna. - Increase the separation between the equipment and receiver. -Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. -Consult the dealer or an experienced radio/TV technician for help. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.

PRODUCT INFORMATION FCC ID 2AKC6-RTL802 Product Description Bluetooth USB Adapter Model Name RTL802, RTL812, RTL806, RTL804 Frequency Band (Operating) WLAN: 2.412GHz ~ 2.462GHz WLAN: 5.18GHz ~ 5.32GHz / 5.50GHz ~ 5.70GHz WLAN: 5.745GHz ~ 5825GHz Bluetooth: 2.402GHz ~ 2.480GHz Others Device Category Portable (<20cm separation) Mobile (>20cm separation) Others: Antenna Diversity Single antenna Multiple antennas Max. Output Power BT_BR:3.160dBm (Max) BT_BLE:6.729dBm (Max) Antenna Designation PCB Antenna Antenna Gain 2.97dBi Minimum Assessment Distance 5mm Evaluation Applied MPE Evaluation SAR Evaluation Evaluation Result Pass 2. PORTABLE DEVICE EVALUATION METHOD AND LIMIT Following FCC KDB 447498 D01 “General SAR test exclusion guidance” The corresponding SAR Exclusion Threshold condition, listed below: 1) 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)] [if(GHz)] s 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 calculation.  The result is rounded to one decimal place for comparison 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 is applied to determine SAR test exclusion. 2) At 100 MHz to 6 GHz and for test separation distances > 50 mm, the SAR test exclusion threshold is determined according to the following: a) [Threshold at 50 mm in step 1) + (test separation distance - 50mm) ( f(MHz)/150)] mW, at 100MHz to 1500 MHz; b) [Threshold at 50 mm in step 1) + (test separation distance - 50 mm)-10] mW at > 1500 MHz and ≤6 GHz; 3) At frequencies below 100 MHz, the following may be considered for SAR test exclusion. a) The threshold at the corresponding test separation distance at 100 MHz in step 2) is multiplied by [1 + log(100/f(MHz))] for test separation distances > 50 mm and < 200 mm. b) The threshold determined by the equation in a) for 50 mm and 100 MHz is multiplied by 1/2 for test separation distances ≤50 mm. c) SAR measurement procedures are not established below 100 MHz. When SAR test exclusion cannot be applied, a KDB inquiry is required to determine SAR evaluation requirements for any test results to be acceptable. 3. MOBILE DEVICE EVALUATION METHOD AND LIMIT Human exposure to RF emissions from mobile devices (47 CFR §2.1091) may be evaluated based on the MPE limits adopted by the FCC for electric and magnetic field strength and/or power density, as appropriate, since exposures are assumed to occur at distances of 20 cm or more from persons. LIMITS FOR GENERAL POPULATION / UNCONTROLLED EXPOSURE Frequency Range (MHz) E-field Strength (E) (V/m) Magnetic Field Strength (H) (A/m) Power Density (S) (mW/cm 2 ) Averaging Time |E| 2 , |H| 2 or S (Minutes) 0.3 -- 1.34 614 1.63 (100)* 30 1.34 -- 30 824/f 2.19/f (180/f 2 )* 30 30 -- 300 27.5 0.073 0.2 30 300 -- 1500 -- -- f/1500 30 1500 -- 100,000 -- -- 1.0 30 *Note: 1. f= Frequency in MHz * Plane-wave Equivalent Power Density 2. The averaging time for General Population/Uncontrolled exposure to fixed transmitters is not applicable for mobile and portable transmitters. See 47 CFR §§2.1091 and 2.1093 on source-based time-averaging requirement for mobile and portable transmitters. S=PG/4πR² Where: S=power density P=power input to antenna G=power gain of the antenna in the direction of interest relative to an isotropic radiator R=distance to the center of radiation of the antenna 4.

Fox example: 4.709/5*√2.402=1.460 ≤ 3.0 According to KDB447498 D01 V06, threshold at which no SAR required is ≤3.0 for 1-g SAR, separation distance is 5mm, and no simultaneous SAR measurement is required. 5. CONCLUSION Since Source-base time average power is below SAR test exclusion power thresholds, the SAR evaluation is not required.
