For the purpose of marketing, the frequency of the product sold in U.S. are programmed and lo cked to work only in 5150 MHz~5250MHz, 5725MHz~5850MHz , The other frequency bands 5250MHz~5350MHz, 5470MHz~ 5725MHz are disabled by firmware in factory. The end user or any other parties cannot have the capability to activate the other frequency bands. We applied for testing only frequency bands: 2412~2462MHz ,2422~2452MHz and 5180~5240MHz, 5745~5825MHz for the United States this time in BACL. Please contact me if you have any question.

Limits for Maximum Permissible Exposure (MPE) (§1.1310, §2.1091) (B) Limits for General Population/Uncontrolled Exposure Frequency Range (MHz) Electric Field Strength (V/m) Magnetic Field Strength (A/m) Power Density (mW/cm 2 ) Averaging Time (minutes) 0.3–1.34 614 1.63 *(100) 30 1.34–30 824/f 2.19/f *(180/f²) 30 30–300 27.5 0.073 0.2 30 300–1500 / / f/1500 30 1500–100,000 / / 1.0 30 f = frequency in MHz; * = Plane-wave equivalent power density; According to §1.1310 and §2.1091 RF exposure is calculated. Calculation formula: Prediction of power density at the distance of the applicable MPE limit S = PG/4R² = power density (in appropriate units, e.g. mW/cm 2 ); P = power input to the antenna (in appropriate units, e.g., mW); G = power gain of the antenna in the direction of interest relative to an isotropic radiator, the power gain fac vhtor, is normally numeric gain; R = distance to the center of radiation of the antenna (appropriate units, e.g., cm); For simultaneously transmit system, the calculated power density should comply with: Bay Area Compliance Laboratories Corp. (Dongguan) Report No.: RDG201126003-00B Page 14 of 87 Calculated Data: Mode Frequency (MHz) Antenna Gain Conducted output power including Tune- up Tolerance Evaluation Distance (cm) Power Density (mW/cm 2 ) MPE Limit (mW/cm 2 ) (dBi) (numeric)(dBm)(mW) WLAN 2412-2462 7.2 5.25 29 794.33 25.00 0.53 1.0 WLAN 5150-5250 7 5.01 22 158.49 25.00 0.10 1.0 WLAN 5725-5850 7 5.01 23 199.53 25.00 0.13 1.0 Note: the antenna gain is add beamforming gain. The maximum EIRP was used for calculation. The WLAN 2.4G and 5G can transmit simultaneously: =S 2.4 /S limit-2.4 + S 5 /S limit-5 =0.53/1+0.13/1 =0.66 < 1.0 Result: The device meet FCC MPE at 20 cm distance
