Report No.: 1703TW0106-U8 1. PRODUCT INFORMATION 1.1. Equipment Description Product Name: ACCESS POINT Model No.: APINH203 Brand Name: , Software Version: 9.10 RC178.40 Operating Temperature: 0 ~ 40 °C Power Type: POE input Wi-Fi Specification: 802.11a/b/g/n/ac Note: The applicant has provided one POE adapter (Manufacturer: MICROSEMI & Model: PD-9001GR/AT/AC & Output: 55VDC, 0.6A) for approval testing and it is not for sale. 1.2. Antenna Description Antenna Type Frequency Band TX Paths Max Antenna Gain Directional Gain (MHz) (dBi) (dBi) 1 (Note 3) 4.3 N/A 2412 ~ 2462 PCB 2 3.8 6.8 Antenna 1 (Note 3) 6.3 N/A 5150 ~ 5850 2 4.0 7.0 Note 1: The EUT supports Cyclic Delay Diversity (CDD) technology for 802.11a/b/g/n/ac mode, and the transmitter output signal is correlated. For CDD transmissions, directional gain = GANT + Array Gain, Array Gain = 3.0 dBi which is declared by the applicant. For power measurements on IEEE 802.11 devices, Array Gain = 0 dB for NANT ≤ 4. Note 2: The EUT also supports Beam Forming technology, and the Beam Forming only support 802.11n/ac mode. Directional gain = GANT + BF Gain, BF Gain = 3.0 dBi which is declared by the applicant. Note 3: For SISO mode, only Ant 2 port can transmit 2.4GHz and Ant 1 port can transmit 5GHz. FCC ID: Q9DAPINH203 Page Number: 3 of 5

Report No.: 1703TW0106-U8 2. RF Exposure Evaluation 2.1. Limits According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environment impact of human exposure to radio frequency (RF) radiation as specified in 1.1307(b) LIMITS FOR MAXIMUM PERMISSIBLE EXPOSURE (MPE) Frequency Range Electric Field Magnetic Field Power Density Average Time 2 (MHz) Strength (V/m) Strength (A/m) (mW/cm ) (Minutes) (A) Limits for Occupational/ Control Exposures 300-1500 -- -- f/300 6 1500-100,000 -- -- 5 6 (B) Limits for General Population/ Uncontrolled Exposures 300-1500 -- -- f/1500 6 1500-100,000 -- -- 1 30 f= Frequency in MHz Calculation Formula: Pd = (Pout*G)/(4*pi*r2) Where Pd = power density in mW/cm2 Pout = output power to antenna in mW G = gain of antenna in linear scale Pi = 3.1416 r = distance between observation point and center of the radiator in cm Pd is the limit of MPE, 1mW/cm². If we know the maximum gain of the antenna and the total power input to the antenna, through the calculation, we will know the distance r where the MPE limit is reached.

Report No.: 1703TW0106-U8 2.2. Test Result of RF Exposure Evaluation Product ACCESS POINT Test Item RF Exposure Evaluation Antenna Gain: Refer to clause 1.2. Test Mode Frequency Band Maximum Average Power Density at Limit (MHz) Output Power R = 20 cm (mW/cm2) (dBm) (mW/cm2) 802.11b/g/n SISO 2412 ~ 2462 17.08 0.0273 1 802.11b/g/n MIMO 2412 ~ 2462 20.22 0.0502 1 5180 ~ 5320 802.11a/n/ac SISO 5500 ~ 5720 16.87 0.0413 1 5745 ~ 5825 5180 ~ 5320 802.11a/n/ac MIMO 5500 ~ 5720 19.98 0.0497 1 5745 ~ 5825 CONCULISON: Both of the WLAN 2.4GHz Band and WLAN 5GHz Band can transmit simultaneously. Therefore, the Max Power Density at R (20 cm) = 0.0273mW/cm2+ 0.0413mW/cm2 = 0.0686mW/cm2 < 1mW/cm2. So the EUT complies with the requirement. The End FCC ID: Q9DAPINH203 Page Number: 5 of 5
