Report No.: 1808RSU004-U7 1. PRODUCT INFORMATION 1.1. Equipment Description Product Name AX6000 MU-MIMO Wi-Fi Router Model No. Archer AX6000 Brand Name: tp-link Wi-Fi Specification: 802.11a/b/g/n/ac/ax Bluetooth Specification: v4.1 dual mode Components Adapter MODEL: S050FU1200400 INPUT: 100 - 240V ~ 50/60Hz 1.5A Max. OUTPUT: DC 12.0V 4000mA 1.2. Description of Available Antennas Antenna Type Frequency TX Max Antenna BF Directional CDD Directional Gain (dBi) Band (MHz) Paths Gain (dBi) Gain (dBi) For Power For PSD Wi-Fi External Antenna 2412 ~ 2462 4 1.16 7.18 1.16 7.18 Dipole Antenna 5150 ~ 5850 4 2.28 8.30 2.28 8.30 Bluetooth Internal Antenna PCB Antenna 2402 ~ 2480 1 4.05 -- -- -- Note: 1. The EUT supports Cyclic Delay Diversity (CDD) mode, and CDD signals are correlated. For CDD transmissions, directional gain is calculated as follows, NANT = 4, NSS = 1. If all antennas have the same gain, GANT, Directional gain = GANT + Array Gain, where Array Gain is as follows. • For power spectral density (PSD) measurements on all devices, Array Gain = 10 log (NANT/ NSS) dB = 6.02; • For power measurements on IEEE 802.11 devices, Array Gain = 0 dB for NANT ≤ 4; 2. The EUT also supports Beam Forming mode, and the Beam Forming support 802.11ac/ax, not include 802.11a/b/g/n. BF Directional gain = GANT + 10 log (NANT). FCC ID: TE7AX6000 Page Number: 3 of 7

Report No.: 1808RSU004-U7 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.: 1808RSU004-U7 2.2. Test Result of RF Exposure Evaluation Product AX6000 MU-MIMO Wi-Fi Router Test Item RF Exposure Evaluation Antenna Gain: Refer to clause 1.2. Test Mode Frequency Band Max Conducted Antenna Gain Maximum EIRP (MHz) Power (dBi) (dBm) (dBm) BT 2402 ~ 2480 8.67 4.05 12.72 802.11b/g/n/ac/ax 2412 ~ 2462 28.80 7.18 35.98 5180 ~ 5320, 802.11 a/n/ac/ax 5500 ~ 5720, 27.56 8.30 35.86 5745 ~ 5825 Test Mode Frequency Band Maximum EIRP Power Density Limit Power Density at (MHz) (dBm) at (mW/cm2) R = 25 cm R = 20 cm (mW/cm2) (mW/cm2) Bluetooth 2402 ~ 2480 12.72 0.0037 1 0.0024 802.11b/g/n/ac/ax 2412 ~ 2462 35.98 0.7884 1 0.5046 5180 ~ 5320, 802.11a/n/ac/ax 5500 ~ 5720, 35.86 0.7669 1 0.4908 5745 ~ 5825 CONCULISON: Both of the WLAN 2.4GHz Band, WLAN 5GHz Band and Bluetooth Band can transmit simultaneously. The max Power Density at R (20 cm) = 0.0037mW/cm2 + 0.7884mW/cm2 + 0.7669mW/cm2 = 1.5590mW/cm2 < 1mW/cm2. The max Power Density at R (25 cm) = 0.0024mW/cm2 + 0.5046mW/cm2 + 0.4908mW/cm2 = 0.9978mW/cm2 < 1mW/cm2. Therefore, the Min Safety Distance is 25cm. The End FCC ID: TE7AX6000 Page Number: 5 of 7
