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: FCC Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC rules. 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. To assure continued compliance, any changes or modifications not expressly approved by the party. Responsible for compliance could void the user’s authority to operate this equipment. (Example- use only shielded interface cables when connecting to computer or peripheral devices). This equipment complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation. FCC Radiation Exposure Statement: The equipment complies with FCC Radiation exposure limits set forth for uncontrolled enviroment. This equipment should be installed and operated with minimum distance 20cm between the radiator and your body. .

General Description of EUT EUT Name : Smart gateway Models No. : TYZG1, TYZB1, TYBL1 Model Different : All these models are identical in the same PCB, layout and electrical circuit, The only difference is model name. Product Description : Operation Frequency: 802.11b/g/n(HT20): 2412MHz~2462MHz 802.11n(HT40): 2422MHz~2452MHz Zigbee: 2405MHz~2480MHz Number of Channel: 802.11b/g/n(HT20):11 channels 802.11n(HT40): 7 channels Zigbee:16 channels Antenna Gain: 0dBi PCB Antenna for 2.4G 0dBi PCB Antenna for Zigbee Power Rating : Output: DC 5V/1A Software Version : V2.0.0 Hardware Version : V2.0.0 Connecting I/O Port(S) : : Please refer to the User's Manual Remark : the evaluation report used the EUT(202206-0350-1-2#). Report No.: TBR-C-202206-0350-2 Page: 2 of 3 TB-RF-075-1.0 MPE Calculations for WIFI 1. EUT Operation Condition: Software provided by client enabled the EUT to transmit and receive data at lowest, middle and highest channel individually. 2. Exposure Evaluation: Equation from page 18 of OET Bulletin 65, Edition 97-01 S=(PG)/4πR 2 Where S: power density P: power input to the 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 3. Simultaneous transmission MPE Considerations According to KDB447498: All transmitters and antennas in the host must be either evaluated for MPE compliance, by measurement or computational modeling, or qualify for the standalone MPE test exclusion in section 7.1. Simultaneous transmission MPE test exclusion applies when the sum of the MPE ratios for all simultaneous transmitting antennas incorporated in a host device, based on the calculated/estimated, numerically modeled or measured field strengths or power density, is ≤ 1.0. This means that: ∑ of MPE ratios ≤ 1.0 4.

Conclusion: As specified in Table 1B of 47 CFR 1.1310- Limits for Maximum Permissible Exposure (MPE), Limits for General Population/ Uncontrolled Exposure Frequency Range (MHz) Power density (mW/ cm 2 ) 300-1,500 F/1500 1,500-100,000 1.0 For 2.4WIFI:2412~2462 MHz MPE limit S: 1mW/ cm 2 The MPE is calculated as 0.02006/ cm 2 < limit 1mW / cm 2 . So, RF exposure limit warning or SAR test are not required. The EUT will only be used with a separation of 20cm or greater between the antenna and nearby persons and can therefore be considered a mobile transmitter per 47 CFR2.1091 (b). The RF Exposure Information page from the manual is included here for reference. Note For a more detailed features description, please refer to the RF Test Report. 6. Conclusion: The measurement results comply with the FCC Limit per 47 CFR 2.1091 for the uncontrolled RF Exposure of mobile device. -----END OF REPORT-----
