This document presents the Maximum Permissible Exposure (MPE) calculation report for the Hangzhou Tuya Information Technology Co., Ltd.'s Wi-Fi and Bluetooth Module, model number TYCH01. The report ensures compliance with FCC guidelines regarding radio frequency energy exposure, as outlined in subpart 15.247(i) and §1.1307(b)(1).
The MPE limits for general population/uncontrolled exposure are detailed, referencing KDB 447498 D01, §1.1310, and §2.1091. The report includes calculations for power density at a given distance, considering power input to the antenna and antenna gain. The calculated power densities for both Wi-Fi and Bluetooth Low Energy (BLE) modes are below the MPE limits, indicating compliance.
Specifically, the maximum power density for Wi-Fi is 0.1235 mW/cm², and for BLE, it is 0.0011 mW/cm², both well below the limit of 1.0 mW/cm². The report also notes that simultaneous transmission of Wi-Fi and BLE is not supported, as they share the same antenna. This report was prepared and reviewed by TÜV SÜD Certification and Testing (China) Co., Ltd. Shanghai Branch.
