Introduction
This document provides a guideline for the execution of the FCC radio certification tests of Zigbee / Matter™/
Bluetooth Low Energy modules using QPG6105 chips. This document focusses on Bluetooth Low Energy
mode certification for the FCC regulatory domain.
At start of the radio certification test the applicable PHY (BLE) can be selected in the Radio Control Console
software [1].
This document is based on, and aligned with, the technical requirements given in CFR 47 PART 15, Section
15.247 “Operation within the bands 902 - 928 MHz, 2400 - 2483.5 MHz, and 5725 - 5850 MHz”.
