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”.
