1. Introduction

1.1 General Description

BL-M8822CU1 is a highly integrated module that was built in a 2*2 dual-band wireless LAN radio and

Bluetooth radio. It combines a WLAN MAC, a 2T2R capable WLAN base band, and RF in a single chip. It

supports IEEE 802.11a/b/g/n/ac standard and provides the highest PHY rate up to 867Mbps, offering feature-

rich wireless connectivity and reliable throughput from an extended distance.
