1. General Description The RTL8821CU-CG is a highly-integrated IEEE 802.11 a/b/g/n/ac MAC/Baseband/RF WLAN and Bluetooth Baseband/RF single chip. For Wireless LAN (WLAN) operation, it supports 1-stream 802.11ac solution with Multi-user MIMO (Multiple-Input, Multiple-Output) STA mode with USB2.0 network interface controller. For Bluetooth operation, it supports Bluetooth 2.1/4.2 with USB interface controller.

network compatibility. The RTL8821CU-CG Bluetooth controller complies with Bluetooth core specification v4.2, and supports dual mode (BR/EDR + AMP + Low Energy Controllers). It is backward compatible with previous versions including v2.1 + EDR and v3.0 + HS. For BR/EDR, it can support scatternet topology up to four active links in slave mode, and seven active links in master mode. For Low Energy, it supports multiple states and allows eight active links in master mode.
