RTL8811CU  Wi-Fi Dongle  D211A-WC

1.Introduction  The Realtek D211A-WC is a highly-integrated IEEE 802.11 a/b/g/n/ac MAC/Baseband/RF WLAN 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.  D211A-WC baseband implements multiuser Multiple-Input Multiple-Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) STA mode with one transmit and one receive path (1T1R). Features include one spatial stream transmission, short Guard Interval (GI) of 400ns, spatial spreading, and support for variant channel bandwidths. Moreover, RTL8811CU-CG provides one spatial stream Space-Time Block Code (STBC) and Low Density Parity Check (LDPC) to extend the range of transmission. As the recipient, the RTL8811CU-CG also supports explicit sounding packet feedback that helps senders with beamforming capability.  This compact module is a total solution for a combination of Wi-Fi technologies. The module is specifically developed for Smart phones and Portable devices.    2.Features  General Features CMOS MAC, Baseband PHY and RF in a single chip for IEEE 802.11a/b/g/n/ac compatible WLAN Support 802.11ac 1x1,Wave-2 compliant with MU-MIMO STA mode Complete 802.11n MIMO solution for 2.4GHz and 5Ghz band Maximum PHY data rate up to 86.7Mbps using 20MHz bandwidth, 200Mbps using 40MHz bandwidth, and 433.3Mbps using 80MHz bandwidth.
