Product Name

RTL8811CU  Dongle  D211A-WC

Chipset: RTL8811CU


1T1R   USB


Details Information


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.
