General Description
The Realtek RTL8811CU-CG 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.
The RTL8811CU-CG 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.
For legacy compatibility, Direct Sequence Spread Spectrum (DSSS), Complementary Code Keying (CCK)
and OFDM baseband processing are included to support all IEEE 802.11a, 802.11b and 802.11g data rates.
Differential phase shift keying modulation schemes, DBPSK and DQPSK with data scrambling capability,
are available. CCK provides support for legacy data rates, with long or short preamble. The high speed
FFT/IFFT paths are combined with BPSK, QPSK, 16QAM, 64QAM and 256QAM modulation of the
individual subcarriers. The compatible coding rate of 1/2, 2/3, 3/4, and 5/6 provides up to 433.3Mbps for
IEEE 802.11ac with MIMO-OFDM.
The RTL8811CU-CG builds in an enhanced signal detector, an adaptive frequency domain equalizer, and a
soft-decision Viterbi decoder to alleviate severe multi-path effects and mutual interference in the reception
of multiple streams.
Receive vector diversity for multi-stream application is implemented for efficient utilization of the MIMO
channel. Efficient IQ-imbalance, DC offset, phase noise, frequency offset, and timing offset compensations
are provided for the radio frequency front-end.
The RTL8811CU-CG supports fast receiver Automatic Gain Control (AGC) with synchronous and
asynchronous control loops among antennas, antenna diversity functions, and adaptive transmit power
control functions to obtain better performance in the analog portions of the transceiver.
The RTL8811CU-CG MAC supports 802.11e for multimedia applications, 802.11i and WAPI (Wireless
Authentication Privacy Infrastructure) for security, and 802.11n/ac for enhanced MAC protocol efficiency.
Protocol efficiency is significantly improved by using packet aggregation techniques, such as A-MPDU
with BA and A-MSDU. Power saving mechanisms, such as Legacy Power Save, U-APSD, and MIMO, can
reduce the power wasted during idle time. They can also compensate for the extra power required to
