General Description

The RTL8192ES is a highly integrated single-chip 802.11n Wireless LAN (WLAN) network

controller with SDIO interface (SDIO 1.1/ 2.0/ 3.0 compliant). It combines a WLAN MAC, a 2T2R

capable WLAN baseband, and WLAN RF in a single chip. The RTL8192ES provides a complete

solution for a high throughput performance integrated wireless LAN device.

The RTL8192ES WLAN baseband implements Orthogonal Frequency Division Multiplexing (OFDM)

with 2 transmit and 2 receive paths and is compatible with the 802.11n specification. It features two

spatial stream transmission, short guard interval (GI) of 400ns, spatial spreading, and transmission over

20MHz and 40MHz bandwidth

For legacy compatibility, Direct Sequence Spread Spectrum (DSSS), Complementary Code Keying

(CCK) and OFDM baseband processing are included to support all 802.11b and 802.11g data rates.

Differential phase shift keying modulation schemes, DBPSK and DQPSK with data scrambling

capability, are available, and CCK provides support for legacy data rates, with long or short preamble.

The high-speed FFT/IFFT paths, combined with BPSK, QPSK, 16QAM, and 64QAM modulation of

the individual subcarriers and rate compatible punctured convolutional coding with coding rate of 1/2,

2/3, 3/4, and 5/6, provide higher data rates of 54Mbps and 150Mbps for 802.11g and 802.11n OFDM

respectively.

The RTL8192ES WLAN Controller 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. Robust interference detection and suppression are

provided to protect against Bluetooth, cordless phone, and microwave oven interference

The RTL8192ES WLAN Controller supports fast receiver Automatic Gain Control (AGC) with

synchronous and asynchronous control loops among antennas, antenna diversity functions, and

adaptive transmit power control function to obtain the better performance in the analog portions of the

transceiver.

The RTL8192ES WLAN MAC supports 802.11e for multimedia applications, 802.11i for security, and

802.11n for enhanced MAC protocol efficiency. Using packet aggregation techniques such as

A-MPDU with BA and A-MSDU, protocol efficiency is significantly improved. Power saving

mechanisms such as Legacy Power Save, and U-APSD, reduce the power wasted during idle time, and

compensates for the extra power required to transmit OFDM. The RTL8192ES provides simple legacy

and 20MHz/40MHz co-existence mechanisms to ensure backward and network compatibility
