RTL8192CE MINICARD MECHANICAL SPECIFICATION................................................................................................8 iii Rev.1.0 1. General Description RTL8192CE Users Manual The Realtek RTL8192CE m iniCard is a highly integr ated MIMO wireless LAN (W LAN) used for high speed wireless local network access. The card is built with a MAC and 2T2R capable RF/baseband single chip RTL8192CE. The RTL8192CE m iniCard im plements m ultiple i nput, m ultiple output (MIMO) orthogonal frequency division multiplexing (OFDM) with 2 transm it and 2 receive paths and is com patible with 802.11n Draft specification 2.0. Other features include two spatial streams transmission, Long guard interval (GI) of 800ns, spatial spreading, and transmission over 20 MHz and 40 MHz bandwidth. Moreover, RTL8192CE provides one spatial stream space-time block code (S TBC) to extend the range of transm ission. At the receiver, extended range and good m inimum sensitivity is achieved by having receiver diversity up to 2 antennas. As the recipient, the RTL8192CE miniCard also supports explicit sounding packet feedback that helps senders with beamforming capability. For legacy com patibility, direct sequence spread spectrum (DSSS), com plementary 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 along with complementary code keying to provide the data rates of 1, 2, 5.5 and 11Mbps with long or short preamble. The high speed FFT/IFFT paths, com modulation of the individual subcarriers and rate compatible punctured convolutional coding with coding rate of 1/2, 2/3, 3/4, and 5/6, provides the maximum data rate of 54 Mbps and 300 Mbps for IEEE 802.11g and 802.11n MIMO OFDM respectively. The RTL8192CE PCI-E miniCard supports 802.11e for multimedia applications, 802.11i for security, and 802.11n for enhanced MAC protocol e fficiency. Using packet aggrega tion techniques such as A-MPDU with BA and A-MSDU, protocol efficiency is signi ficantly improved. Power saving mechanisms such as U-APSD, APSD, and MIMO power saving reduces the power wasted during idle time, and compensates for the extra power required to transm it MIMO OFDM . The RTL8192CE PCI-E m iniCard provides sim ple legacy and 20Mhz/40Mhz co-existence mechanisms to ensure backward and network compatibility. bined with BPSK, QPSK, 16QAM, and 64QAM 4 Rev.1.0 RTL8192CE Users Manual Complies with PCI Express Base Specification Revision 1.1 IEEE standards support: IEEE 802.11b, 802.11g, draft 802.11n Mini PCI Express interface Enterprise level security which can apply WPA2 certification 2 transmitter and 2 receivers allow data rates supporting up to 300 Mbps downstream and 300 Mbps Full-featured software utility for easy configuration and management Power savings features and low power consumptions for mobile powered applications Rohs compliance 2.
