2. GENERAL FEATURES ......................................................................................................................................................5
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 input, m ultiple output (MIMO) orthogonal frequency
division multiplexing (OFDM) with 2 transmit and 2 receive paths and is com patible with 802.11n Draft
specification 2.0. Other features include two spatial streams transm ission, Long guard interval (GI) of
800ns, spatial spreading, and transmission over 20 MHz and 40 MHz bandwidth. Moreover, RTL8192CE
provides one spatial stream space-tim e 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, 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, 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.
4.5.1 Federal Communication Commission Interference Statement
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that
to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation.
FCC Caution: Any changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate this equipment.
IMPORTANT NOTE:
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment.
This equipment should be installed and operated with minimum distance 20cm between the radiator & your
body.

IMPORTANT NOTE:
This module is intended for OEM integrator. The OEM integrator is still responsible for the FCC compliance
requirement of the end product, which integrates this module.
20cm minimum distance has to be able to be maintained between the antenna and the users for the host this
module is integrated into. Under such configuration, the FCC radiation exposure limits set forth for an
population/uncontrolled environment can be satisfied.
Any changes or modifications not expressly approved by the manufacturer could void the user's authority to operate
this equipment.
USERS MANUAL OF THE END PRODUCT:
In the users manual of the end product, the end user has to be informed to keep at least 20cm separation with the
antenna while this end product is installed and operated. The end user has to be informed that the FCC
radio-frequency exposure guidelines for an uncontrolled environment can be satisfied. The end user has to also be
informed that any changes or modifications not expressly approved by the manufacturer could void the user's
authority to operate this equipment. If the size of the end product is smaller than 8x10cm, then additional FCC part
15.19 statement is required to be available in the users manual: This device complie with Part 15 of FCC rules.
Operation is subject to the following two conditions: (1) this device may not cause harmful interference and (2) this
device must accept any interference received, including interference that may cause undesired operation.
LABEL OF THE END PRODUCT:
The final end product must be labeled in a visible area with the following " Contains TX FCC ID: TX2-RTL8192CED
". If the size of the end product is larger than 8x10cm, then the following FCC part 15.19 statement has to also be
