1. General Description
The Realtek RTL8192E miniCard is a highly integrated MIMO wireless LAN (WLAN) used for high speed
wireless local network access. The card is built with a MAC and 1T2R capable baseband chip RTL8192E
with an RF IC RTL8256.
The RTL8192E miniCard implements multiple input, multiple output (MIMO) orthogonal frequency
division multiplexing (OFDM) with 1 transmit and 2 receive paths and is compatible with 802.11n Draft
specification 2.0. Other features include two spatial streams transmission, short guard interval (GI) of
400ns, spatial spreading, and transmission over 20 MHz and 40 MHz bandwidth. Moreover, RTL8192E
provides one spatial stream space-time block code (STBC) to extend the range of transmission. At the
receiver, extended range and good minimum sensitivity is achieved by having receiver diversity up to 2
antennas. As the recipient, the RTL8192E miniCard 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 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 RTL8192E PCI-E miniCard 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
U-APSD, APSD, and MIMO power saving reduces the power wasted during idle time, and compensates for
the extra power required to transmit MIMO OFDM. The RTL8192E PCI-E miniCard provides simple
legacy and 20Mhz/40Mhz co-existence mechanisms to ensure backward and network compatibility.

Federal Communication Commission Interference Statement
This equipment has been tested and found to comply with t he li mits 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 t o 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.
This transmitter must not be co-located or operating in conjunction with any other an tenna or transmitter.
IEEE 802.11b or 802.11g operation of this product in the U.S.A. is firmware-limited to channels 1 through 11.
This device is intended only for OEM integrators under the following conditions:
The antenna must be installed such that 20 cm is maintained between the antenna and users, and
The transmitter module may not be co-located with any other transmitter or antenna,
For all products market in US, OEM has to limit the operation channels in CH1 to CH11 for 2.4G band by supplied firmware
programming tool. OEM shall not supply any tool or info to the end-user regarding to Regulatory Domain change.
10 Rev.1.0
RTL8192E
As long as 3 conditions above are met, further transmitter test will not be required. However, the OEM integrator is still
responsible for testing their end-product for any additional compliance requirements required with this module installed (for
example, digital device emissions, PC peripheral requirements, etc.).
IMPORTANT NOTE: In the event that these condi tions can not be met (for exam ple certain laptop confi gurations or co-location
with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID can not be used on the final
product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the
transmitter) and obtaining a separate FCC authorization.
End Product Labeling
This transmitter module is authorized only for use in device where the antenna may be installed such that 20 cm may be
maintained between the antenna and users. The final end product must be l abeled in a vi sible area with t he following: “Cont ains
FCC ID: TX2-RTL8192E”.
Manual Information To the End User
The OEM integrator has to be aware not to provide information to the end user regarding how to i nstall or remove this RF module
in the user’s manual of the end product which integrates this module.
