1. General Description
1.1. RTL8188CE
The Realtek RTL8188CE is a highly integrated single-chip Wireless LAN (WLAN) controller compatible
with the IEEE 802.11n specification. It combines a MAC, a 1T1R capable baseband, and RF in a single
chip. The RTL8188CE provides a complete solution for a high-performance wireless client.
The RTL8188CE baseband implements Multiple Input, Multiple Output (MIMO) Orthogonal Frequency
Division Multiplexing (OFDM) 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 both
20MHz and 40MHz channel bandwidth.
For legacy compatibility, Direct Sequence Spread Spectrum (DSSS), Complementary Code Keying (CCK)
and OFDM baseband processing are included to support all IEEE 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 IEEE 802.11g and 802.11n OFDM respectively.
The RTL8188CE 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.
Efficient IQ-imbalance, DC offset, phase noise, frequency offset, and timing offset compensations are
provided for the radio frequency front-end. Selectable digital transmit and receive FIR filters are provided
to meet transmit spectrum mask requirements and to reject adjacent channel interference, respectively.
The RTL8188CE 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 RTL8188CE 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 U-APSD,
and APSD, reduces power wasted during idle time, and compensates for the extra power required to
transmit OFDM. The RTL8188CE-GR provides simple legacy and 20MHz/40MHz co-existence
mechanisms to ensure backward and network compatibility.
1.2. BlueCore4-ROM
CSR BlueCore4-ROM is a single-chip radio and baseband IC for Bluetooth 2.4GHz systems including
enhanced data rates (EDR) to 3Mbps. With the on-chip CSR Bluetooth software stack it provides a fully
compliant Bluetooth system to v2.1 of the specification for data and voice communications.

2.7. Warning
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.
This transmitter must not be co-located or operating in conjunction with any other antenna 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,
As long as 3 conditions above are met, further transmitter test will not be required. However, the OEM
