1. General Description
AzureWave Technologies, Inc. introduces the pioneer of the IEEE 802.11 a/b/g/n/ac WIFI with
Bluetooth 4.2 combo M.2 module --- AW-CM308NF. The AW-CM308NF IEEE 802.11 a/b/g/n/ac PCIE
WIFI with Bluetooth 4.2 combo M.2 module is a highly integrated single-chip MIMO (Multiple In, Multiple
Out) wireless local area network (WLAN) solution to let users enjoy the digital content through the latest
wireless technology without using the extra cables and cords. It combines a WLAN MAC, a 2T2R
capable WLAN baseband, and RF in s single chip. It enables a high performance, cost effective, low
power, compact solution that easily fits onto the PCI Express and USB M.2 module.
The AW-CM308NF baseband implements Multi-user Multiple Input, Multiple Output (MU-MIMO)
Orthogonal Frequency Division Multiplexing (OFDM) with two transmit and two receive paths (2T2R).
Features include two spatial stream transmissions, short Guard Interval (GI) of 400ns, spatial spreading,
and support for variant channel bandwidth. Moreover, AW-CM308NF provides one spatial stream space-
time block code (STBC), Transmit Beamforming (TxBF) and Low Density Parity Check (LDPC) 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 AW-CM308NF 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 IEEE 802.11b, 802.11g and 802.11a
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, 64QAM and 256QAM
modulation of the individual subcarriers, and rate compatible coding rate of 1/2, 2/3, 3/4, and 5/6, provide
up to 866.7Mbps for IEEE 802.11ac MIMO OFDM.
The RTL8822BE-CG 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. For better detection quality, receive diversity with Maximal-Ratio-Combine
(MRC) applying up to two receive paths is implemented. Robust interference detection and suppression
are provided to protect against Bluetooth, cordless phone, and microwave oven interference.
Receive vector diversity for multi-stream application is implemented for efficient utilization of the MIMO
channel. Efficient IQ-imbalance, DC offset, phase noise, frequency offset, and timing offset
compensations are provided for the radio frequency front-end.

5.3 LED mode behavior
State Definition Interpretation
OFF The LED is emitting no
light.
Radio is incapable of transmitting.
This state is indicated when the card is not powered, the
W_Disable# signal is asserted to disable the radio, or when the
radio is disabled by software.
ON The LED is emitting
light.
Radio is capable of transmitting.
The LED should remain ON even if the radio is bit actually
transmitting. For example, the LED remains ON during
temporary radio disablements performed by the Mini Card of its
own volition to do scanning, switching radios/bands, power-
management, etc.
If the card is in a state wherein it is possible that radio can begin
transmitting without the system user performing any action, this
LED should remain ON.

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.
FCC Caution: To assure continued compliance, any changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to operate this equipment. (Example - use only shielded
interface cables when connecting to computer or peripheral devices).
End Product Labeling
This transmitter module is authorized only for use in devices where the antenna may be installed such that 20 cm
may be maintained between the antenna and users. The final end product must be labeled in visible area with the
following: “Contains FCC ID: TLZ-CM308NF”
”
End Product Manual Information
The user manual for end users must include the following information in a prominent location “IMPORTANT NOTE:
To comply with FCC RF exposure compliance requirements, the antenna used for this transmitter must be installed
to provide a separation distance of at least 20cm from all persons and must not be colocated or operating in
conjunction with any other antenna or transmitter.” 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.
IMPORTANT NOTE: In the event that these conditions can not be met (for example certain laptop configurations
or colocation 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
reevaluating the end product (including the transmitter) and obtaining a separate FCC authorization. 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. As long as a condition above is 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.).
