module integration
1 Purpose
The purpose of this document is to provide information on how to install the AW-AU397
module in B&O products.
The AW-AU397 W-LAN module is only intended for integration into end host products by
B&O authorised personnel only. Incorrect integration or use may infringe compliance rule
meaning recertification is required.
2 Module description
The module is an IEEE 802.11a/b/g/n 2X2 MIMO WLAN & Bluetooth module based on a
Marvell chip. The module is designed to be plugged into a Mini PCI-E 52P connector, which
contains all the interfaces and power connection. Additional the module has two UFL
antenna connectors. See picture below.
3 Integration in B&O products
The AW-AU397 module will be integrated in both audio and video products from B&O. A
similar Mini PCI-E connector is used as interface and the antennas inside the product are
connected to the UFL connectors at the module.
3.1 Module Integration Details
Use the respective B&O build/assembly instructions for mounting and connecting the module
into each B&O product type. This will ensure correct working of the module and will ensure it
will not be collocated with any other transmitter/antenna if these instructions are followed.
3.2 Audio Devices
In B&O audio products the AW-AU397 module can be installed in two different ways:
1. Stand-alone integration
2. Audio Streaming Engine mounted
An example of stand-alone integration is shown in the following photos with the AW-AU397
module integrated in the BeoSound Moment end product:
An example of the Audio Streaming Engine integration is shown in the following photo:
3.3 Audio Device Antennas
The AW-WU397 module when integrated into Audio Devices will use the Tyco Puck
antenna, part no.1513472-5, with a frequency range of 2,400 - 2,483.5 MHz & 5,150-5,875
MHz and peak gain of +3 dBi.
If other radio systems are integrated in the product, it is required to keep minimum 20cm
separation distance between any antenna from other radios and each of the antennas
connected to AW-WU397.
The module must not be integrated in portable devices to be used in direct contact with the
body of the user or within 20cm of the body of the user under normal operating conditions.
3.4 Video Devices
In Video Devices the AW-AU397 module will be mounted on a small interface board with a
cable connection to the Video Engine. The interface board provides good flexibility for
placing the module in an optimum position keeping antenna cables short. See picture.
3.4.1 Video Device Antenna
The AW-AU397 module when integrated into video products will use the B&O BO AirWire
antenna with a frequency range of 2,400-2,483.5 MHz & 5,150-5,875 MHz and a peak gain
of +4.2 dBi.
If other radio systems are integrated in the product, it is required to keep minimum 20cm
separation distance between any antenna from other radios and each of the antennas
connected to AW-WU397.
The module must not be integrated in portable devices to be used in direct contact with the
body of the user or within 20cm of the body of the user under normal operating conditions.
4 End Product Labelling
A label is to be fitted to the exterior of all products containing the AW-AU397 module. The
label must include the words “Contains FCC ID: TTUAW-AU397” (for FCC) or “Contains IC:
3775B-AWAU397” (for IC).
Examples of B&O Audio and Video product labels and placement locations are in the
following sections.

4.1.2 Location
4.2 BeoVision Avant:
4.2.1 Label

FCC Compliance
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 module must not be co-located or operating in conjunction with any other antenna or
transmitter.
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
antenna & user’s body. In the United States, operation on channels 36-48 in the 5150-5250
MHz band is restricted to indoor-use only.
If the FCC ID of the module is not visible when installed in the intended host equipment, then
a permanently attached or marked label must be displayed on the exterior of the host
equipment referring to the module FCC ID.
Industry Canada Compliance
This device complies with Industry Canada licence-exempt RSS standard(s). Operation is
subject to the following two conditions:
(1) this device may not cause interference, and (2) this device must accept any
interference, including interference that may cause undesired operation of the device.
Under Industry Canada regulations, this radio transmitter may only operate using an antenna
of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To
reduce potential radio interference to other users, the antenna type and its gain should be so
chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that
necessary for successful communication.
This radio transmitter (IC ID: 3775B-AWAU397) has been approved by Industry Canada to
operate with the antenna types listed below with the maximum permissible gain and required
antenna impedance for each antenna type indicated. Antenna types not included in this list,
having a gain greater than the maximum gain indicated for that type, are strictly prohibited
for use with this device.
