2.4GHz RF Modular Transceiver System
Installation manual (draft v1)
1. Description
This document describes an RF transceiver module PCB having two independent
radio transceivers. One radio complies to IEEE 802.11b/g protocols and the other to
the Bluetooth Low Energy specification. The module provided on-board power
regulation and full shielding for the radio transceivers.
2.
The module consists of 2 separate circuits :
1) A 2.4GHz Wi-Fi RF transceiver IC and two PIF etch antennas.
2) A 2.4GHz Bluetooth Low Energy transceiver IC and one PIF etch antennas.
3. Cautions:
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.
Any changes or modifications not expressly approved by Bose Corporation could void the
user's authority to operate this equipment.
WARNING! This module is to be installed only by Bose Corporation in its end products,
and shall not be marketed to any other party.
This RF Module has been certified for integration into products without further
certification. However, Bose Corporation is still responsible for testing its end products
for any additional compliance requirements required with this module installed (such as
digital device emissions, PC peripheral requirements, etc.).

End Product Labeling
This module is labeled with its own FCC ID and IC Certification Number. If the label is not visible
when the module is installed inside another device, then the outside of the device into which
this module is installed must also display a label referring to the enclosed module. In that case,
the final end product must be labeled in a visible area with the following:
“Contains Transmitter Module FCC ID: A94412568”
“Contains Transmitter Module IC: 3232A-412568”
or
“Contains FCC ID: A94412568”
“Contains IC: 3232A-412568”
IMPORTANT NOTE: In the event that these conditions can not be met (for certain
configurations or collocation with another transmitter), then the FCC and Industry
Canada authorizations are no longer considered valid and the FCC ID and IC
Certification Number can not be used on the final product. In that case the end
product must be re-evaluated to obtain separate FCC and Industry Canada
authorizations.
In addition, Information regarding how to install or remove this RF module or change its
RF related parameters should not be provided to the end user.
The user manual for the end product must include the following information in a
prominent location:
“To comply with FCC and Industry Canada RF radiation exposure limits for general
population/uncontrolled exposure, the antenna(s) used for this transmitter must be
installed such that a minimum separation distance of 20cm is maintained between the
radiator (antenna) and all persons at all times. In addition this transmitter must not be
collocated or operating in conjunction with any other antenna or transmitter.”
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.
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux
appareils radio exempts de licence. L'exploitation est autorisée aux deux conditions
suivantes : (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de
l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est
susceptible d'en compromettre le fonctionnement.
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.
Conformément à la réglementation d'Industrie Canada, le présent émetteur radio
peut fonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur)
Page 3
approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de
brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le type
d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente
(p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une communication
satisfaisante.
4. Markings
4.1 This module shall be identified with the following ID numbers on the radio
shields.
FCC ID : A94412568
IC : 3232A-412568
4.2 End Product Labeling
The final end product which this module is used in must be labeled in a visible
area with the following:
"Contains FCC ID: A94412568 / IC:3232A-412568"

7.2.3 Modulation: OFDM
7.2.4 Channel spacing: 5 MHz
7.3 Antenna Specification
The RF module uses three Planar Inverted F etch antennas, two in switched
diversity mode for Wi-Fi and one for Bluetooth Low Energy. The PCB layout
capture below shows their relative locations. The overall board dimensions are
225mm long by 37mm wide.
