1. Purpose
The purpose of this document is to provide information on how to install the DBWIFIBLE01 module
into Dyson products.
The DBWIFIBLE01 module is only intended for integration into end host products by authorised
Dyson personnel. Incorrect integration or use may infringe compliance rules meaning recertification
may be required.
2. Module Overview
The Dyson DBWIFIBLE01 module is a standalone PCBA designed to provide WLAN and BLE
connectivity in a number of Dyson products. It supports dual-band 1 × 1 IEEE802.11a/b/g/n WLAN
and BLE operation. It is based on a reference design from Qualcomm based on their QCA4020 Dual
Band Wi-Fi + Bluetooth Chipset.
From this point forward in the document the DBWIFIBLE01 module will simply be referred to as the
‘module’.
The module incorporates the QCA4020 chipset, external Flash, RF front end and an integrated PCB
solution for each of the three frequency bands supported. The design is realised on a single PCB with
all RF and clock devices screened by a metal shielding can. The Module requires a 3.3V input power
supply.

2.1. Antenna(s)
The module has two distinct antennas. Both antennas are printed on the PCB carrier board. The 4
layer PCB substrate is FR4 with a nominal Er of 4.2. The antenna are realised on the top (layer1) and
bottom (layer4) of the PCB.
Antenna A is a Dual Band WLAN antenna covering the 2400MHz to 2483.5MHz Band and the
5.170 to 5.835MHz band.
Antenna B is a BLE antenna covering the 2400MHz to 2483.5MHz Band.
3. Integration Into Host Products
Module System Controller Connecter
1. Modules are supplied with a connector that
is used to connect to the host product
system controller interface. The host system
controller will be design to operate the
module and set the respective RF
parameters.
Host Product Connector/Cable to Module
2. The host product must be designed to
provide connection two the module.

3. The host product system controller cable is
inserted in to the module connector.
4. The host product must be designed to
securely hold the module in place. In this
example a vertical slotted stand is used.
Once the module is securely in place final of
the host product can be completed.

4. Module Label
5. Host Product Labelling
A label is to be fitted to the exterior of all products containing the DBWIFIBLE01 module. The label
must contain the words “Contains FCC ID: QVHDBWIFIBLE01” (for FCC) and “Contains IC: 7986A-
DBWIFIBLE01”

6. Compliance Statements
6.1. FCC
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions:
1) The device may not cause harmful interference, and
2) The device Module must accept any interference received, including interference that
may cause undesired operation.
This device complies with FCC RF radiation exposure limits set forth for an uncontrolled
environment. The antenna used for this transmitter must be installed to provide a separation
distance of at least 20 cm for mobile applications and 10 cm for portable applications from all
persons and must not be co-located or operating in conjunction with any other antenna or
transmitter.
Important Note: 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.
This transmitter must not be co-located or operating in conjunction with any other antennas or
transmitters.
It is the responsibility of the host device manufacturer to ensure continued compliance with FCC rule
part 15B once the module has been installed in the host device.
Changes or modifications not expressly approved by the party responsible for compliance could void
the user's authority to operate the equipment.
The concerned end product must be labelled to say: “Contains FCC ID: DBWIFIBLE01”

6.2. ISED
6.2.1. English
This device complies with Innovation, Science and Economic Development Canada (ISED) licence-
exempt RSS standard(s). Operation is subject to the following two conditions:
1) The device may not cause interference, and
2) The device must accept any interference, including interference that may cause undesired
operation of the device.
Important note: To comply with Industry Canada RF exposure limits, the antenna used for this device
must be installed to provide a separation distance of at least 20cm from all persons.
RF exposure is in accordance with RSS-102, section 2.5.2.
The concerned end product must be labelled to say: “Contains IC: 7986A-WIFIAMFA001”
6.2.2. French
Cet equipement est conforme aux normes d’exemption de licence RSS Innovation, Sciences et
Développement économique Canada. Son utilisation est soumise aux deux conditions suivantes:
1) Le dispositif ne doit pas provoquer d’interference, et
2) Le dispositif doit accepter toute interference, y compris des interferences susceptibles de
provoquer un fonctionnement indesirable de l’equipement.
Remarque importante: Pour respecter les limites d’exposition aux radiofrequences Innovation,
Sciences et Développement économique Canada, l'antenne utilisee pour cet appareil doit etre
installe pour fournir une distance de separation d'au moins 20 cm de toutes les personnes.
L'exposition aux RF est conforme a la norme RSS-102, section 2.5.2.
Le produit final concerne doit porter une etiquette avec la mention: "Contient IC: 7986A-
