Broadcom BRCM1055 Users Manual

OEM Installation Guidance Document

For BRCM WLAN Module, BCM94331PCIEBT4

FCC ID: QDS-BRCM1055; IC: 4324A-BRCM1055

Conditions on using BRCM regulatory approvals:

A. Customer must ensure that its product (the “CUSTOMER Product”) is electrically
identical to Broadcom’s reference designs. Customer acknowledges that any
modifications to Broadcom’s reference designs may invalidate regulatory approvals in
relation to the CUSTOMER Product, or may necessitate notifications to the relevant
regulatory authorities.

B. Customer is responsible for ensuring that antennas used with the product are of
the same type, with same or lower gains as approved and providing antenna reports to
Broadcom.

C. Customer is responsible for regression testing to accommodate changes to
Broadcom’s reference designs, new antennas, and portable RF exposure safety
testing/approvals.

D. Appropriate labels must be affixed to the CUSTOMER Product that comply with
applicable regulations in all respects.

E. A user’s manual or instruction manual must be included with the customer
product that contains the text as required by applicable law. Without limitation of the
foregoing, an example (for illustration purposes only) of possible text to include is set
forth below:

1. USA—Federal Communications Commission (FCC)

FCC COMPLIANCE STATEMENT:

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.

INFORMATION TO USER:

This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of 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. If not installed and used in
accordance with the instructions, it 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 tuning the equipment off and on, the

user is encouraged to try and correct the interference by one or more of the following
measures:

-Reorient or relocate the receiving antenna

-Increase the distance between the equipment and the receiver.

-Connect the equipment to 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: Any changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to operate this equipment.

CAUTION: (this only applicable to 5GHz device)
This device is restricted to indoor use due to its operation in the 5.15 to 5.25 GHz
frequency range. FCC requires this product to be used indoors for frequency range 5.15
to 5.25 GHz to reduce the potential for harmful interference to co-channel Mobile
Satellite systems.
High power radars are allocated as primary users of the 5.25 to 5.35 GHz and 5.65 to

5.85 GHz bands. These radar stations can cause interference with and/or damage this
device.

System integrators must include the FCC ID on the end product.

FCC Radio-Frequency Exposure & Approval Conditions:

1. Antennas must be installed in the display section of Netbook/notebook/laptop
computer to provide at least XXcm separation distance from the transmitting antenna to
the body of user during normal operating condition.

2. Transmitting antenna(s) can only be installed at the display section of computer. When
this device is installed other than notebook computers, at least 20 cm separation distance
shall be maintained between the transmitting antenna(s) to the body of user or nearby
person.

3. The antenna(s) used for this transmitter must not be collocated or operating in
conjunction with any other antenna or transmitter within a host device, except in
accordance with FCC multi-transmitter product procedures.

4. Only those antennas with same type and lesser gain filed under this FCC ID number
can be used with this device.

5. The regulatory label on the final system must include the statement: “Contains FCC
ID: QDS-BRCM1055 and/or IC: 4324A-BRCM1055” or using electronic labeling
method as documented in KDB 784748.

6. The final system integrator must ensure there is no instruction provided in the user
manual or customer documentation indicating how to install or remove the transmitter

module except such device has implemented two-ways authentication between module
and the host system.

7. The final host manual shall include the following regulatory statement:
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of 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. If not installed and used in
accordance with the instructions, it 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 tuning the equipment off and on, the
user is encouraged to try and correct the interference by one or more of the following
measures:

-Reorient or relocate the receiving antenna

-Increase the distance between the equipment and the receiver.

-Connect the equipment to 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.

2. Canada - Industry Canada (IC)

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 this device.”
L ‘ utilisation de ce dispositif est autorisée seulement aux conditions suivantes : (1) il ne
doit pas produire de brouillage et (2) l’ utilisateur du dispositif doit étre prêt à accepter
tout brouillage radioélectrique reçu, même si ce brouillage est susceptible de
compromettre le fonctionnement du dispositif.

To reduce potential radio interference to other users, the antenna type and its gain should
be so chosen that the equivalent isotropically radiated power (EIRP) is not more than that
required for successful communication.

This device has been designed to operate with a 802.11abgn antenna, having a maximum
gain of 5.65dBi/2.4GHz and 7.25dBi/5GHz. Different types of antennas or the same type
of antenna having a gain greater than 5.65dBi/2.4GHz and 7.25dBi/5GHz are strictly
prohibited for use with this device. The required antenna impedance is 50ohms.
