1. Contention-Based Protocol, as demonstrated in the FCC test report, is permanently embedded in the module and is
not host-dependent, can’t change by anyone.
2. Operation of transmitters in the 5.25-5.35GHz, 5.47-5.725GHz, 5.85-5.895GHz, 5.925-7.125GHz bands is this
Modular device will only associate and connect with a low-power indoor access point or subordinate device and never
directly connect to other client devices.
This feature is include in its firmware and can’t change by anyone.
3. Operation of transmitters in the 5.25-5.35GHz, 5.47-5.725GHz, 5.85-5.895GHz, 5.925-7.125GHz bands is this
Modular device will always initiate transmission under the control of a low-power indoor AP or subordinate except for
brief transmissions before joining a network. These short messages will only occur if the client has detected an indoor
AP or subordinate operating on a channel. These brief messages will have a time-out mechanism such that if it does
not receive a response from an AP it will not continually repeat the request.
4. That transmissions will be lower or equal to the power advertised by the indoor low-power access point or
subordinate and never above the maximum output power allowed by the FCC grant for equipment class 6XD.
This device complies with Part 15 of the FCC`s 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 undesirable operation.
To satisfy FCC exterior labeling requirements, the following text must be placed on the exterior of the end product.
Contains Transmitter module FCC ID: A3LWCC940M
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 or more 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.
-The OEM integrator is responsible for ensuring the end-user has no manual instruction to remove or install module.
-The module is limited to installation in mobile or fixed applications.

Version 1.0 page 4 of 9
This module is intended for OEM integrators only. Per FCC KDB 996369 D03 OEM Manual v01
guidance, the following conditions must be strictly followed when using this certified module:
KDB 996369 D03 OEM Manual v01 rule sections:
2.2 List of applicable FCC rules
This module has been tested for compliance to FCC Part 15 Subpart C (15.247) and Subpart E (15.407).
2.3 Summarize the specific operational use conditions
The module is tested for standalone mobile RF exposure use condition. Any other usage conditions such as co-
location with other transmitter(s) will need a separate reassessment through a class II permissive change
application or new certification.
This module is authorized for Low Power Indoor Client applications only; final host product must be for indoor
operations only.
Further operation restrictions on the host product include:
*Prohibited for control of or Communications with unmanned aircraft systems.
2.4 Limited module procedures
Not applicable.
2.5 Trace antenna designs
Not applicable.
2.6 RF exposure considerations
This equipment complies with FCC mobile radiation exposure limits set forth for an uncontrolled environment.
This equipment should be installed and operated with a minimum distance of 20cm between the radiator & your
body. A separate SAR/Power Density evaluation is required to confirm compliance with relevant FCC portable
RF exposure rules.
2.7 Antennas
The following antennas have been certified for use with this module; antennas of the same type with equal or
lower gain may also be used with this module except for operations within the 5.925~7.125GHz band.
Use of other antenna types or the same type of antenna with higher gain than listed above must performed
additional testing and appropriate permissive change approval.
Note2: In the 5.925-7.125GHz band, use of other similar type antennas and the antenna gain not higher/lower
than listed above may only require a C1PC without any additional testing/submission.
Note3: Additional testing/submission (C2PC) will required if device not met the antenna and RF exposure
requirements.
Note4: Contact Samsung for additional guidance, if choose to use different antenna types or higher/lower gain
antennas in the end system.

transmission with other transmitter(s) class II permissive change re-evaluation or new certification.
2.10 Additional testing, Part 15 Subpart B disclaimer
This transmitter module is tested as a subsystem and its certification does not cover the FCC Part 15 Subpart B
(unintentional radiator) rule requirement applicable to the final host. The final host will still need to be
reassessed for compliance to this portion of rule requirements if applicable.
As long as all conditions above are 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.
IMPORTANT NOTE: In the event that these conditions can not be met (for example certain laptop
configurations or co-location 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 re-evaluating the end product (including the transmitter) and obtaining a separate FCC
authorization.
Manual Information To the End User
The OEM integrator has to be aware not to provide information to the end user regarding how to install or
remove this RF module in the user’s manual of the end product which integrates this module.
The end user manual shall include all required regulatory information/warning as show in this manual.

OEM/Host manufacturer responsibilities
OEM/Host manufacturers are ultimately responsible for the compliance of the Host and Module.
The final product must be reassessed against all the essential requirements of the FCC rule such as FCC Part
15 Subpart B before it can be placed on the US market. This includes reassessing the transmitter module for
compliance with the Radio and EMF essential
requirements of the FCC rules. This module must not be incorporated into any other device or system without
retesting for compliance as multi-radio and combined equipment.
Modules: extended to host manufacturers by integration instructions.
IMPORTANT NOTE
This device complies with FCC & IC radiation exposure limits set forth for an uncontrolled environment. This
device should be installed and must not be co-located or operating in conjunction with any other antenna or
transmitter.
This device is intended only for OEM integrators under the following conditions:
1) This module may not be co-located with any other transmitters or antennas.
2) The antenna must be installed such that 20cm is maintained between the antenna and users.
As long as 2 conditions above are 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 with this module
installed. In the event that these conditions cannot be met, then the FCC & IC authorizations are no longer
considered valid and the FCC ID cannot be used on the final product. In these circumstances, the OEM
integrator will be responsible for re-evaluating the end product including this module and obtaining separate FCC
& IC authorizations.
