2.2 List of applicable FCC rules
List the FCC rules that are applicable to the modular transmitter. These
are the rules that specifically establish the bands of operation, the power,
spurious emissions, and operating fundamental frequencies. DO NOT list
compliance to unintentional-radiator rules (Part 15 Subpart B) since that is
not a condition of a module grant that is extended to a host manufacturer. See
also Section 2.10 below concerning the need to notify host manufacturers that
further testing is required.3| YES| | Refer to instruction
FCC standards: FCC CFR Title 47 Part 15 Subpart C Section 15.247
2.3 Summarize the specific operational use conditions
Describe use conditions that are applicable to the modular transmitter,
including for example any limits on antennas, etc. For example, if point-to-
point antennas are used that require reduction in power or compensation for
cable loss, then this information must be in the instructions. If the use
condition limitations extend to professional users, then instructions must
state that this information also extends to the host manufacturer’s
instruction manual. In addition, certain information may also be needed, such
as peak gain per frequency band and minimum gain, specifically for master
devices in 5 GHz DFS bands.| YES| | Refer to instruction
The module is limited to the following antenna:
Antenna Type: PCB Antenna Antenna Gain: -1dBi
2.4 Limited module procedures
If a modular transmitter is approved as a “limited module,” then the module
manufacturer is responsible for approving the host environment that the
limited module is used with. The manufacturer of a limited module must
describe, both in the filing and in the installation instructions, the
alternative means that the limited module manufacturer uses to verify that the
host meets the necessary requirements to satisfy the module limiting
conditions. A limited module manufacturer has the flexibility to define its
alternative method to address the conditions that limit the initial approval,
such as: shielding, minimum| No| |
signaling amplitude, buffered modulation/data inputs, or power supply
regulation. The alternative method could include that the limited module
manufacturer reviews detailed test data or host designs prior to giving the
host manufacturer approval.
This limited module procedure is also applicable for RF exposure
evaluation when it is necessary to demonstrate compliance in a specific host.
The module manufacturer must state how control of the product into which the
modular transmitter will be installed will be maintained such that full
compliance of the product is always ensured. For additional hosts other than
the specific host originally granted with a limited module, a Class II
permissive change is required on the module grant to register the additional
host as a specific host also approved with the module.| **| |
2.5 Trace antenna designs
For a modular transmitter with trace antenna designs, see the guidance in
Question 11 of KDB Publication 996369 D02 FAQ – Modules for Micro-Strip
Antennas and traces. The integration information shall include for the TCB
review the integration instructions for the following aspects: layout of trace
design, parts list (BOM), antenna, connectors, and isolation requirements. 4
a) Information that includes permitted variances (e.g., trace
boundary limits, thickness, length, width, shape(s), dielectric constant, and
impedance as applicable for each type of antenna);
b) Each design shall be considered a different type (e.g., antenna
length in multiple(s) of frequency, the wavelength, and antenna shape (traces
in phase) can affect antenna gain and must be considered);
c) The parameters shall be provided in a manner permitting host
manufacturers to design the printed circuit (PC) board layout;
d) Appropriate parts by manufacturer and specifications;
e) Test procedures for design verification; and
f) Production test procedures for ensuring compliance.
The module grantee shall provide a notice that any deviation(s) from the
defined parameters of the antenna trace, as described by the instructions,
require that the host product manufacturer must notify the module grantee that
they wish to change the antenna trace design. In this case, a Class II
permissive change application is required to be filed by the grantee, or the
host manufacturer can take responsibility through the change in FCC ID (new
application) procedure followed by a Class II permissive change
application.| No| |

2.6 RF exposure considerations
It is essential for module grantees to clearly and explicitly state the
RF exposure conditions that permit a host product manufacturer to use the
module. Two types of instructions are required for RF exposure information:
(1) to the host product manufacturer, to define the application conditions
(mobile, portable – xx cm from a person’s body); and (2) additional text
needed for the host product manufacturer to provide to end users in their end-
product manuals. If RF exposure statements and use conditions are not
provided, then the host product manufacturer is required to take
responsibility of the module through a change in FCC ID (new
application).| YES| | Refer to instruction
The modular can be installed or integrated in mobile or fix devices only. This
modular cannot be installed in any portable device. This modular complies with
FCC RF radiation exposure limits set forth for an uncontrolled environment.
This transmitter must not be co-located oroperating in conjunction with any
other antenna or transmitter. This modular must be installed and operated with
a minimum distance of 20 cm between the radiator and user body.
2.7 Antennas
A list of antennas included in the application for certification must be
provided in the instructions. For modular transmitters approved as limited
modules, all applicable professional installer instructions must be included
as part of the information to the host product manufacturer. The antenna list
shall also identify the antenna types (monopole,
PIFA, dipole, etc. (note that for example an “omni-directional
antenna” is not considered to be a specific “antenna type”)).
For situations where the host product manufacturer is responsible for an
external connector, for example with an RF pin and antenna trace design,
the integration instructions shall inform the installer that unique
antenna connector must be used on the Part 15 authorized transmitters used in
the host product. The module manufacturers shall provide a list of
acceptable unique connectors.| YES| | Refer to instruction
The module is limited to the following antenna:
Antenna Type: PCB Antenna Antenna Gain: -1dBi
2.8 Label and compliance information Grantees are responsible for the
continued compliance of their modules to the FCC rules. This includes advising
host product manufacturers that they need to provide a physical or e-label
stating “Contains FCC ID” with their finished product. See Guidelines for
Labeling and User Information for RF Devices – KDB Publication 784748.|
YES| | Refer to instruction
If the FCC identification number is not visible when the module is installed
inside another device, then the outside ofthe device into which the module is
installed must also display a label referring to the enclosed module.
Thisexterior label can use wording such as the following: “Contains
Transmitter Module FCC ID: 2AQ95-C22K Or Contains FCC ID: 2AQ95- C22K ”
2.9 Information on test modes and additional testing requirements 5
Additional guidance for testing host products is given in KDB Publication
996369 D04 Module Integration Guide. Test modes should take into consideration
different operational conditions for a stand-alone modular transmitter in a
host, as well as for multiple simultaneously transmitting modules or other
transmitters in a host product.
The grantee should provide information on how to configure test modes for
host product evaluation for different operational conditions for a stand-alone
modular transmitter in a host, versus with multiple, simultaneously
transmitting modules or other transmitters in a host.
Grantees can increase the utility of their modular transmitters by
providing special means, modes, or instructions that simulates or
characterizes a connection by enabling a transmitter. This can greatly
simplify a host manufacturer’s determination that a module as installed in
a host complies with FCC requirements.| YES| | Refer to instruction
Any company of the host device which install this modular with limit modular
approval should perform the test ofradiated & conducted emission and spurious
emission,etc. according to FCC part 15C: 15.247 and 15.209 &15.207, 15B
Class B requirement, Only if the test result comply with FCC part 15C: 15.247
and 15.209 &15.207, 15B Class B requirement，then the host can be sold legally.
The module is installed in the host and can be transmitted independently.
2.10 Additional testing, Part 15 Subpart B disclaimer
The grantee should include a statement that the modular transmitter is
only FCC authorized for the specific rule parts (i.e., FCC transmitter
rules) listed on the grant, and that the host product manufacturer is
responsible for compliance to any other FCC rules that apply to the host not
covered by the modular transmitter grant of certification. If the grantee
markets their product as being Part 15 Subpart B compliant (when it also
contains unintentional-radiator digital circuity), then the grantee shall
provide a notice stating that the final host product still requires Part 15
Subpart B compliance testing with the modular transmitter installed.6|
Yes| | Refer to instruction
The module is installed in the host, and the host must be evaluated to comply
with Part 15 Subpart B requirements
