Requirement per KDB996369 D03
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
Explanation: This module meets the requirements of FCC part 15C(15.247)& Part 15.407.
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.
Explanation: The EUT has a PIFA antenna, and the antenna used in the antenna is a replaceable
connection antenna.
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 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.
Explanation: The module is not a limited 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.
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.
Explanation: Not appliable.
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).
Explanation: This module complies with FCC RF radiation exposure limits set forth for an
uncontrolled environment, This equipment should be installed and operated with a
minimum distance of 20 centimeters between the radiator and your body." This module is
designed to comply with the FCC statement, FCC ID is: 2AAGEWBT56.
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.
Explanation: The EUT has a PIFA antenna, and the antenna used in the antenna is a
replaceable connection antenna.
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.
Explanation:The host system using this module, should have label in a visible area indicated
the following texts: “Contains FCC ID: 2AAGEWBT56, Contains IC: 11152A-WBT56”
2.9 Information on test modes and additional testing requirements5
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.
Explanation: Top band can increase the utility of our modular transmitters by providing
instructions that simulates or characterizes a connection by enabling a transmitter
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.
Explanation: The module without unintentional-radiator digital circuity, so the module does
not require an evaluation by FCC Part 15 Subpart B. The host shoule be evaluated by the FCC
Subpart B.
