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 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.
Explanation: The EUT has a PCB Antenna, and the antenna use a permanently
attached antenna which is not replaceable.
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: Yes, The module with trace antenna designs, and This manual has
been shown the layout
of trace design, antenna, connectors, and isolation requirements.
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: 2AGN8-WF862.
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 PCB Antenna, and the antenna use a permanently
attached antenna which is unique.
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: 2AGN8-WF862, Contains
IC: 20888-WF862”
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.
