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.
Explanation: this module meets all the requirements of FCC part 2, 22(H),
24(E), 27(L), 27(F), 27(H),90(S)
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 no have permanently attached antenna , The test antenna gain is LTE B2/B25/B38/B41: 9.01 dBi, LTE B4/B66: 5.0dBi, LTE B5: 10.41dBi, LTE B7: 11.01dBi ,LTE B12: 8.69dBi,LTE B13: 10.15dBi,LTE B26: 10.35dBi,LTE B40: 0dBi,GSM 850:1.41dBi,GSM 1900:4.01dBi. The use condition of the prototype is mobile. Use conditions mainly for advertising machines, TV BOX and HDTV color..
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: this module is 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.
Explanation: No, this module without trance antenna designs.
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 module is designed to comply
with the FCC statement, feck id is:2AJYU-8BAE005
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 “omnidirectional 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: This module use External antenna. The test antenna gain is
LTE B2/B25/B38/B41: 9.01 dBi, LTE B4/B66: 5.0dBi, LTE B5: 10.41dBi, LTE B7:
11.01dBi ,LTE B12: 8.69dBi,LTE B13: 10.15dBi,LTE B26: 10.35dBi,LTE B40:
0dBi,GSM 850:1.41dBi,GSM 1900:4.01dBi.
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: On the metal shielding shell, there is space for printing basic
information such as the name and model of the product, and the id :2AJYU-
8BAE005 is included.
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: Data transfer module demo board can control the EUT work in
RF test mode at specified test channel.
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 do not require an evaluation by FCC part15 subpart B. The host
should be evaluated by the FCC subpart B.
