Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment.
This transmitter must not be co-located or operating in conjunction with any
other antenna or transmitter.
The availability of some specific channels and/or operational frequency bands
are country dependent and are firmware programmed at the factory to match the
intended destination.
The firmware setting is not accessible by the end user.
The final end product must be labeled in a visible area with the following:
“Contains Transmitter Module 2A3PA-ROCKPI4”
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).it specifically establish the 6dB Bandwidth,, Peak Output Power,
Radiated Spurious Emission, Power Spectral Density, Restricted Band of
Operation and Band Edge (Out of Band Emissions) Measurement
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.
Explanation: The EUT only has one Chip antenna, Yes, the module contains
a permanently attached antenna, and The antenna gain is 2dBi.
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 in which the
limited module is used. 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
with 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 a single 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: No, The module has no tracking antenna design, is a Chip
antenna.
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 2A3PA-ROCKPI4.
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 a unique antenna
connector must be used on Part 15 authorized transmitters used in the host
product. The module manufacturers shall provide a list of acceptable unique
connectors.
Explanation: The EUT only has one Chip antenna, Yes, the module contains
a permanently attached antenna, and The antenna gain is 2dBi.
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 a label in a
visible area indicating the following texts: “Contains FCC ID: 2A3PA-ROCKPI4
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 a label in a
visible area indicating the following texts: “Contains FCC ID: 2A3PA-ROCKPI4
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 simulate 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: WiFiRanger, A LinOra Company can increase the utility of our
modular transmitters by providing instructions that simulate 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 with 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 is without unintentional-radiator digital circuity, so
the module does not require an evaluation by FCC Part 15 Subpart B. The host
should be evaluated by the FCC Subpart B.
This product uses Chipantenna with a maximum antenna gain of 2dBi
