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 15 -247&FCC Part 15, Subpart E (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 no have permanently atached antenna , The test antenna gain is 2.4G: 3.46 dBi,
5G: 3.37dBi. The use condition of the prototype is mobile . Use conditions mainly for advertising machines
and HDTV colar .

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
