FCC Modular Usage Statement
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 (15.249).it specifically establish the
Conducted Emission, Radiated Spurious Emission, Field strength of fundamental, Band Edge Emission, 20dB
Bandwidth.
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 one PCB antenna, the antenna cannot be replaced by other authorized antennas.
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 a limited single module, Any modifications made to the module will void the
Grant of Certification, this module is limited to OEM installation only and must not be sold to end-users,
end-user shall have no manual instructions to remove or install the device, only software or operating
procedure shall be placed in the end-user operating manual of final products. shielded.
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, FCC ID is: 2AZ5M-RL61A1.
