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 Part 15 Subpart C Section 15.249
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 uses PCB Antenna, antenna gain: 0dBi. There is no restriction on
the installation method.
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 mnodule
