Specifications

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)/RSS-247.
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 a PCB Antenna , and the antenna use a permanently attached antenna which is
not replaceable.
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 not 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.
