Wi-Fi&Bluetooth Module Series
Explanation: This module has been granted Single Modular Approval for mobile applications.
OEM
integrators for host products may use the module in their final products without additional
FCC certifications if they meet the following conditions. Otherwise, additional FCC
approvals must be obtained. The host product with the module installed must be evaluated for
simultaneoustransmission requirements The user's manual for the host product must clearly
indicate the operating requirements and conditions that must be observed to ensure compliance
with current FCC RF exposure guidelines. To comply with FCC regulations limiting both
maximum RF ourput power and human exposure to RF radiation. A label must be affixed to the
outside of the host product product with the following statement: This device contains FCC ID:
YQD-QLM100 The final host/Module combinations may also need to be evaluated against the FCC
Part 15B criteria for unintentional radiators in order to be properly authorizaed for operation as
a Part 15 digital device.
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;
