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),
