WiFi Module
CDW.47W3155-00
Requirement per KDB996369 D03
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(15.247).it specifically establish the
6dB Bandwidth,, Peak Output Power, Radiated Spurious Emission, Power Spectral Density, Restricted
Band of Operation and Band Edge (Out of Band Emissions) &Measurement, This module meets the
requirements of FCC part 15E(15.407).it specifically establish the 6dB Bandwidth, 26 dB and 99%
Emission Bandwidth, Peak Output Power, Radiated Spurious Emission, Power Spectral Density,
Restricted Band of Operation and Band Edge (Out of Band Emissions) , Frequency Stability
Measurement
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 two external antenna, Antenna A support BT, Antenna B support
2.4GHz WIFI & 5GHz WIFI, Yes, the module have a permanently attached antenna, The antenna
gain is 2dBi.
2.4 Limited module procedures
If a modular transmitter is approved as a “limited module,” then the module manufacturer
isresponsible 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
