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)
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 module has external antenna, BLE/BT has one ANT, WIFI has two
ANT,The antenna cannot be removed, Unconventional interface
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
