1.4 RF exposure considerations
It is essential for module grantees to clearly and explicitly state the RF exposure conditions that permit a
host product manufacturer to use the module. Two types of instructions are required for RF exposure
information: (1) to the host product manufacturer, to define the application conditions (mobile, portable –
xx cm from a person’s body); and (2) additional text needed for the host product manufacturer to provide
to end users in their end-product manuals. If RF exposure statements and use conditions are not
provided, then the host product manufacturer is required to take responsibility of the module through a
change in FCC ID (new application).
Explanation: This module complies with FCC RF radiation exposure limits set forth for an uncontrolled
environment, This equipment should be installed and operated with a minimum distance of 20
centimeters between the radiator and your body." This module is designed to comply with the FCC
statement, FCC ID is: 2AOKI-WFM63BUSX3
1.5 Antennas
A list of antennas included in the application for certification must be provided in the instructions. For
modular transmitters approved as limited modules, all applicable professional installer instructions must
be included as part of the information to the host product manufacturer. The antenna list shall also
identify the antenna types (monopole, PIFA, dipole, etc. (note that for example an
“omni-directional antenna” is not considered to be a specific “antenna type”)).
For situations where the host product manufacturer is responsible for an external connector, for
example with an RF pin and antenna trace design, the integration instructions shall inform the installer
that unique antenna connector must be used on the Part 15 authorized transmitters used in the host
product. The module manufacturers shall provide a list of acceptable unique connectors.
Explanation: The EUT has a FPC Antenna, , and the antenna use a permanently attached antenna
which is unique.
1.6 Label and compliance information
Grantees are responsible for the continued compliance of their modules to the FCC rules. This
includes advising host product manufacturers that they need to provide a physical or e-label stating
“Contains FCC ID” with their finished product. See Guidelines for Labeling and User Information for
RF Devices – KDB Publication 784748.
Explanation:The host system using this module, should have label in a visible area indicated the
following texts: "Contains FCC ID: 2AOKI-WFM63BUSX3
1.7 Information on test modes and additional testing requirements5
Additional guidance for testing host products is given in KDB Publication 996369 D04 Module Integration
Guide. Test modes should take into consideration different operational conditions for a stand-alone
modular transmitter in a host, as well as for multiple simultaneously transmitting modules or other
transmitters in a host product.
The grantee should provide information on how to configure test modes for host product evaluation for
different operational conditions for a stand-alone modular transmitter in a host, versus with multiple,
simultaneously transmitting modules or other transmitters in a host.
Grantees can increase the utility of their modular transmitters by providing special means, modes, or
instructions that simulates or characterizes a connection by enabling a transmitter. This can greatly
simplify a host manufacturer’s determination that a module as installed in a host complies with FCC
requirements.
Explanation: Topband can increase the utility of our modular transmitters by providing instructions that
simulates or characterizes a connection by enabling a transmitter.
