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. Seal so Section 2.10 below concerning the need to notify host manufacturers that further testing isrequired.3
Explanation: This module meets the requirements of FCC part 15C(15.247).it Specifically identified AC Power Line Conducted Emission, Radiated Spurious emissions, Band edge and RF Conducted Spurious Emissions, Conducted Peak Output Power, Bandwidth, Power Spectral Density ,Antenna Requirement.

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, 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 instruction manual. In addition, certain information may also be needed, such as peak gain per frequency band and minimum gain, specifically for master devicesor 5 GHz DFS bands.
• Explanation: The antenna can’t be replaced by other authorized antennas, and the gain of each replacement antenna is no more than 2.57dBi, This module is limited used antenna as below:

Limited module procedures
In accordance with 47CFR 15.212 Modular Transmitters and KDB 996369 D01 * Module Equip Auth Guide v02′. FCC ID 2BDDW-BLM8723DS1 cannot meet the integrated antenna and do not contain power supply regulation on the module.

• If a modular transmitter is approved as a “limited module,” then the module manufacturer isresponsible for approving the host environment that thelimitedmodule is used with. The manufacturer of a limited module mustdescribe,both in the filing and in the installation instructions, the alternative meansthatthe limited module manufacturer uses to verify that the host meetsthenecessary requirements to satisfy the module limitingconditions. A limited module manufacturer has the flexibility to define itsalternativemethod
  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 a limited single module. the module without antenna and the module was not tested in stand-alone configuration – it was tested in the Host.

Trace antenna designs

• If trace antenna designs are applicable, full-detail design specifications are required per D02 Module Q&A Question 11.
• 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.4
  •  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);
  • 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);
  •  The parameters shall be provided in a manner permitting host manufacturers to design the printed circuit (PC) board layout;
  • Appropriate parts by manufacturer and specifications;
  •  Test procedures for design verification; and
  • Production test procedures for ensuring compliance.
• The module grantee shall provide a notice that any deviation(s) from the defined parameters of the antenna trace, as described by the instructions, require that the host product manufacturer must notify the module grantee that they wish to change the antenna trace design. In this case, a Class II permissive change application is required to be filed by the grantee, or the host manufacturer can take responsibility through the change in FCC ID (new application) procedure followed by a Class II permissive change application.

Explanation: not applicable

RF exposure considerations
It is essential for module grantees to clearly and explicitly state the RFexposure 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 20cm between the radiator and your body. “This module is designed to comply with the FCC statement, FCC ID is:2BDDW- BLM8723DS1.

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: This module is limited used antenna as below: 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 –KDBPublication784748.
• Explanation: The host system using this module, should have label in a visible area indicated the following texts: “Contains FCC ID: 2BDDWBLM8723DS1.

Information on test modes and additional
testing requirements5 Additional guidance for testing host products is given in KDBPublication996369 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 astand-alonemodular transmitter in a host, versus with multiple, simultaneouslytransmittingmodules or other transmitters in ahost.
• Grantees can increase the utility of their modular transmitters by providing special means, modes, or instructions that simulates or characterizes 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: Hangzhou Sound live Electronic Co.,Ltd. can increase the utility of our modular transmitters by providing instructions that simulates or characterizes a connection by enabling transmitter.

Additional testing, Part 15 Sub part B disclaimer
The grantee should include a statement that the modular transmitter is only FCC authorized for the specific rule parts (i.e., FCC transmitter rules) listed on the grant, and that the host product manufacturer is responsible for compliance to any other FCC rules that apply to the host not covered by the modular transmitter grant of certification. If the grantee markets their product as being Part15 Subpart B compliant (when it also contains unintentional-radiator digital circuity), then the grantee shall provide a notice stating that the final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed.
Explanation: The module without unintentional-radiator digital circuity, so the module does not require an evaluation by FCC Part 15 Subpart B. The host should be evaluated by the FCC Subpart B.

OEM integration instructions

• This device is intended only for OEM integrators under the following conditions:
  • The transmitter module may not be co-located with any other transmitter or antenna. The module shall be only used with the external antenna(s) that has been originally tested and certified with this module.
  • As long as the conditions above are met, further transmitter test will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed (for example ,digital device emissions, PC peripheral requirements ,etc.).
• Validity of using the module certification:
  • In the event that these conditions cannot be met (for example certain laptop configurations or co-location with another transmitter), then the FCC authorization for this module in combination with the host equipment is no longer considered valid and the FCC ID of the module cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization.
• End product labeling:
  • The final end product must be labeled in a visible area with the following: “Contains Transmitter Module FCC ID:2BDDW-BLM8723DS1”. Information that must be placed in the end user manual:
  • The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module in the user’s manual of the end product which integrates this module. The end user manual shall include all required regulatory information/warning as show in this manual.
