Meaning
Regulatory guidance documents published by the Federal Communications Commission outline the compliance requirements and testing procedures for products that integrate pre-certified transmitter modules. This publication ensures that host devices do not introduce unauthorized emissions when incorporating modular wireless solutions. Manufacturers must adhere to these directives to maintain the validity of the modular certification on their final products.
Compliance Procedure
Industrial integration of pre-certified wireless components requires adherence to specific testing and documentation rules. Under FCC KDB 996369, the host product manufacturer is responsible for performing exploratory measurements to verify that the integrated module continues to comply with the technical limits. Initial measurements must be completed before the final product can be legally sold in the United States, as any deviation from the modular integration guidelines can result in enforcement action.
Modular Approval
Module reuse in new product designs reduces certification costs but requires careful verification of host-specific layouts. The guidelines in FCC KDB 996369 define the boundaries of modular approval, including rules for antenna trace designs and host-specific shielding configurations. A failure to follow these trace layouts invalidates the existing modular grant and triggers a full certification process.
Testing Strategy
Multi-transmitter testing protocols must be designed to evaluate intermodulation products and simultaneous transmission scenarios. Applying FCC KDB 996369 helps test laboratories configure the host system during evaluation to ensure that all internal radios are active during emissions sweeps. This structured test strategy ensures that the combined system complies with all unwanted emission requirements.
