Navigating Modular Approvals and Host Integrator Responsibilities
Modular radio approvals cover baseline intentional radiation but transfer host level unintentional emissions, SAR exposure, and final assembly compliance to the integrator.
Host Integrator
Meaning
Entity that incorporates a pre-certified radio module into an end-product and assumes responsibility for the final compliance of the combined system. The host integrator must follow the module manufacturer’s installation instructions exactly to maintain the validity of the original grant. Any deviation requires new testing and certification.
Certification Transfer
Modules are often certified for use with specific antennas and at certain distances from the human body. When a host integrator stays within these parameters, they can leverage the existing FCC or CE reports to simplify their own filing. This significantly reduces the time and cost required to bring a new product to market.
Interface Specification
Proper operation of the module depends on the quality of the power and data lines provided by the host mainboard. The host integrator ensures that voltage ripples are kept low and that high-speed data traces are correctly shielded. Poor integration can lead to radio performance issues even with a certified module.
Final Verification
Even when using pre-approved parts, the complete device must undergo unintentional radiator testing to check for noise from the enclosure and cabling. A host integrator performs these tests to ensure the product does not interfere with other electronics. This check is a mandatory part of the manufacturing quality process.
