Meaning
Equipment authorization grants defined by regulatory agencies specify exact operating conditions, antenna gains and physical configurations under which pre-certified radio modules may be integrated without full system re-testing. Host product manufacturers evaluate a modular radio grant scope to determine if intended product designs require permissive change filings or complete system authorization. Grant conditions stop applying when host devices introduce collocated transmitters or alter certified trace layouts.
Integration Boundary
Host system boards must adhere to trace layout designs and power supply decoupling specifications defined in module integration manuals. Deviation from tested microstrip geometry invalidates existing regulatory test reports. Third-party antenna substitution requires verification that gain parameters stay within original grant limits.
Permissive Change
Adding a certified module to a host that operates within twenty centimeters of the human body triggers mandatory RF exposure evaluation. Simultaneous transmission with cellular or wireless local area network radios alters compliance obligations. Exceeding the original modular radio grant scope forces full intentional radiator testing on completed host assemblies.
Documentation records must archive original module filings alongside host integration verification logs.
Compliance Documentation
Labeling requirements dictate that host product exteriors display module regulatory identifier codes. User manuals must contain mandatory regulatory warning statements regarding antenna spacing and operational limits. OEM agreements bind host builders to compliance restrictions set forth in initial grants.
