Do wireless module reports cover my finished device?
No, not by themselves. Module reports may support your assessment, but they do not automatically establish the finished device's safety, electromagnetic compatibility or spectrum compliance. Match the evidence to the complete build and resolve gaps before release. Cambridge China Bridge can help coordinate factory evidence.
Separate module evidence from finished-device compliance
OPSS guidance says a finished product must comply with all applicable legislation when placed on the Great Britain market. The radio equipment requirements cover safety, electromagnetic compatibility and efficient spectrum use. Our practical conclusion is that a module report cannot establish those matters for the complete device without an assessment of its scope and integration.
Ask what the factory means by approved: a laboratory report, a declaration or a certificate? Identify the product each document covers. Use our wireless product guide for the wider compliance framework; this guide focuses on whether module evidence supports your finished build.
Match the reports to the installed module
Request complete reports, including photographs, results, appendices and installation conditions. Compare the tested module with the installed part: manufacturer, model, hardware revision, firmware, antenna, power supply and enabled radio settings. Ask the factory to explain every difference rather than accepting a similar model name.
Create a comparison sheet showing what was tested, what your device uses and what remains uncertain. Ask the laboratory or compliance adviser to explain which results can support the finished-device assessment and why. Our test report verification guide covers checking the documents themselves.
Assess the complete operating device
For safety, ask about the complete power and charging arrangement, battery, accessible parts, heat and intended use. For electromagnetic compatibility, include the host electronics, cables, enclosure and operating modes. For spectrum performance, ask how antenna installation, radio settings and simultaneous transmissions affect the assessment.
Give the assessor a complete working sample with its intended accessories and released firmware. Request a written gap assessment separating supported conclusions from further analysis or testing. Do not assume that every module test must be repeated, or that an unchanged module removes the need to assess its integration.
Agree who closes each evidence gap
OPSS says an importer must ensure that the manufacturer has carried out the relevant conformity assessment before placing radio equipment on the Great Britain market. Commissioning a laboratory review does not replace that check. Ask who owns the finished-device assessment and who will resolve each outstanding issue.
Make the deliverables specific: the assessed build, applicable standards and their scope, report references, unresolved issues and the reasoning supporting any reused module results. Keep this integration record with the technical compliance file. Avoid accepting a folder of module documents as the completed review.

Tie production approval to the assessed build
Record the approved module, antenna, enclosure, board layout, power components and firmware in the production specification. Require proposed substitutions to be submitted for review before use. Ask the assessor whether a proposed change affects existing evidence and what further work would resolve it.
Agree a release gate: outstanding assessment issues closed, evidence matched to the production sample and changes recorded. Cambridge China Bridge's staff in China can coordinate factory documents and sample identification; specialist assessment can be arranged through our testing and certification service.
Frequently asked questions
Can I use the factory's wireless module reports?
They may support the assessment. Ask an assessor to confirm that the tested module, installation conditions and report scope match your device, and identify what remains uncovered.
Does an unchanged module mean no finished-device testing?
Do not assume so. Have the complete integration reviewed, then agree which existing results are usable and which gaps need analysis or testing.
What sample should I send to the laboratory?
Send a complete working device with the intended antenna, enclosure, power supply, accessories and released firmware. Record its identity and differences from planned production.
Can the factory change the antenna after assessment?
Treat it as a proposed build change. Ask the assessor to review its effect on the existing evidence before approving the substitution.
