RED: Radio Modules, Antennas and Connected-Product Changes
Module conformity alone does not establish every condition for the complete radio device. Antennas, housing, power and software settings require assessment together.
Questions for your situation
Is further work needed for a finished device using a CE-marked Wi-Fi module?
Compare approved antennas, supply and integration conditions with your design. Housing, cables and other circuits may affect radio performance, compatibility or safety. Reuse module evidence where justified and identify remaining assessments. Copying module information onto the label does not complete the final manufacturer's file.
Is increasing antenna gain only a decision about range?
Radiated behaviour, permitted operating conditions and exposure may change. Match antenna type, gain and connection to existing tests. Determine additional measurements and documentation. Fitting the same connector does not establish conformity equivalence between antennas.
Does enabling another frequency band through software change the file?
Check target-market bands and conditions, including how users can alter power, channels and region settings. The new mode may be absent from earlier tests. Align testing, instructions and necessary assessment outputs before releasing the update.
Do identical cybersecurity requirements apply to every RED device?
Compare connectivity, functions and processed information with the additional requirements' scope. Internet-connected, wearable and certain payment-enabled equipment may raise different questions. Assess CRA timing separately from applicable RED duties. One general security test should not imply coverage of every legal framework.
How should testing be planned when Bluetooth and Wi-Fi operate simultaneously?
Identify concurrent modes, antenna arrangements and challenging configurations. Separate module reports may not cover every combined effect. Review reusable evidence and additional measurements. Provide the laboratory with actual software modes and configurations supplied to users.
Is an old favourable report sufficient after an interference complaint?
Compare version, installation and operating mode with test conditions. Investigate manufacturing changes, settings and use. Base corrections, notifications and customer communication on actual risks. An earlier report does not remove investigation of a new problem in the real product.
Who is responsible when a ready-made radio module is incorporated into an own-brand product?
Determine the finished-product supplier's role under applicable law. The module file may not fully address antennas, power, software and integration in the final device. Arrange technical record access contractually and identify ownership of the finished-product file and declaration clearly.
Share the subject, organisation or product, target market, current evidence and target date. The team can then separate consultancy, official fees, independent evaluation and realistic timing.
