Integrating radio modules into a host product

As connected technology continues to advance, radio modules are becoming a fundamental component in a growing number of products across industries. Whether embedded in consumer electronics, industrial systems, medical devices, or smart infrastructure, radio technologies introduce a unique set of regulatory and technical considerations that manufacturers must understand early in the design and development process.

Ensuring compliance is not simply a matter of running tests - it requires a clear understanding of approval pathways, regional regulations, and how a radio module behaves once integrated into a host device.

This whitepaper, authored by regulatory compliance specialist Alex Toohie, provides a structured and accessible introduction to this complex landscape. It explains the compliance journey in practical terms, guiding manufacturers through the decisions and responsibilities that shape a product’s route to market. By exploring the interplay between module performance, host product design, and global regulatory frameworks, the guide helps engineering and compliance teams avoid common pitfalls, minimise delays, and make informed decisions from the outset.

Why download this whitepaper?

Understand the difference between testing and approvals—a foundational concept that influences cost, timelines, and overall compliance strategy.
Learn the three‑step compliance process for radio‑enabled products, from determining required approvals to selecting appropriate testing and completing documentation.
Gain clarity on major global regulatory schemes such as CE, UKCA/UKNI, FCC, and ISED, and understand how each treats radio performance, EMC, safety, and RF exposure.
Explore how risk assessments guide the compliance journey, informing testing decisions and reducing the likelihood of late‑stage failures.
Deepen your knowledge of key technical areas, including EMC behaviour, safety assessments, RF exposure evaluations, radio spectrum usage, and emerging cyber security requirements.
Understand the complexities of modular approvals, what they do—and do not—cover, and the responsibilities that remain with the host integrator.
Learn how multi‑radio coexistence impacts compliance, including intermodulation risks, simultaneous transmission scenarios, and necessary testing approaches.
Identify integration pitfalls that can lead to re‑testing or invalidated certifications, helping teams plan proactively and avoid expensive redesigns.
Equip product designers with early‑stage guidance to improve performance, reduce risk, and streamline the path to market.

Radio Module Integration Guide: Abstract

The Radio Module Integration Guide offers a clear and comprehensive overview of the regulatory and technical factors involved in integrating radio modules into host products for international markets. It explains the crucial differences between testing and approvals and outlines a three‑step process: identifying required certifications based on geography and radio technology, determining the appropriate testing strategy, and preparing and maintaining the necessary compliance documentation. The whitepaper introduces the core features of global regulatory frameworks—including CE, UKCA/UKNI, FCC, and ISED—showing how each addresses essential areas such as EMC, safety, RF exposure, radio spectrum usage, cyber security, and ongoing conformity obligations. It also explores practical technical challenges, such as the impact of enclosure design on module performance, changes to hardware or firmware, modular approval limitations, and managing multi‑radio systems. Throughout, the guide emphasises the importance of thorough risk assessment and informed decision‑making to ensure that final products remain compliant once the radio module is integrated.

Radio Module Integration Guide: Excerpt

“The host integrator should view any significant differences between the performance of the radio module standalone, and the performance of the radio once installed into the host as a warning sign that the end product may not be compliant.”
