Adaptable communications
Gateway engineering that keeps radio choices replaceable as networks evolve.
Case study
Compact voice
and edge AI
A small connected platform combining audio, local sensing, Wi-Fi and cellular expansion—developed around a board-specific Linux path rather than a disposable prototype.
Challenge
Move an intelligent interface off prototype hardware
The programme needed a compact device that could capture audio, run local sensing, talk to nearby networks and remain reachable when Wi-Fi was unavailable. Early work on general-purpose prototype boards proved the application idea, but not a credible route into manufacture, long-term software support or field updates.
Programme constraints
- Microphone and speaker path for voice interaction
- Local sensing alongside on-device processing
- Onboard Wi-Fi with cellular expansion
- Maintainable embedded Linux, not a throwaway image
Approach
One production-minded board for application and manufacturing
Hardware baselineCompact i.MX 8M Mini class platform sized for enclosed products
InterfacesAudio, sensing, USB and wireless options integrated on the board
ConnectivityWi-Fi for local operation; cellular expansion for wide-area reach
SoftwareBoard-specific Linux with containerised application delivery
SeparationPlatform software kept distinct from the voice and sensing application
LifecyclePath to remote system and container updates as the fleet grows
Outcome
Application focus without restarting the platform
The team could concentrate on the voice and sensing experience while the platform provided a supported Linux base, wireless options and a route from evaluation into volume manufacture. Customisation stayed around the product need—interfaces, enclosure fit and application containers—rather than rebuilding carrier boards and bring-up for every iteration.
What this demonstrates
- Edge-AI and voice products can start on manufacturable hardware
- Local inference and sensing belong with a maintained OS path
- Cellular expansion can be designed in without redesigning the core
