Compact voice and edge AI
Audio, local sensing and cellular expansion on a manufacturable compact platform.
Case study
Adaptable
communications
Gateway engineering that accommodates changing LoRa, cellular and Wi-Fi technologies without forcing a complete board redesign.
Challenge
Keep the product stable while radios keep moving
Incident and field communications requirements changed faster than a fixed single-radio board could follow. The programme needed dependable wired networking and the freedom to evaluate LoRa, cellular and Wi-Fi combinations as coverage, cost and regulation shifted—without restarting schematic, layout and certification from scratch each time.
Programme constraints
- Stable compute and Ethernet backbone
- Replaceable radio modules for trial and deployment
- Field installation options including power over Ethernet where needed
- Software that survives radio swaps without a full platform rewrite
Approach
Isolate fast-moving radios from the core platform
Core platformi.MX 8M Mini class gateway with dual Gigabit Ethernet
ExpansionM.2 and mini-PCIe paths for cellular and other radios
Local wirelessWi-Fi and LoRa options evaluated as programme needs evolved
PowerPoE-ready field installation considered for remote sites
SoftwareBoard-specific Linux with clear driver and container boundaries
Change strategySwap modules and bring-up paths instead of redesigning the whole PCB
Outcome
Network choices stopped dictating the product redesign cycle
Communications options could be qualified and swapped while the compute platform, industrial interfaces and Linux maintenance path remained coherent. That shortened the loop between field learning and the next hardware iteration, and kept manufacturing conversation focused on a reusable gateway foundation.
What this demonstrates
- Resilient gateways need modular radios, not fixed modem assumptions
- Ethernet and power design can stay stable across radio generations
- EDGE GATEWAY programmes inherit this adaptable communications pattern
