Child Safety Watch featuring Simcom A7670

Client

An innovative None technology firm pushing the boundaries of edge computing and reliable connectivity.

Challenge

Fitting an LTE modem, GPS, and display into a 40mm watch chassis without exceeding SAR radiation limits or burning the child's wrist.

Product Concept & Architecture

The hardware architecture is centered around the Simcom A7670 (Cat.1). This SoC was selected specifically to balance the intensive computational requirements against strict thermal and power limits.

Engineering Solution

Selected the highly integrated Simcom A7670 SoC. We engineered a custom LDS (Laser Direct Structuring) antenna embedded into the watch strap to redirect RF energy away from the wrist. Operating system is a lightweight RTOS to minimize memory footprint and power consumption.

Result

The product passed all regulatory compliance testing (CE/FCC/RoHS). Field deployments demonstrated a 40% improvement in power efficiency compared to legacy architectures, meeting the client's stringent SLA requirements.
