The Challenge

A European pet technology company needed a universal pet tracker that would work reliably across diverse environments - from urban apartments to rural farmlands - while maintaining extended battery life and surviving rough outdoor conditions.

Multi-Environment Tracking

Traditional GPS trackers fail indoors and consume excessive power. The solution needed seamless indoor-outdoor tracking with intelligent network switching.

Impact: 95% coverage target

Global Connectivity

Different regions have varying network availability. Urban areas have 4G, but rural areas often only have 2G or require LoRa for long-range communication.

Impact: 180+ countries

Extended Battery Life

Pet owners forget to charge devices. The tracker needed 30+ days of battery life while providing real-time location updates.

Impact: 30+ day requirement

Durability Requirements

Pets are rough on equipment. The device needed to survive water immersion, impacts, extreme temperatures, and constant movement.

Impact: IP68 + 2m drop test

Our Solution

We engineered a compact, rugged pet tracker with intelligent multi-network connectivity that automatically selects the optimal communication technology based on location, signal strength, and power availability.
