Sigfox Mini Standby Asset Tracker

1. Sigfox tracking device supporting GNSS positioning

2. Over 4-year standby time

3. Mini size ultra-thin design

4.   Resistant to existing jamming techniques

5. Ideal for asset monitoring applications

The GL52SP is an ultra-thin designed Sigfox integrated product, targeting for stationary asset monitoring, inventory control and other tracking management applications that require both a small size and a battery life of over four years. With Sigfox Ready Class 0, the highest Sigfox certificate, the GL52SP has better network connectivity, mobility and a higher success rate when receiving information and data. According to Sigfox operators, the product is resistant to existing jamming techniques and network costs are substantially lower in low data usage applications.
