Teardown: Digital Matter Yabby LoRaWAN 915 location tracker

01 April 2020
The following is an overview of a teardown analysis conducted by IHS Benchmarking.

The LoRaWAN specification is a low power, wide area networking protocol designed to work in regional, national or global networks and with internet of things (IoT) requirements such as bi-directional communication, end-to-end security, mobility and localization services.

LoRaWAN can be used for a variety of applications related to the IoT such as smart cities, smart gas metering, smart healthcare, smart buildings, smart supply chain and, of course, the smart home. As communication and sensors become more important for smart everything, the need for LoRaWAN will continue to expand exponentially.

Digital Matter’s Yabby LoRaWAN 915 location tracker is a GPS tracking device that is small enough to be attached to assets and tracked without needing to frequently change batteries. The device can work on assets such as livestock, packages, bags, bicycles and more.

The device can be mounted on assets that are exposed to rain, dust and outdoor conditions and features a battery life of up to three years without needing battery changes.
