Particle Tracking System Offers Software, Hardware LTE IoT Module and Tracker in Turnkey Solution

Trakcker SoM

Particle’s first cellular M2M module was launched in 2015 when the company was still called Spark IO. Since then they’ve offered new modules and boards supporting recent standards like NB-IoT and/or LTE Cat-M with product likes Boron and  E series castellated modules. The company found out that most of their customers used their boards for asset tracking despite many off-the-shelf products already available, and the main reason was the ability to customize the solution. To help their customers, the company has now launched the Particle Tracking System combining a software suite with LTE IoT system-on-module and Tracker One reference product to ease the development and deployment of customized asset tracking solutions. Particle Tracking System is comprised of three main components relying on the existing Particle IoT platform: Particle Tracking Services software suite with geolocation services (mapping and geodatabase), fleet-wide device management, an open device firmware application framework to integrate with […]
