IoT Tracker with LTE and beacon technologies

Accent Systems introduces its new LTE device. It’s an evolved beacon: an IoT tracker with LTE and beacon technologies, designed to get maximum efficiency and precision in indoor and outdoor locations. It allows you to collect data in real-time and with extremely low power consumption: its battery can last years (depending on the use case).

The device sends information directly to the cloud thanks to LTE cellular connectivity. This is because Accent Systems has once again opted for two communication technologies that allow to optimize the transfer of information and guarantee low energy consumption: Narrowband-IoT (NB-IoT) and LTE-M.

The IoT Tracker is designed to improve processes in the logistics sector, especially for making an exhaustive cold chain monitoring. Not only geolocate but also gathers data from temperature and shock and sends it to a platform where see results immediately.


This is one of the multiple use cases of Accent Systems IoT Tracker, with LTE and beacon technologies. It is a highly and intuitive configurable device, and also allows each customer and/or developer to create their own application according to their needs.

Architecture of the solution

If we return to the logistics sector example, in particular cold chain monitoring, we will install the IoT Tracker on the product or products we want to hold at a particular temperature. The device will send real-time location and temperature and, if it is out of range, will send an alert. This will let know if the cold chain has been broken and detect which has been the problem to fix it and even prevent it. In addition also will have clear proof of delivery.

The device is not only designed for outdoor and moving objects, but also to locate assets, for example, inside a warehouse. Thus, a transport company that install an IoT Tracker on the goods stored in the warehouse can speed up their processes because the assets will be always located and know their status in real time.

Which geolocation systems uses the LTE Beacon?

This LTE device can act as a beacon, as a tracker and as a gateway. Three possibilities that make it very versatile and open up the range of possibilities and use cases. The IoT Tracker uses different positioning systems:


To achieve maximum accuracy in indoor location, we have devised a solution that combines traditional beacons and the new IoT Tracker, that would be acting as a gateway.



Device can be located outdoors thanks to the WiFi networks which located around.



The device uses all these satellite technologies to solve the position: GPS, GLONASS, Galileo and BeiDou/Compass, QZSS.


The device itself can also act as a beacon.

How and where is the information shown?

The information collected by the device is sent directly to the cloud, through NB-IoT or LTE-M. To display the data, Accent Systems has developed the platform Inmolecular, an IoT ecosystem that allows clients to manage all their devices.

The ecosystem is a base layer, that processes information, and different applications, which may be the standard Accent Systems offers or be carried out by the user. These applications are used to display the information collected by the IoT Tracker, with LTE and beacon technologies.

Build an application on the core of Inmolecular guarantees super secure communications, end-to-end encryption of the information and battery optimization.
