In the world of logistics and asset management, knowing where your equipment, vehicles and valuable goods are at all times is critical. Companies that manage fleets, shipping containers, construction machinery or other high‑value assets rely on location data to improve efficiency, reduce losses and ensure that items arrive safely. However, a common pain point for many GPS trackers is battery life. Devices that transmit location data continuously may need to be serviced every few weeks or months, which raises maintenance costs and risks losing visibility if a tracker runs out of power unexpectedly.
EELINK, a leading manufacturer of wireless tracking solutions, has addressed this problem with the GPT48 ‑X. Built for long‑term deployment on fixed or mobile assets, the GPT48 ‑X combines a huge battery with low‑power networking and multiple positioning systems to deliver reliable tracking for years without a recharge. In this article we take a closer look at how this device works and how it can transform your asset management strategy.
Ultra‑long battery life
At the heart of the GPT48 ‑X is an 8 000 mAh zero self‑discharge lithium manganese battery. When the tracker is configured in its “long‑standby” mode it can report a position once per day and still last up to five years. In real‑world deployments this means you can attach a tracker to a container or flatbed trailer and leave it in place for an entire lease cycle without worrying about changing batteries.
This exceptional endurance is made possible by a combination of high‑capacity cells and a smart power‑management system. When no motion is detected, the device goes into a deep‑sleep state where its power consumption drops to microamps. A built‑in motion sensor wakes the device automatically when it detects movement and an over‑the‑air command can also bring it online for real‑time tracking. By balancing daily “heartbeat” reports with occasional high‑frequency updates during critical events, the GPT48 ‑X can provide both long battery life and timely location data.
Multi‑network connectivity
GPS trackers are only as reliable as the networks they depend on. In many remote or indoor environments, traditional 2G/3G networks either cannot reach or consume too much power. The GPT48 ‑X solves this problem by supporting both LTE Cat M1 and NB‑IoT, the two leading low‑power wide‑area (LPWA) technologies. LPWA networks are designed to carry small amounts of data over long distances using minimal energy. Because many mobile network operators around the world are rolling out Cat M1 and NB‑IoT coverage, the GPT48 ‑X can maintain connectivity even in areas where other cellular technologies struggle.
The tracker also uses multiple Global Navigation Satellite Systems (GNSS) – GPS, BeiDou and GLONASS – to calculate its position. Using signals from three constellations rather than one improves accuracy and reliability, especially in dense urban areas or along mountain passes. If the device cannot obtain a satellite fix, it can fall back to cell‑tower and Wi‑Fi positioning to provide approximate location data. This hybrid approach means your assets remain visible even in challenging environments like warehouses, ports or underground parking garages.
Intelligent sensors and alarms
A long‑life battery would be useless if the tracker remained silent when something important happens. To make sure you always know when there is a problem, the GPT48 ‑X includes a suite of intelligent sensors. A vibration and motion sensor wakes the device when it moves and triggers a move alarm if it was not scheduled to depart. Additional sensors detect drops, collisions or attempts to remove the unit from the asset. When any of these events occur, the tracker immediately sends an alert to your cloud platform or mobile app.
The device also supports geofencing. You can define virtual boundaries around construction sites, warehouses or delivery zones and receive notifications if an asset enters or leaves the area unexpectedly. Coupled with the motion sensor, geofences provide an early warning against theft or unauthorized use.
Remote configuration and OTA updates
One of the challenges of managing hundreds or thousands of trackers is updating settings or firmware after they have been deployed. GPT48 ‑X addresses this by offering remote configuration over the air and by supporting OTA firmware upgrades. Fleet managers can change reporting intervals, switch between long‑standby and emergency modes, or install new features from a central console without visiting the device. This reduces maintenance costs and ensures that your trackers remain secure with the latest patches.
Flexible working modes
Different assets require different tracking behaviour. A container being stored in a yard might only need to report its location once per day, while a truck that has been stolen needs real‑time tracking. The GPT48 ‑X provides both scenarios through two working modes. In long‑standby mode the device sleeps most of the time and wakes on a schedule to send a report. In emergency mode it can be woken up via SMS or the cloud platform and configured to transmit location data at much shorter intervals such as every minute. After the incident is resolved you can switch back to the low‑power mode to preserve battery life.
Compact design and easy installation
Despite its large battery, the GPT48 ‑X is compact and rugged. The body is about 101×60×25 mm and weighs roughly 130 g. The housing is sealed and rated to operate from –20 °C to 60 °C, making it suitable for use in shipping containers, refrigerated trailers and other outdoor environments. A strong magnetic mount on the back allows you to attach the tracker to metal surfaces such as trailers, machinery or forklifts without drilling holes or running wires. There is also a configuration port if you need to connect a USB cable for initial setup.
Technical specifications
The GPT48 ‑X houses an 8 000 mAh battery rated at 3 V and uses advanced lithium manganese chemistry to minimize self‑discharge. It supports LTE Cat M1 and NB‑IoT with global bands including B1, B2, B3, B4, B5, B8, B12, B13, B18, B19, B20, B26 and B28. GNSS accuracy is around two meters and the tracker can wake from a cold start in about 30 seconds, from a warm start in 10 seconds and from a hot start in less than one second. A waterproof design protects the electronics, and the magnetic mount uses strong rare‑earth magnets to keep the device firmly attached to metal surfaces.
Integration with management platforms
While the hardware is impressive, the true power of a modern GPS tracker comes from its software ecosystem. The GPT48 ‑X integrates seamlessly with EELINK’s Keelin platform, which provides cloud‑based dashboards and mobile apps for real‑time tracking, history playback, geofencing and analytics. The device also supports open protocols so it can be integrated with third‑party systems such as supply chain management software, telematics solutions or enterprise resource planning platforms. Data from the tracker can be routed to your systems via APIs, ensuring that you retain ownership of your operational insights.
Real‑world applications
The combination of long battery life, multi‑network connectivity and intelligent alarms makes the GPT48 ‑X ideal for a wide range of applications:
- Long‑haul trucking and freight: Install trackers on trailers or flatbed trucks to monitor their location during long journeys, especially across borders where network availability is inconsistent. If a trailer deviates from its route, you receive an alert and can dispatch security or adjust dispatch plans.
- Shipping containers and pallets: Attach the device to containers or pallets to ensure that shipments are not opened prematurely or stolen. Geofencing can notify you if a container leaves a port or logistics hub without authorization.
- Railcars and heavy equipment: Rail operators and construction companies can track locomotives, wagons, cranes or earth‑moving equipment. The vibration sensor warns if equipment is being operated outside scheduled hours.
- High‑value assets: Businesses that store valuable generators, fuel tanks or construction materials on job sites can deter theft by using the GPT48 ‑X. The tracker’s magnetic mount makes it easy to hide and remove, and its long battery life means thieves are unlikely to find a device that needs frequent recharging.
A step towards sustainable logistics
Beyond security, long‑term tracking devices also contribute to sustainability. By providing continuous visibility into asset location and utilization, fleet managers can optimize routes, reduce idle time and avoid empty miles. When assets are used more efficiently, fuel consumption drops and greenhouse‑gas emissions decrease. Many customers have reported lower operational costs and improved utilization rates after deploying EELINK trackers.
