You cannot hardwire a GPS tracker to a cargo container. You cannot run wires through a portable generator or a trailer that needs to be detached and reattached. Some assets simply need a wireless, battery-powered solution that attaches magnetically, survives outdoor conditions, and lasts months without charging. That is exactly what a magnetic GPS tracker is designed for.

What Is a Magnetic GPS Tracker and Who Needs One?

A magnetic GPS tracker is a self-contained, battery-powered tracking device with one or more powerful neodymium magnets embedded in its housing. The magnets allow it to attach securely to any metallic surface — the chassis of a truck, the frame of a trailer, the base of an industrial machine, or the body of a cargo container — without any wiring, drilling, or modification to the asset being tracked.

The long battery life (typically 3-6 months in standard tracking mode) means these devices can operate independently for extended periods without needing to be retrieved or recharged.

Who Needs a Magnetic GPS Tracker?

AlikeGPS LG300: India's Leading Magnetic Asset Tracker

The AlikeGPS LG300 is specifically designed for high-value asset and cargo tracking applications in the Indian logistics environment. Here are its key specifications:

Battery Life	Up to 6 months (standard tracking mode, 30-min update interval)
GPS Accuracy	±5 meters (GPS + GSM combined positioning)
Weather Rating	IP67 — waterproof up to 1 meter depth
Magnet Strength	1,500 N pull force — withstands highway vibration and monsoon conditions
Update Interval	Configurable: 1 min (active mode, 2-week battery) to 60 min (standby, 6+ months)
Motion Sensor	Built-in accelerometer — activates GPS update on movement detection
SIM Card	Pre-installed Airtel SIM — works across India including remote highways

Key Use Cases in the Bihar and Eastern India Logistics Context

Tracking Cargo from Patna to Kolkata or Delhi

High-value cargo shipments from Bihar's trading hubs in Patna, Muzaffarpur, and Bhagalpur to major cities are particularly vulnerable to diversion, pilferage, and route deviation. A magnetic LG300 tracker attached to the cargo pallet or container provides the consignor with live visibility into the shipment's location throughout the journey — without requiring any cooperation from the carrier or transporter.

Construction Equipment Tracking at Remote Sites

JCB excavators, concrete mixers, and generators at construction sites across Bihar are frequently stolen or misused by operators for unauthorized private hire. A magnetic LG300 attached to the equipment's metal chassis provides location tracking without any wiring — and the motion sensor activates the GPS when the equipment moves, maximizing battery life during idle periods.

Detachable Trailer Monitoring

Trailers are notoriously difficult to track because they don't have their own electrical systems. When disconnected from a truck, a hardwired tracker on the truck stops tracking the trailer's location. The LG300's battery-powered design means it tracks the trailer independently — whether it is attached to a truck or parked at a depot.

Smart Motion Activation: The Battery Life Secret

The LG300's standout feature for battery life optimization is its smart motion activation system. The device's built-in accelerometer continuously monitors for movement. When the asset is stationary, the GPS module enters a low-power sleep state and transmits location only at the configured long interval (30-60 minutes). The moment the device detects movement — even slight vibration from being picked up or moved — the GPS immediately activates and begins transmitting real-time updates at the short interval (1-5 minutes).

This means a cargo container that sits in a warehouse for 3 weeks barely uses any battery. But the moment it is loaded onto a truck and starts moving, you receive real-time tracking updates with no action required from you. The intelligence is automatic.

"We ship machinery parts from Patna to Mumbai monthly. We had a consignment diverted once and lost ₹4 Lakh. Since adding LG300 trackers to our pallets, we have complete visibility throughout the journey. The driver tried to take a 200 km detour once and I called him immediately with the GPS data. He corrected the route within 10 minutes."
