Traditional vehicle tracking systems were once the gold standard for protecting against car theft. Essentially, the technology works by connecting a small device to a car, truck, or motorcycle and then using the device’s GPS signal to keep an eye on the vehicle.

However, these devices rely on conventional cellular networks (GSM) to transmit their signals. Placing an inexpensive, portable jammer in a stolen vehicle is all a thief needs to disable a tracking signal. Or a thief may be using a digital RF handheld detector to find a tracking device that can remove it completely. Even less tech-savvy thieves know that tracking signals go dark when they hide a stolen vehicle in an underground car park or in a steel container.
