Vehicle security remains a persistent concern in South Africa, with criminals always finding ways to outsmart technology. A common example of this is GPS jamming, which has increased over the past few years, highlighting the need for more advanced solutions to combat vehicle theft.
The Cartrack Tag is our new solution that is unaffected by any form of signal jamming. This ensures that we find your vehicle despite attempts by criminals to block communication channels.
Let’s dive into it so you can understand why Cartrack has one of the best tracking and anti-jamming solutions out there!
GPS technology serves as the backbone for navigation, positioning, and timing in the modern-day era of telematics and other technologies that utilise it, such as self-driving cars. The increase in signal-blocking incidents presents a challenge that impacts safety and innovation.
Jamming refers to deliberate interference with signals from the Global Positioning System (GPS), radio communications, and cellular networks. Signal jamming devices were initially created for military operations to mislead the opposers about geographic locations and targets. The devices were then refined for the consumer market to ensure their privacy. However, due to other mischievous motives, the Independent Communications Authority of South Africa (ICASA) has since banned civilians and organisations from using signal jammers.
Nowadays, signal blockers pose a risk to motorists as they can be used to prevent GPS trackers from giving location updates, allowing criminals to get away with car theft. These devices can block a network that is meters away, which is also a concern for critical public safety communications, as that can prevent someone from making an emergency call.
Other types of signal jammers include Wi-Fi jammers, drone jammers, and Bluetooth jammers. Insurance companies have also warned motorists about remote control jammers, which are commonly used to interfere with a vehicle’s keyfob when locking, leaving it vulnerable to theft.
The Cartrack Tag is a device that is designed to be an extra layer of protection. It does not depend on cellular networks, which makes it the ideal solution for instances where vehicles are stolen using signal-jamming technology. The tag is wireless, which eliminates the need for additional complex wiring processes, making it easy to install into vehicles.
This tag can also be used to secure non-vehicle assets of various sizes. It can be discreetly fitted to trailers, generators, or equipment, allowing businesses to reduce the amount of time spent locating stolen or misplaced items. Ensuring asset monitoring that is unaffected by cellular networks.
When the network is blocked, both the vehicle owner and our control room services get a jamming alert. The tag then works independently, using Cartrack’s proprietary communication network to provide location updates. The tag is not a replacement for the main device, as they work together yet serve different functions.
Who can benefit from the Cartrack tag? Let’s have a look at the various reasons to invest in one:
Here are two examples of how our cutting-edge anti-jamming technology has helped recover the vehicles of many individuals and businesses:
In January 2025, Cartrack’s Recovery Team was dispatched for a stolen sedan. Our recovery team detected signal-jamming attempts, but through our advanced anti-jamming technology, they could still see the vehicle’s location. The vehicle was successfully recovered in Naledi with a signal-jamming device found on the scene.
In December 2024, the Cartrack Recovery Team was performing routine patrols when they encountered a bakkie and immediately received signal jamming warnings from our signal jamming detector.
They followed the vehicle, but when the driver noticed them, he accelerated, prompting a brief chase. The vehicle came to a standstill at a dead end, and it was safely recovered with a jamming device found inside.
Further investigation revealed that the vehicle was fitted with cloned number plates and belonged to a delivery company in Cape Town. Our control room team determined that the tracking unit was from a third-party tracking provider and did not belong to Cartrack. The owner of the vehicle was contacted, and the vehicle was handed over to the police.
Vehicle theft remains a major concern in South Africa, but Cartrack continues to bring innovations that make a significant impact. The Cartrack tag is yet another way to prove our unwavering commitment to changing the vehicle tracking industry and bringing you advanced solutions. Contact us today and invest in a backup unit!
What car trackers can't be jammed?
The Cartrack Tag is a tracking device that cannot be jammed. It is created for instances where criminals use signal jammers to conceal the location of stolen vehicles.
Can car trackers be blocked?
Yes, a signal-jamming device can be used to block vehicle tracking devices. They produce a white noise radio signal transmitted at around the same frequency as the GPS satellites used by the GPS, blocking out the signals to GPS tracking devices and navigation systems.
What is the range of GPS jamming?
The range of a GPS jammer depends on its size, power, and surroundings. Low-power jammers, which are often used for privacy purposes, can have a radius of just a few meters to several hundred meters. While the higher-power jammers have a range of several kilometres.
Can GPS jammers be detected?
Yes, Cartrack has anti-jamming technology that can detect when the signal is intentionally being blocked.
The increase in GPS jamming poses a threat to society as it impacts safety. The Cartrack Tag is our new way of ensuring that your vehicle's location is always visible. Let’s have a look!
