During the “State Statement 2015” speech in Pretoria, the scourge of signal interference in South Africa was revealed through Carte Blanche talks and a high-profile blockade of cellular communications. Especially the last event helps to raise public awareness and encourage tracking companies (such as Ctrack) to innovate and defend themselves.
Nevertheless, the use of signal jammers continues to spread in South Africa because they are easily available and become cheaper. As a result, today’s hijackers use a variety of jamming systems and equipment, some of which are larger and larger, while others are smaller and easy to carry. Despite the fact that according to ICASA, the possession and / or use of signal jammer equipment is illegal in South Africa.
Regardless of size, these systems often prevent telematics devices from broadcasting their location to track service providers.
Heinn Jordt, General Manager of Ctrack Fleet Management Solutions, said: “Hijackers use a series of 4G jammer systems to block communication tracking devices on cellular or satellite networks. When stuck, they usually hijack the vehicle or cooperate with the driver They move to the place where they will unload their precious goods. ”
Those in the transportation and logistics industry know that protecting trucks and their goods from theft is essential. According to the South African Insurance and Crime Bureau, truck hijacking involves all transported products and fast-moving fast-moving consumer goods such as tobacco. In any case, the fact is that most trucks are transferred to load goods.
What fleet owners and operators need is a total transportation solution that combines fleet management with the ability to detect signal interference. The good news is that there is a solution today that can provide effective anti-jam protection for trucks and trailers.
In order to mitigate signal interference, it is necessary to use the alternative frequency of the blocked frequency. This is the source of the DSSS (Direct Sequence Spread Spectrum) technology used by Ctrack. DSSS does not rely on any other format (such as GSM) for communication. Instead, use a bandwidth that is greater than the bandwidth required for the message signal to send the message.
The propagation of the signal transmitted over a wider bandwidth makes the resulting wideband signal appear as a noise signal, thereby being able to resist intentional and unintentional interference to a greater extent. What will the interference signal depend on? DSSS is also designed to transmit signals from difficult radio frequency (RF) areas, and can penetrate concrete, making it ideal for urban, commercial, and financial environments.
In March, Ctrack announced that its interference detection solution will become part of the joint fleet management software package. “Now, we are able to provide customers with the possibility to install non-GSM interference detection modules as part of their fleet management system to ensure continuous visibility and prevent vehicle theft. Mr. Yolt said.
Through the fleet management component, fleet owners can monitor driver behavior, including difficult conditions, acceleration, braking and cornering, and speeding. Monitoring factors such as engine performance and fuel consumption will also save significant fuel and maintenance costs.
