GPS jammer equipment still does not trigger reactive measures due to signal suppression

According to data from the American Association of Vehicle Tracking and Protection Companies (ANERPV), from January to December 2019, their employees registered more than 3,000 robberies, 75% of which were carried out by interferers. These devices block cellular signals, radio communications and data transmission. As a result, the device is completely isolated and its location cannot be seen. As of January 25, the Ministry of Transport (SCT) banned the use and sale of these devices.

To protect network operators, Mexico’s satellite tracking brand provides technologies such as LBOX anti-jamming solutions, which can automatically run security protocols to secure equipment. Manuel de la Torre, CEO of Webfleet Solutions, said: “If one of the parameters is not met, the device will paralyze the vehicle, and even if it is disturbed, it will not be able to move.” Other brands have developed other based on Sigfox (remote wireless network). “Immunity” gps jammer technology can find assets even if jamming signals are present.

GPS equipment with anti-jamming equipment will stop recording the location of the equipment, but it can be protected locally by cutting off the accelerator pedal to prevent the equipment from continuing to circulate. A device with anti-jamming capability can continue to report its position in sequence (approximately), even if there are signal blockers in the device. EasyTrack said: “Due to the features provided by the Sigfox network and the features that we integrate into satellite tracking services, we can locate assets with a wide range for many years.” FOX1 has been developed.

But the question is: can the immune device receive the signal like an anti-jamming transmitter and block the device? The answer is yes. We will explain to you. As long as the Sigfox device has a digital output, the immune system against the jammer will block the device. However, with this technique, commands can only be sent to the device every 6 hours (up to four times a day), which is why they are not used to deactivating the motor. Security experts warn that despite the further development of anti-jamming technology, most GPS devices on the market will still not trigger reactive measures due to signal suppression or fail to configure the correct calibration protocol when blocked.
