According to data from the American Association of Vehicle Tracking and Protection Companies (ANERPV), from January to December 2019, their employees recorded more than 3,000 robberies, of which 75% were carried out by jammer holders. These devices block cellular signals, radio communications and data transmission. As a result, the device was completely isolated and its location could not be determined.
Since January 25, the Ministry of Transportation (SCT) has banned the use and sale of these devices. In order to protect network operators, in addition to providing technologies such as LBOX that automatically run security protocols to fix equipment, Mexico’s satellite tracking brand also provides anti-jamming solutions. Manuel de la Torre, CEO of Webfleet Solutions, said: “Once one of the parameters is not met, the device will paralyze the vehicle, and even if it is disturbed, it cannot move.”
Other brands have also developed other anti-cell phone jammer technologies based on Sigfox (long-range wireless network), which enables assets to be discovered even in the presence of interfering signals.
What is the difference between jammers and anti-jamming agents?
GPS devices with anti-jamming transmitters will stop recording the location of the device, but can be protected locally, that is, cut off the accelerator pedal and prevent further circulation of the device.
Despite the presence of signal blockers, devices with anti-interference capabilities can continue to report their location (approximately).
EasyTrack said: “Because of the features provided by the Sigfox network and the features we integrated into the satellite tracking service, we can find assets for many years and have a wide coverage.” FOX1 was developed. However, the question is: can the immune device receive the signal and block the device like an anti-jammer? 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 stop 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 you are not used to deactivating the motor. Security experts warn that despite the development of interference control technology, most GPS devices on the market will not initiate reactive operation when encountering signal suppression, or do not have the correct protocol configured to calibrate when blocked.
