Thieves can obtain illegal GSM jammer equipment. Sizes range from small portable devices to large briefcases. They send signals at the GSM frequency, which prevents the GSM tracking device in the vehicle from receiving and sending messages.
Yes, the signals transmitted by these illegal devices will form bubbles around the vehicle and very effectively “silently” track the device, and no one knows what happened. This is what happened recently in Congress, when a large GSM jamming device was deployed, which can effectively block all GSM signals in the House of Representatives during the US Congress.
Yes, he can. Tracking equipment has three main requirements to resist interference. First, the device must be able to detect signal interference. Second, he must then send an emergency message to tell someone “I am trapped.” The third and most important is that it must be able to send this emergency message at a frequency different from the blocking frequency. Beware of impostors-if there is no other unimpeded frequency, the solution will fail.
Our solution is called Jamming Resist ™. We have a private radio network covering all important areas of southern Africa. In this network, we have many dedicated radio frequencies, different from GSM frequencies. Our newly launched GSM tracking device is multi-functional and able to detect signal interference. Then, it immediately activates the recovery label. The beacon sends emergency messages to our control center via the standby frequency and begins to recover.
We deployed anti-jamming technology for the first time in 2009, and used many different signal jammer devices (recovered in vehicle recycling operations) to improve and test it in the past six months. All tests passed. Many of our large corporate customers have independently tested Jamming Resist ™ to their satisfaction. However, large industrial jammers (which may be as large as suitcases) that can capture a large area may interfere with our frequency. Fortunately, these devices are very expensive, difficult to obtain and difficult to use in the case of hacking. we are at
In April 2013, Carte Blanche tested the interference of our private frequency using GSM interference equipment. The test failed, and we proved that the GSM jammer placed by the investigator in the vehicle would not interfere with our private frequency.
We respond to about ten hijackings every week, we suspect that jamming equipment is used, and we have recovered many devices that have been extensively tested. Thanks to our internal expertise in radio networks, radio frequency monitoring equipment and GSM positioning equipment, we believe that we have sufficient information. We have been in the industry for more than 21 years, and to show the size of Altech Netstar, we receive more than 40 million messages every day! These come from our radio frequency equipment, GSM equipment and satellite communication equipment. Of course, our company can customize jammers.
