Signal interference: we answer all your questions
Q: Can technology offset the obstruction of tracking devices in passenger cars, trucks and trailers?
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.
Q: Can you explain the Altech Netstar solution?
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.
Q: So your new Resist ™ jammer system can detect jamming signals and take action without my intervention?
Yes, it’s that simple.
Q: Is your new system perfect?
We first deployed anti-jamming technology in 2009 and refined and tested it using many different jamming devices (the portable jammer technology was recovered in the vehicle recycling operation) 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 transfer situations. we are at
Q: What independent reports do you need to provide to prove that your radio network is not affected by GSM interference?
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.
Q: How do you know these different interference devices?
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 already have a lot of 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.
Q: Are criminals increasing their use of interference equipment?
There is no doubt that interference devices have proliferated, and soon all hijackers will have one.
Q: Is Jamming Resist ™ the first in the industry?
We do n’t know which competitor ’s system in South Africa or the world can meet the three main requirements, namely resistance to interference:
Can the device detect signal interference?
If yes, does it send an emergency signal?
If yes, is the frequency of this emergency signal different from the blocked frequency?
