Interfering devices are devices that purify the network
The recent increase in incidents related to satellite navigation systems, whether intentional or unintentional, fully illustrates the threat to these networks. Today, because of our modern army and what is essential to our daily lives, we expect to face situations where satellite positioning systems are unavailable or damaged, and identify these threats. You must take the necessary steps to respond.
In June, the Justice Department released a report providing solutions to prevent criminal activity in prisons. We have successfully tested a signal jammer designed to block cell phone signals from smuggled cell phones in a Maryland prison. The news spread rapidly all over the world. For Brian Sterling, director of the South Carolina Corrections Bureau, the news is that sabotage technology is the best, cheapest, and most effective way to prevent the spread of mobile phones flowing into prisons. It supports the belief.
A portable jammer is a small, low-cost box that can send continuous sound to the antenna, effectively preventing the phone from making or receiving calls. Jammers are usually cheap (Google search shows many options between $ 119 and $ 650) and are easy to order online. However, critics have warned that traffic jams can have dire consequences. They believe there are many shameful reasons to support the legalization of correction system interference, including money, new system management, and criminal reasons.
Ben Levitan, a North Carolina wireless communications expert who recommends the use of calibration equipment, said: I have been in this business for 30 years. If someone is working on a new technology, they may know someone who sells equipment or owns parts. Levitan and other technical experts interviewed for this article pointed out that there are other effective solutions. You can control the proliferation of mobile phones in prisons, such as: B. A telephone company through a given whitelist to filter calls for tracking, identifying, identifying, and managing access systems for wireless signal detection systems.
The bigger problem is that the cost of calling from prison is high and prisoners need to contact their relatives. Prisoners have all sorts of ideas and they can put their cell phones in jail. In South Carolina, courier companies walked through the woods and threw smuggled backpacks into prison fences, Sterling said. The drone chased the prison yard, waited for the guards to leave the area, and then threw the phone into the prisoner's hands.
