This article will explore the application and prospects of high-tech shielding technology in global prison management. https://www.silencejammer.com
Illegal Mobile Phone Problems in Prisons Around the World
Problem Overview
The use of illegal mobile phones is prevalent in prisons around the world. Prisoners use illegal mobile phones to carry out criminal activities, harass victims and plot jailbreaks, posing a huge challenge to prison management. For example, in prisons in Texas and South Carolina, the use of illegal mobile phones is particularly serious. https://www.silencejammer.com...-cell-phone-blocker
Statistics
Statistics from Texas and South Carolina show that prisons in these states have confiscated a large number of illegal mobile phones in the past few years. For example, Stiles Prison and McConnell Prison in Texas confiscated 110 and 73 illegal mobile phones respectively in 2012, while Lee Correctional Institution in South Carolina has successfully disabled more than 700 illegal mobile phones since the pilot program was launched last summer. https://www.silencejammer.com...-blocker-car-signal
Introduction of high-tech blocking technology
Management access system
To address this problem, prisons in many countries have introduced advanced blocking technology. For example, Texas and South Carolina prisons have introduced a system called "management access" specifically designed to block unauthorized mobile phone calls, text messages, and Wi-Fi access.
Technical effect
These blocking technologies block illegal mobile phone signals by identifying the IMEI number of the mobile phone, thereby preventing prisoners from using illegal mobile phones to communicate. For example, Brian Sterling, director of the South Carolina Department of Corrections, pointed out that since the introduction of blocking technology, the use of legal calls has increased by nearly 70%.
Application and effectiveness of blocking technology
Preventing illegal communications
The main goal of blocking technology is to prevent prisoners from communicating through smuggled mobile phones. By blocking mobile phone signals, the blocking system can effectively prevent prisoners from plotting to escape from prison, continuing criminal activities, and harassing victims. For example, Bruce Toney, inspector general of the Texas Department of Criminal Justice, said that the blocking equipment at McConnell Prison has intercepted hundreds of unauthorized calls and text messages and discovered about 75 mobile phones or device parts.
Improving prison management
Blocking technology not only effectively prevents the use of illegal mobile phones, but also improves prison management. For example, Brian Sterling, director of the South Carolina Department of Corrections, pointed out that since the introduction of blocking technology, the use of legal calls has increased by nearly 70%. This shows that after prisoners were unable to use illegal mobile phones, they used more legal communication channels provided by prisons, which improved the communication management of prisons.
Future Development and Challenges
Technology Upgrade
Although blocking technology has achieved remarkable results in preventing the use of illegal mobile phones, with the continuous advancement of technology, the means of using illegal mobile phones are also constantly upgrading. Therefore, prison management departments need to continuously upgrade blocking technology to meet new challenges. For example, in the future, it can be considered to introduce a more intelligent blocking system that can automatically identify and intercept illegal signals.

Jammer B. | 14.07.2024 0 0
In modern warfare, GPS (Global Positioning System) has become an indispensable strategic tool. However, with the advancement of technology, the emergence of GPS jammers has brought new challenges to military operations. This article will explore the principles of GPS jammers, their applications in the military, and their impact on modern warfare.https://www.silencejammer.com
The basic principles of GPS jammers
A GPS jammer is a device that blocks or interferes with the reception of a target receiver by sending a powerful radio signal to cover the frequency range of the target receiver. This jammer can block GPS signals within a certain area (usually 5-20 meters), causing the receiver to be unable to accurately locate. GPS jammers are relatively simple to manufacture and use, which makes them an efficient and low-cost means of jamming.https://www.silencejammer.com/mobile-jammer-cell-phone-blocker
The application of jammers in the Iraq War
In the 2004 Iraq War, the Iraqis used GPS jammers to successfully interfere with the US military's GPS navigation system. McGregor reported that the Iraqis used GPS jammers during a sandstorm, which prevented the US military's cruise missiles and bombers from finding their intended targets. This incident fully exposed the risks of over-reliance on GPS navigation systems.
The U.S. military originally relied on airborne GPS and radar surveillance systems for precision strikes, but due to the interference of GPS signals, all bombs that relied on GPS navigation lost their targets. This incident highlights the importance of GPS jammers in modern warfare and their potential threat to military operations.
Technical progress of GPS jammers
In recent years, the technology of GPS jammers has continued to advance. Many mobile phone jammers can not only interfere with mobile phone signals such as GSM, 3G, and 4G, but also have the function of GPS signal interference. These jammers can set the interference frequency band to strong GPS, WiFi, UHF, and VHF signals, and cover the corresponding frequency band by transmitting radio waves, so that the receiver cannot work properly. https://www.silencejammer.com...-blocker-car-signal
This technological advancement has made GPS jammers more and more widely used in military and civilian fields. For example, in some special military fields, advanced technology reduces the impact of mobile phone jammers on GPS navigation by using special antennas that can only receive signals in specific directions.

Introduction
In the information society, the problem of phone tracking and eavesdropping is becoming increasingly serious, posing a huge challenge to personal privacy and information security. Fortunately, the emergence of jammers provides an effective means to solve this problem. This article will explore in detail the application of jammers in protecting phone tracking and eavesdropping, as well as their widespread use in various fields. https://www.silencejammer.com
The relationship between the Electronic Communications Protection Act and jammers
The Electronic Communications Protection Act (ECPA), passed in 1986, aims to protect the privacy of electronic communications. However, with the advancement of technology, this law has gradually exposed its shortcomings. According to a survey by federal judge Stephen Smith, in 2006, there were 30,000 sealed surveillance warrants nationwide. Although these surveillance warrants were eventually unsealed, most of them remain undisclosed. This means that electronic surveillance may continue even if there is no criminal behavior. Jammers can effectively block illegal monitoring signals and protect users' privacy and information security. https://www.silencejammer.com...-cell-phone-blocker
Animal-inspired positioning technology
In addition to protecting telephone communications, jammers are also widely used in other fields.
