Saudi Arabia's prison administration recently announced that it will install advanced mobile phone jammers in prisons across the country to completely eliminate the problem of prisoners using mobile phones for illegal communications. Behind this move, it is not only for security management considerations, but also a reflection and innovation on the lack of technical means in recent years. signal jammer The Saudi authorities hope to use this measure to comprehensively improve the security level of prisons and eliminate hidden dangers that may lead to social instability.cell phone jammer

　　Severe challenges of prisoners' illegal use of mobile phones

　　For a long time, Saudi prisons have been facing the challenge of prisoners' illegal use of mobile phones. Although the prison authorities have taken strict security measures and frequently checked prisoners' belongings and visitors, prisoners still obtain mobile phones through various means. GPS jammerThese devices are used to contact the outside world, plan criminal activities, and even affect the conduct of judicial investigations. The prison administration has tried a variety of means, including installing monitoring equipment and strengthening security checks, but the prisoners' coping methods are also constantly evolving, making management more difficult.Wifi jammer

　　Technological breakthroughs of mobile phone jammers

　　Faced with this dilemma, the Saudi prison administration decided to introduce mobile phone jamming technology as a solution. Jammers prevent mobile phones from connecting to base stations by interfering with electromagnetic signals, making it impossible for mobile phones to make or receive calls. Although this technology has been around for many years, how to accurately control its interference range in a closed environment has always been a technical difficulty.

　　Lieutenant Colonel Nasir Amer revealed that the jammer equipment tested this time was provided by two companies in Germany and the United States. In the past, Saudi Arabia tried to use similar equipment, but due to the wide interference range, the normal communications of surrounding residents were interfered with. Therefore, the research and development focus of the new generation of equipment is to improve accuracy so that its interference range is limited to the prison and does not affect the surrounding community.

　　Considerations for protecting the health of prisoners

　　When selecting equipment, the Saudi authorities pay special attention to its impact on the health of prisoners. Lieutenant Colonel Amer pointed out that the electromagnetic wave signals of the jammer must meet international safety standards to ensure that there will be no adverse effects on the health of prisoners and staff. To this end, the Saudi Prison Administration has cooperated with a number of international certification agencies to conduct multiple rounds of safety assessments on the equipment.

　　In this regard, King Abdulaziz City for Science and Technology has also participated in the research and development of related technologies, hoping to launch safer and more environmentally friendly jammers in the future. These new devices will be used in prisons, mosques and other places where mobile phones are not suitable to ensure that communication control in these places is more effective.
