The shielding effect of indoor mobile cell phone bug detector jammers is reduced
New Delhi: Four years after the fourth-generation cellular service started operating in the country, prison inmates’ rampant use of mobile phones has increased and they decided to upgrade their interference system from 3G to 4G. Since prisoners are known to use 4G SIM cards to make VoIP calls and keep in touch with their employees, cell phone jammer installed in prisons that can block 3G signals are almost unusable. The director general (prison) Sandeep Goel, who took office last month, said that part of his goal is to stop the use of mobile phones in prisons, which is the main concern of the Delhi police. Earlier this year, a Rohini businessman even received a WhatsApp video call from Tihar prisoner Rahul Kala, asking for a payment of 5 million rupees. Kara also sent him a photo he clicked with Don Neeraj Bawana. The police followed up the prison phone and submitted a report to the prison authorities.
Different environmental impacts are also different. An open area has a larger interference area than an area with more buildings. Therefore, the measured interference radius is usually better than the actual area. Because the test is in an open place. Since the signal may be blocked/interfered by stone walls, the grid will form a Faraday cage (including "fake" lead windows) and metal like tin foil insulators, thereby reducing the reliability of the cell phone bug detector jammer indoors. In other words, if you use a cell phone jammer indoors, the glass may block the signal due to the wall. You may not be able to interfere with the signal in another room. These are several factors that affect the interference radius. Of course, there are other aspects of the impact, such as: B. Temperature of interference equipment.
