Mobile GPS jammers are the best way to change the way you use your phone. Imagine that in a classroom, if all the students play with their phones and turn on the jammer, you can instantly regain the dominant position of the classroom. If you need to use it in a quiet place, you won't hear annoying ringtones. When you meet up with friends, avoid everyone staring at the screen and not speaking.
The correctional facility installed two cell phone jammer in the central jail to allow vulnerable inmates to smuggle cell phones into contact with staff. Since the range of the cell phone jammer is 50m to 60m, these two areas will be covered. It can prevent mobile phones from making or receiving calls. This prevents criminals and criminals from keeping in touch with their allies and engaging in outdoor activities.
DIG said the technical team will also visit central prisons in Kudalo and Coimbatore next week to install jammers. He added: "As notorious criminals, fundamentalists, LEE and Naxl have been held in Vellore, Coimbatore and Kudalor Central Prisons, the department is taking steps to install WiFi jammers in these prisons as soon as possible." Warden G Shanmugha Sundaram said , they tried the jammer on Monday and will continue to use it for the next two days. They will be fully operational on Wednesday. He said: "It will make our work easier and avoid unnecessary problems in prison."
All the GSM jammer needs to do is destroy the cell phone receiver's downlink and generate a sufficiently strong carrier frequency band to prevent the cell phone from logging onto the data channel. This can mean that no external antenna is required, minimizing potential interference with most neighboring feature elements. When devices are shut down, consider using individual rules to limit or prohibit the facility's authority to own and operate Portable Jammer devices. Potential interference can be further controlled by using leaky coaxial cables instead of distributed antenna systems.
