Mobile jammers are the best way to change the way you use your mobile phone. Imagine in a classroom, when all the students are playing the phone and turning on the jammer, you can immediately regain the dominance of the classroom. When you need to use it in a quiet place, you will not hear annoying ringtones. When meeting with friends, avoid everyone staring at the screen without talking.

This may mean that no external antenna is required, which minimizes potential interference to most adjacent attribute units. When the unit is in close proximity, consider using individual rules to restrict or prohibit the facility’s authority to own and operate interfering equipment. By using leaky coaxial cables instead of distributed antenna systems, potential interference can be further controlled.
