Where can I buy a cell phone signal blocker?
With the booming mobile communications industry, smartphones have become ubiquitous in our lives, greatly facilitating our daily lives. However, misuse of these devices can occur in places where their use is prohibited. For example, cell phones can leak confidential information in meeting rooms; phones can be used to cheat during various exams; and children become addicted to mobile games, staying up late at night and affecting their rest and study.
In these situations, a cell phone signal blocker is often needed to block mobile network signals. So where can I buy one?
In fact, cell phone signal blockers can be purchased online and in physical stores. For example, you can buy them directly from mainstream e-commerce platforms like JD.com, Taobao, and iGougou, which is very convenient. However, choosing the right cell phone signal blocker is not always easy. There are many cell phone signal blocker brands, and each brand uses different motherboards, with varying prices and power levels. It's recommended to consult with the seller before purchasing and ask them to recommend a suitable signal blocker model.
Cell phone signal blockers are primarily designed for use in places where mobile phone use is prohibited, such as exam halls, schools, gas stations, churches, courtrooms, libraries, conference centers (rooms), theaters, prisons, and detention centers. The shielding radius varies depending on the jammer's power, generally ranging from 1 to 100 meters. Cell phone signal jammers only block cell phone signals and do not affect other electronic devices.
Cell phone signal jammers work by creating garbled interference in the incoming signal, preventing the phone from detecting legitimate data sent from the base station and establishing a connection with the base station, thus preventing the phone from communicating or accessing the internet.
Factors that determine the range of a cell phone signal jammer include the jammer's power, the distance between the jammer and the base station, and any obstructing obstacles. To achieve the same shielding effect in the same area, it is recommended to use multiple low-power jammers distributed across the area. This is much more economical than using a single high-power signal blocker.
