 Techniques that deliberately interfere with electromagnetic frequencies (also known as interference) have been implemented in various devices, which are gradually provided to individuals and organizations. The interference is becoming smaller, more convenient, easier to use and cheaper, although in fact in most countries in the world, the interferencer is illegal. Although certain interferencers will block communication without differentials, there are several dedicated devices that are specifically designed to prevent certain signals. Among them, the most popular is the mobile phone jammer, WiFi interference,  drone jammer , and even GPS interference. In most countries, the authorities mostly disapproving the use of these devices is that they tend to have a greater impact than expected. Even deliberate use, for example to prevent the use of mobile phones in school, theater and hospitals, or prevent drone from flying over private property, or cause interference beyond the exp...

 A  cell phone jammer  is a jamming transmitter that emits a weak radio signal to separate the connection between the cell phone and the radio base station. The interference effects can be digitally controlled to create quiet areas in restricted places. HandyBlocker is especially suitable for administrative offices, meeting rooms, conference centers, corporate headquarters, libraries, cinemas, places of worship, concert halls, high-end restaurants, educational institutions. Mobile jammers provide the ultimate solution to the above problems: mobile phones are often in meetings, Performances and other inappropriate circumstances sounded. The following are some places where mobile phones are not usually used: movie theaters, concert halls, theater records, recording studios, libraries, conference rooms, lecture halls, high-end restaurants, etc. It is a good choice to use places Yin in these places.

 Nowadays, mobile phones have become an indispensable part of life, making people's lives easier, but mobile phones also have some shortcomings. For example, in mobile phones, people may forget to appreciate the beautiful scenery around the phone. This place will bring noise. With the birth of smartphone jammers, interference with mobile phones has become easier. This is a very practical tool, it is easy to use, can quickly block cell phone signals, and has been widely used in many fields. GPS signals may also be interfered by reflections from nearby signals or other external signals (for example, under a power pole or the like). However, if you cannot receive any signal at all, no matter what you do, you should test whether the antenna of the  GPS jammer  in your smartphone is malfunctioning. You can do this through the GPS test app. Technically, it depends on the way the signal is. It is composed of electromagnetic waves and can react with the basic components of obstac...
