We know that the purpose of using a cell phone jammer is only to interfere with the mobile phone signal in a limited area, making the mobile phone unusable in this shielded area, but only interfere with the use of the mobile phone in the shielded area and cannot affect other types of electronic equipment in this area. Normal operation. In addition, it cannot interfere with the mobile phone application functions outside the shielded area, let alone the normal operation of the signal transmitting base station. Otherwise, the shielding effect is hard to say. It is reported that the electromagnetic field intensity generated by this interference signal wave is very low, which is lower than the national standard like the mobile phone signal wave, so it will not affect human health and the environment. It is a green and environmentally friendly effective interference method. Targeted implementation of interference is a technology developed based on the principle of mobile phone signal jammers. After being made into jammer products, through its use, the shielding operation can be implemented in a targeted manner, protecting the privacy and business secrets we should protect, and keeping the environment quiet and safe. disturb.
Generally, the shielding device does not need to shield the signals in all areas, but only shields the mobile phone signals in a specific area. For example, the prison in a prison is a place where prisoners are detained. The strict management of mobile phone signal shielding is implemented, so the prison must be installed in the prison. The shielding device, and set its shielding range in the prison, implement 24-hour continuous shielding, but once out of this area, the mobile phone can receive the signal and communicate with the outside world. Through the analysis of the principle of the mobile phone signal jammer, the setting of this shielding area is the space requirement for the coverage of the jammer. From a technical perspective, some jammers are subject to the limitations of current technical implementation methods, and some jammers The product also fails to meet the requirements for a larger shielding area. In other words, if the shielding area required by the customer exceeds the limit that the product can cover, two or more shielding devices are required.
