The State Secrecy Bureau once organized five domestic product manufacturers to conduct tests and allow qualified products to be sold. However, from the perspective of inspections by the Radio Regulatory Commission and national secrets, some of them are not standard, even for certain products. The interference caused by China Mobile's base station and China Unicom's interference also stopped the sales of factory products. Subsequently, the State Secret Service introduced a new standard at the beginning of this year, which will replace the seven new suppliers that have been vetted to become legal products and the companies that have used products in the past. At present, more than 100 companies in China produce cell phone jammer for mobile communication phones, of which Shenzhen accounts for nearly one-third. Among the product lines that have emerged, the lowest price is the price of pens and mobile phones, the price is between 1,000 to 2,000 yuan, and the high-end price is between 1.8 million and 3 million.
Power mobile phone jammers are used in many places, so what kind of electronic devices will jammers block? It depends on the radio waves of the signal frequency you use in your electronic device. Some people may want to buy jammers, but they are not sure whether cell phone jammers can meet their own requirements or interfere with the devices they want to block. What equipment will a mobile jammer interfere with? Here we talk. A cell phone jammer is an electronic device designed to block different frequency bands according to its specifications. These specifications may include many different frequencies at which jammers will be successfully blocked. Therefore, the key to determining whether the jammer will interfere with the device you want is to see if the operation of the device requires signal transmission.
