Judging from the information of various mobile phone signal jammer manufacturers, it is rare to see products that claim to have an effective shielding distance of more than 1000 meters. When we consult customers, we often receive requests to purchase or customize mobile phone signal jammers, and clearly require an effective shielding distance of 1000 meters. So can cell phone jammers<\/a> reach such a long shielding distance?<\/p>\n\n\n\n

Some customers give an example that the coverage radius of some mobile phone base stations can reach 2-3 kilometers, and high-power mobile phone signal jammers will also transmit radio frequency signals, so it should be feasible to achieve an effective shielding distance of more than 1000 meters.<\/p>\n\n\n\n

In fact, within an acceptable and reasonable production cost range, it is difficult for conventional high-power mobile phone signal jammers to achieve an effective shielding radius of more than 1000 meters.<\/p>\n\n\n\n

First of all, let us explain that the coverage radius of mobile phone base stations is based on a limited bandwidth. Usually, the transmission power of the base station is above 20W, but its working bandwidth is relatively narrow. The bandwidth of the traditional 2G network is less than 1MHz, and the bandwidth of 3G and 4G networks is only 4MHz-20MHz. With high power and narrow bandwidth, mobile phone signals can cover several kilometers. But in the 5G era where bandwidth can reach tens or even hundreds of MHz, the coverage radius of 5G base stations generally does not exceed 1000 meters. This is why 5G base stations are being deployed more and more frequently to ensure full coverage. Best-selling wifi jammers<\/a> and GPS jammers<\/a> in Europe and America.<\/p>\n\n\n\n

High-power mobile phone signal jammers also face the same challenge. To ensure effective shielding of mobile phone signals, the shielding signal of the jammer<\/a> must be 3-5dB stronger than the mobile phone base station signal, and each signal shielding module in the jammer emits a broadband signal, and the bandwidth of each module generally exceeds 50MHz or even 100MHz. Even if the total power reaches 50W or 100W, the average output power of each module will be reduced due to the large bandwidth.<\/p>\n\n\n\n

In summary, due to the limitations of frequency bandwidth, average output power and production cost, it is very challenging to achieve an effective shielding distance of more than 1000 meters using traditional high-power mobile phone signal jammers.<\/p>\n\n\n\n
