2.6G frequency band change process in mobile phone jammer

2.6G frequency band change process in mobile phone jammer

  • 2022-07-20

With the large-scale popularization and application of the four major operators in the 5G commercial market, as a professional manufacturer of mobile phone jammers, we have also up on 5G signal jamming with the times. In the process of upgrading from 4G to 5G, the 2.6G frequency band originally allocated to China Mobile was expanded, so the 2.6G frequency band in our mobile phone jammer was also changed accordingly.

Many years ago, when the 4G communication network was deployed, the frequency range allocated by the Ministry of Industry and Information Technology to China Mobile in the 2.6G frequency band was: 2555-2655MHz, with a total bandwidth of 100MHz. When we are producing mobile phone jammers, we also correspondingly cover the jamming signal coverage of the 2.6G frequency band from 2555MHz to 2655MHz, and reserve a bandwidth margin of 3-5MHz before and after this frequency band.

With the application of 5G's high speed and high bandwidth, China Mobile's 100MHz bandwidth in the 2.6G frequency band is obviously not enough, so the 2.6G frequency band is relaxed to 2515-2675MHz. Although it can be seen in practical applications, China Mobile The most commonly used frequency range is 2535-2635MHz, but when we produce mobile phone jammers, we must achieve complete coverage. Then the problem comes. The bandwidth of 2515-1675MHz reaches 160MHz. If only one interference module is used for this 160MHz bandwidth in the mobile phone signal interference instrument, it will obviously cause the average output power to be seriously weakened. Therefore, in order to ensure the interference effect of the mobile phone jammer against China Mobile's 2.6G frequency band, we divided the 2.6G frequency band into two, or even divided into three in some special occasions, and divided the 160MHz bandwidth into two or three dozens of MHz. interference module. This increases the average output power of the mobile phone jammer in that frequency band.
