How to upgrade the 3G and 4G mobile phone jammers purchased a few years ago to 5G jammers?
If the customer purchased the mobile phone wifi jammer from my topsignaljammer Technology Co., Ltd. a few years ago, if it is a low-power mobile phone jammer, you can contact our company to confirm the model of the radiator inside. If the radiator of the mobile phone jammer is in 2017 After leaving the factory, the original 8 modules can be increased to a maximum of 12 modules, so that there is a redundant space for 4 shielding modules to assemble the frequency band of 4G or 5G signal shielding, so as to achieve the effect of upgrading to a 5G shield. If it is a high-power model, please also confirm the model of the high-power mobile phone jammer you purchased with our company.
Some of the models have room for additional signal shielding modules in the 5G frequency band. For some models of high-power mobile phone jammers, the 5G jammer can only be upgraded by configuring the chassis and 5G frequency band separately.
