Can the 5G mobile phone jammer distinguish between Internet data and voice data?
In some special places, due to confidentiality needs or management system requirements, it is not enough to freely carry or use mobile phones. In addition to prompting to actively turn off the mobile phone or temporarily keep the mobile phone, it can also be managed by installing a 5G mobile phone blocking device. However, some customers have also raised such demands: The company's regulations only require mobile phones to have the function of blocking data access to the Internet, but the mobile phone must still retain the function of answering or making calls. So is it possible to block only data access but not voice?
Before 5G communication technology was put into use, most mobile phones used 2G for voice communication and 3G or 4G for data Internet access. At that time, 2G, 3G, 4G, etc. had divided frequency band standards and frequency ranges. In that era, jammers could perform targeted blocking based on the frequency bands of various mobile phone models. In other words, in the era before 5G, jammers could basically treat voice functions and data functions separately, selectively blocking signals.
But by the middle and late 4G era, especially after the development and popularization of 5G communication technology, 4G and 5G networks are sufficient to support the same frequency band processing of voice and data. For example: using a 5G smartphone, assuming the mobile phone is connected to the base station through the 2.6G frequency band, regardless of whether the mobile phone is making voice calls, browsing websites, watching videos and other data transmission services, it will always remain in the 2.6G 5G frequency band. In this case, the conventional 5G mobile phone shielding device only provides overall bandwidth coverage and signal shielding for the 2.6G frequency band, and cannot accurately distinguish between voice and 2.6G frequency bands.
Now that 5G is widely used, voice and data themselves run together in the same frequency band. It is no longer possible to use traditional 5G mobile phone jammers to only block data Internet access but not voice.
