Can a 5G wireless frequency jammer only interfere with data and Internet access without interfering with voice?

Can 5G wireless frequency jammers interfere with data access without affecting voice?

With the widespread popularity of 5G smartphones, almost everyone, except the elderly and children, owns a mobile phone. But in some special places with strict confidentiality or management systems, unrestricted carrying or use of mobile phones is not allowed. In addition to requiring individuals to manually turn off their mobile phones or temporarily store their mobile phones, the most effective solution is to install 5G jammers. But some customers have a specific requirement: they only want to interfere with the data access function of the mobile phone while retaining the ability to make and receive calls. This raises a question: Can 5G wireless frequency jammers on the market only interfere with data access without affecting voice?

If we look back five or even ten years ago, 5G communication technology was not yet in use. Mobile phone voice communication mainly relied on 2G networks, while 3G and 4G networks were mainly used for data Internet access. Moreover, the mobile phone standards of 2G, 3G, and 4G at that time had strict regulations on frequency band standards and ranges. In that era, mobile phone RF jammer manufacturers could carry out targeted interference on the frequency bands of different mobile phone formats, that is, before the emergence of 5G, Cell Phone Jammers could distinguish between voice and data functions and selectively interfere with signals.

But in the late 4G era, especially with the full development and popularization of 5G communication technology, 4G and 5G networks have been able to handle voice and data in the same frequency band. For example, when using a 5G smartphone to connect to a base station via the 2.6GHz band, the phone will maintain various data transmission services such as voice calls, web browsing, and video playback in the 2.6GHz 5G band. In this case, traditional 5G RF jammers cannot accurately distinguish between voice and data in the 2.6GHz band because they only provide overall bandwidth coverage and signal interference for the band. In fact, voice and data are transmitted together in the same frequency band.

Therefore, it can be concluded that in the context of the widespread adoption of 5G today, traditional 5G RF jammers cannot interfere with data access alone without affecting voice.
