Can the frequency jammer only interfere with voice but not data?

frequency jammer

When some customers ask us about the demand for frequency jammers, they sometimes make such a request: they hope to only interfere with voice calls and not interfere with communication data. To put it bluntly, I only hope that the mobile phone cannot answer or make calls during the use of the interference device, but this mobile phone can still access the Internet normally, use chat software to communicate with the outside world, and play online games normally. So, can our frequency jammer only interfere with voice but not data?

If we go back to 10 years ago, when we were still in the 2G and 3G era, it was relatively easy for the frequency jammer at that stage to only interfere with voice and not interfere with data. Because the division of labor at that time was like this, 2G mainly handles voice call services, 3G can be used for both voice calls and data transmission, when only the voice call function needs to be reserved, only the 3G in the frequency jammer needs to be Just keep the band on. Of course, although a data communication with a very low network speed is still reserved in the 2G frequency band, such a low communication rate cannot meet the data traffic demand on the mobile application side.

Then when we have experienced 4G and entered the 5G communication era, the division of mobile phone communication frequency bands has been greatly adjusted and changed compared with 10 years ago. The original 2G frequency band has already started the frequency and network decommissioning project, and many places have already demolished the original 2G mobile phone base stations. A large part of the original 3G frequency band was changed to 4G frequency band for use. Moreover, 3G, 4G, and 5G mobile phone standards all support voice and data at the same time, which has brought about a consequence: we can no longer distinguish voice and data from the working frequency of the mobile phone. In the same way, we cannot make an effective distinction in the setting and selection of the interference frequency of the frequency jammer.

So the final conclusion is already obvious, these common frequency jammers can no longer only interfere with voice calls, but not interfere with data transmission.
