A few years ago, customers who installed mobile phone signal interference systems began to face a question: should they directly purchase new devices with 5G interference function? Or upgrade from the existing mobile phone signal interference system? The choice of these two options depends on the client's investment budget for the project. Relatively speaking, purchasing new interference devices directly will definitely incur more procurement costs, while adding 5G functional modules to existing old devices is more cost-effective. So, the question arises: What frequency bands should be added when upgrading the mobile signal interference system to 5G?
Previously, shielding devices without 5G shielding function were usually equipped with 6-8 interference modules, and the frequency band would include at least 800MHz, 900MHz, 1800/1900MHz, 2000/2100MHz, 2300MHz, 2600MHz, etc. The mobile phone signal blocking system only needs to completely cover the above frequency bands to completely block the 2G, 3G, and 4G signals of the phone. So what frequency bands are included in the latest 5G signal frequency band? In fact, the frequency division standards for the 5G frequency band vary in different countries. Taking Chinese Mainland as an example, the communication frequency bands allocated to 5G in China include 700MHz, 2600MHz, 3400MHz, 3500MHz, 4800MHz, etc. Among them,
Generally speaking, the price of signal jammer ranges from a few hundred dollars to several thousand dollars.
When upgrading the mobile phone signal interference system to 5G, it is necessary to supplement these 5G frequency bands mentioned above. Of course, in practical applications, it is not really necessary to increase each frequency band accordingly, such as the 4800MHz frequency band. Due to the limited application scenarios of this frequency band in reality, it is only used in a few occasions. This frequency band is used for private network communication. Therefore, when the upgraded mobile phone signal interferes with 5G, the 4800MHz frequency band can be directly abandoned.
Based on the above analysis, if the old mobile phone signal interference system needs to be upgraded to support the 5G standard, the new signal shielding module should focus on the following frequency bands: 700MHz module, 2600MHz module, 3400MHz module and 3500 MHz module. Of course, if the customer has a spectrum analyzer or mobile phone test tool, he can check the frequency bands used by the mobile phone in advance, and decide which frequency bands need to be added according to the final test results.
