As we enter the era of 5G technology, customers who installed mobile signal jamming systems several years ago are now faced with a dilemma. Should they purchase new devices with built-in 5G jamming capabilities or upgrade their existing systems? The choice between these two options depends on the customer’s investment budget. While buying new shielding equipment incurs higher procurement costs, adding 5G modules to the existing system is a more cost-effective solution. However, the question arises: which frequency bands should be added when upgrading mobile signal jamming systems to 5G?

Frequency Bands for Previous Mobile Signal Jamming Systems:
Typically, older shielding devices without 5G capabilities are equipped with 6-8 shielding modules, including frequency bands such as 800MHz, 900MHz, 1800/1900MHz, 2000/2100MHz, 2300MHz, and 2600MHz. By covering these frequency bands, the mobile signal jamming system can effectively block 2G, 3G, and 4G signals.
Frequency Bands for 5G:
The frequency bands for 5G vary across different countries. Taking China as an example, the allocated communication frequency bands for 5G are 700MHz, 2600MHz, 3400MHz, 3500MHz, and 4800MHz. The 2600MHz band is an expansion of the existing 4G band, ranging from 2555-2655MHz to 2515-2675MHz. When upgrading mobile signal jamming systems to 5G, it is necessary to supplement these 5G frequency bands.
Selective Addition of Frequency Bands:
In practical applications, not every frequency band needs to be added. For instance, the 4800MHz band can be omitted as it has limited usage in real-world scenarios and is only employed for specialized network communications. Therefore, when upgrading mobile signal jamming systems to 5G, the addition of the 4800MHz band can be disregarded.
Determining the Required Frequency Bands:
To determine the specific frequency bands that need to be added, customers can utilize spectrum analyzers or mobile testing tools to analyze the frequency bands used in their specific location. Based on the test results, the customer can then decide which frequency bands need to be supplemented.
In conclusion, when upgrading an old mobile signal jamming system to support 5G technology, the addition of the following frequency bands should be prioritized: 700MHz, 2600MHz, 3400MHz, and 3500MHz. However, customers with spectrum analyzers or mobile testing tools can conduct on-site analysis to determine the exact frequency bands required for their specific needs. By considering these factors, customers can make informed decisions when upgrading their mobile signal jamming systems to support 5G technology.
