Why should you upgrade your equipment to use 5G jammers?

Some of our old customers bought 4G jammers a few years ago. In recent months, some former customers have sent me emails with questions about 5G jammers. After answering their questions, I think there are more customers who have questions about 5G signal jammers. Let's talk about 5G jammers today.

As we know, with the acceleration of 5G network construction in European countries, several frequency bands have been divided and put into use, which have become key resources for 5G networks. Among them, the 700 MHz frequency band, as a representative of the low frequency band, is widely used in many countries to ensure wide coverage and deep signal penetration. In addition, 3.5 GHz (medium frequency band) and 26 GHz (millimeter wave radio frequency band) have been included in 5G spectrum planning to support high data rates and low latency. With the introduction of these frequency bands, the 5G jammers must also be upgraded accordingly to adapt to the requirements of the new frequency bands.

Spectrum allocation and matching

Allocation of the 700 MHz frequency band

European countries consider the 700 MHz band (694-790 MHz) as an important low frequency band resource for 5G networks. According to the European Commission's plan for electronic communications regulators (BEREC):

• The 700 MHz frequency band is divided into:
• Uplink: 703-733 MHz
• Downlink: 758-788 MHz

The main objective of this frequency band is to enable broad indoor coverage and penetration, which is particularly suitable for the use of the 5G network in rural and suburban areas.

Allocation of the 3.5 GHz frequency band

3.5 GHz (3,400-3,800 MHz) is the main mid-band frequency resource for European 5G networks and is used to balance speed and coverage. The allocation of this frequency band is slightly different in different countries, but most use it for 5G use in urban and suburban areas:

Germany, for example, allocates the 3.4 to 3.7 GHz frequency range to telecommunications operators such as Deutsche Telekom, Vodafone and Telefonica.
The UK allocates 3.4-3.8 GHz to operators such as EE, O2 etc.

Introduction of the 26GHz millimeter wave frequency band

As a high-frequency band, the 26 GHz band (24.25-27.5 GHz) is planned as a millimeter wave resource for 5G in Europe to provide ultra-high-speed services with low latency, which is particularly suitable for densely populated cities, stadiums and industrial parks.

Upgrades and changes to 5G jammers

Interference in the 700 MHz band

For the 700 MHz band, upgrading the jammer is relatively simple. Due to the narrow frequency range (30 MHz), only fine-tuning of existing jammers is required to cover the 700 MHz band and meet the jammer requirements.

Interference in the 3.5 GHz band

Upgrading the jammers in the 3.5 GHz band is more difficult:

Due to the large bandwidth (400 MHz) of the 3.5 GHz band, the jammer must have a higher frequency response capability.
The improved interference transmitters must support precise frequency matching in order to avoid interference with neighboring frequency bands.

For example, when allocating the 5G frequency band in the UK, jammers must cover the range between 3.4 and 3.8 GHz to ensure signal jamming effectiveness.

Challenges due to 26GHz mmWave interference

Millimeter wave signals in the 26 GHz band are characterized by their high frequency and short wavelength. Jammers face the following challenges:

High frequency precision jamming: Signals in the millimeter wave band are easily blocked by obstacles, but the jammer must support a higher frequency range (above 24.25 GHz) to ensure effective jamming of millimeter wave signals.
Increased complexity of the devices: Millimeter wave jammers require greater technical precision and power control options.
