How to choose a 5G mobile phone jammer?

May 5th, 2022

 

5G signals usually use some of the frequency bands of 4G signals. Of course, 5G also has millimeter wave base station equipment, but most countries do not use millimeter wave equipment. Because of the short distance of millimeter waves, the construction of base stations is difficult, the cost is high, and the economy is poor.

How do we choose a 5G mobile phone jammer?

First of all, most 5G jammer on the market do not cover millimeter waves. Because millimeter waves are difficult to interfere, and most countries do not apply such bands. There are also relatively few millimeter-wave base stations.

At this time, we have to look at our local signal coverage.

—————————————–

600 (n71) / 700 (n28) MHz,

2.5 (n41) /3.5 (n78) /4.5 (n79)

—————————————–

5G600: 617-685MHz

4G(LTE): 700-825MHz

4G(WIMAX)/5G: 2500-2690MHz

5G3400: 3400-3600MHz

5G3600: 3600-3900MHz (n78)

Generally speaking, these frequency bands are commonly used in 5G.

So currently jammers.store supports most of the 5G signal shielding, and what is missing is the millimeter wave shielding.

What is mobile phone jammer?

A mobile phone signal jammer is a device that blocks reception between cell towers and mobile phones. A mobile phone jammer transmits on the same radio frequencies as the cell phone, disrupting the communication between the phone and the cell-phone base station in the tower. It’s a called a denial-of-service attack. The jammer denies service of the radio spectrum to the cell-phone users within range of the jamming device.

Why would someone use a mobile phone jammer?

Developed for use by the military and law enforcement, Cell phone jammers were originally developed to counter threats such as cell phone-triggered explosives and hostage situations.Some schools also use this equipment, as well as prisons. Usually such devices will have a distance range. Unless military-grade equipment, the scope of the impact is limited.

Do schools use mobile phone jammers?

Cell phone jammers are usually installed uniformly by schools. The purpose is to improve the quality of teaching and improve the fairness of examinations. Many teachers are tired of students watching other videos in class. Students ignore lectures when browsing SNS, and when taking exams, teachers cannot completely stop students from cheating, especially with communication devices. Installing jammers has become an effective way.

How much does a mobile phone jammer cost?

Since most high-quality cell phone jammers cost around $200 or more, there are products from different manufacturers in different countries, but most jammer manufacturers are in China.

How to choose a jammer?

Usually you need to understand that jammers are not perfect, itsĀ  principle is to jam the signal according to the frequency range. If you need to block 4G signals, you definitely need also to jammer 3G and 2G signals. At this time, you only need to choose a 4G+3G+2G device. Of course, The 4G signal has the European version and the US version. If you are not sure, you can try to choose the 4G LTE+Wimax version, which generally covers most of the 4G mobile phone signals in the world.

If you need to block GPS, for example to block trackers, you can choose GPS blocker. We also need to jammer 3G+2G mobile phone frequencies, because some trackers use base stations. Using it also prevents network connections.

If you feel that WIFI Bluetooth devices are disgusting and want to block such signals, choose a 2.4G device blocker. The frequency used for Bluetooth and WIFI is the same 2.4G. There are also 5G WIFI devices. See if you need to block the corresponding 5G WIFI signal.

The current 5G mobile phone network is under construction. There will be millimeter wave equipment in the United States. The investment in this equipment is relatively wide, and the range is small, so most manufacturers will not provide millimeter wave shielding. Because such devices consume a lot of power, the handheld jammers and traditional desktop jammers cannot take the load.

Therefore, there are bound to be trade-offs when choosing 5G devices.

About Mobile phone jammer or Cell phone jammer

Qualitative of Mobile phone jammer

A cell phone jammer or blocker is a device that intentionally transmits a signal on the same radio frequency as the cell phone, disrupting communication between the cell phone and the cell phone base station, effectively disabling cell phones within range of the jammer, preventing them from receiving signals and transmitting they. Jammers can be used in almost any location, but are primarily used in places where phone calls are particularly disruptive due to the need to be quiet, such as entertainment venues.

Mobile phone jammer is illegal to use

Because they disrupt the operation of legitimate mobile phone services, the use of such shielding devices is illegal in many jurisdictions, especially without a license. While running, such devices also block access to emergency services.
