Shielding range of mobile phone jammer

Many customers come to consult and ask, what is the shielding range of cell phone jammer, 500 square meters, can it be achieved with two 20W signal jammers?

Explain the working principle of cell phone signal jammer in general

:

The jammer scans from the low end frequency of the forward channel to the high end at a certain speed during operation. This scanning speed can cause garbled interference in the message signal received by the mobile communication, and the mobile communication cannot detect the normal data sent from the base station, so that the mobile communication cannot establish a connection with the base station. Mobile communication manifests itself as a search network, no signal, no service system, etc.

For example, the radio you usually listen to is FM88.3, ​​which speaks the frequency of your city. Then, I can also get a same frequency, but my frequency, which is not reported to your local radio management committee, is illegal. To interfere with your normal radio frequency.

What you should know before you use a GPS jammer

The effective shielding range of cell phone jammer mainly depends on the following points:

  1. The power of the machine itself. Nowadays, there are many 5W machines on the market, but the actual power is less than 1W. Therefore, it must be the actual power. For low-power devices within 1W, the shielding distance is about 1-10 meters, and the shielding range is 10-30 square meters. Remember, such a machine cannot go through walls.
  2. The density of base stations near you. Now many customers buy back their phones, 2G3G calls can be blocked, but 4G cannot be blocked. Why? It's because there are base stations near you. Generally speaking, if there is a base station within 100 meters, if you buy a low-power machine, it basically does not work because the signal strength of the base station is too strong. It is recommended to buy a mobile phone jammer with a little power, the ratio is more than 2W per channel. There was a customer who had a mobile base station on the roof, and said that the jammer had no effect. No one can solve this. Unless you buy a super-powered machine.
  3. Field wall environment. What is the field wall environment? The place where you install the shield is a concrete wall or a glass partition. The general cell phone jammer will have no effect through the wall. Like many customers, come to consult us. Children play games alone in the room. Can there be a partition wall that can be screened? The price is low. In this case, it is difficult to achieve. Generally, the price of jammers that pass through walls is very high, at least above 700.

In summary, the shielding range of cell phone jammer is not solved by a single factor. It is recommended that before buying in large quantities, the best way is to test the signal strength of your installation environment with a field wall meter. The other one is to buy a few different power machines and test them to see how effective they are. Then decide which machine to choose.

Future Signal Jammer

insights into the working principle and factors influencing the effectiveness of cell phone jammers, helping customers make informed decisions when purchasing these devices.

Cell phone jammers operate by scanning across frequencies used for mobile communication and emitting interference signals. This interference disrupts the connection between mobile devices and base stations, rendering them unable to establish a connection. Essentially, jammers create a "no signal" zone within their effective range.

Factors Affecting Shielding Range

:
  • - Power of the Jammer: The effectiveness of a cell phone jammer is directly related to its power output. Low-power devices may have a limited range, typically around 1-10 meters, suitable for small spaces like rooms. Higher-power models can cover larger areas, with some capable of reaching distances of hundreds of meters.
  • - Proximity to Base Stations: The presence of nearby mobile base stations can impact the jammer's performance. Strong signals from nearby base stations may overwhelm the jamming signal, reducing its effectiveness. In such cases, choosing a jammer with higher power output becomes necessary to counteract the strong base station signals.
  • - Environmental Factors: The composition of the surrounding environment, particularly walls and partitions, can influence the jammer's ability to penetrate and effectively block signals. Concrete walls or glass partitions may hinder the transmission of jamming signals, limiting the range of the jammer.

Testing and Selection

:
  • - Before purchasing cell phone jammers in bulk, customers are advised to conduct thorough testing in their specific installation environment.
  • - Using a field wall meter can help assess the signal strength and penetration capabilities of potential jamming devices.
  • - Testing multiple jammer models with varying power outputs allows customers to determine the most effective option for their needs.

effectiveness of a cell phone jammer is influenced by multiple factors, including power output, proximity to base stations, and environmental conditions. By considering these factors and conducting proper testing, customers can select the most suitable jamming device to meet their requirements effectively.
