How far can the low-power 5G mobile phone signal Jammer device be installed in the car?

Many customers have expressed their desire to install 5G jammers in the car for easy transportation and flexible change of use locations. However, due to limited budgets, they often choose low-power shielding devices. In this case, it is very important to determine the range that can be effectively shielded using this method.

First, we need to understand the specific requirements of the customer. Do they want to shield the signal inside the car or the signal outside the car?

For customers who only need to shield the signal inside the car, it is relatively simple to implement. The metal structure of the vehicle provides a certain degree of isolation. Low-power 5G Cell Phone Jammers can be powered directly using the cigarette lighter interface. This type of device is usually able to completely shield all mobile phone signals in the car and effectively achieve the desired effect.

On the other hand, some customers’ goal is to shield the signal outside the car, and even try to shield the mobile phone signal outside the car for more than 100 meters. In this case, it becomes unrealistic to rely on low-power 5G mobile phone signal jammers. Low-power shielding equipment has limited transmission power, generally around 2-3W per frequency band, and the mobile phone signal strength outside the car is generally more than 10dB higher than that inside the car.

In most outdoor environments, the effective shielding range of a low-power mobile phone jammer installed outside the car is only 2-5 meters, and the actual shielding effect is limited to a short distance around the vehicle.

In order to achieve a large coverage range of the vehicle-mounted 5G mobile phone jammer, high-power shielding equipment is essential. However, there are obvious disadvantages in choosing a high-power jammer, such as increased weight, volume, and power consumption. The installation process also requires vehicle modification, antenna installation, power adjustment, etc.

Therefore, when choosing a mobile phone jammer suitable for vehicle installation, these factors need to be considered, including specific requirements, budget constraints, coverage, etc.
