In addition to shielding WiFi2.4G and Bluetooth signals, the signal jammer can also shield the signals of 2G and 3G mobile phones at the same time, which is really powerful. In addition, due to the design of the car charger, the mobile cell phone jammer can also be used directly in the car, because after the Bluetooth jammer is powered off, you can use the car charger to charge it and then fully charge it.
The size of this handheld phone must avoid a strong electromagnetic environment to ensure the barrier effect and long-term stable operation. When not using the mobile phone jammer, please turn off the power in time. When used outdoors, waterproofing is very important. Do not disassemble the antenna during deterrence, so as not to affect the shielding effect. The actual shielding range may vary depending on the location of use. The effective blocking area is a circular area centered on the sword. For mobile phone signal jammers, the effective distance (30-40 meters) generally refers to the indoor distance. The shielding distance can reach hundreds of meters in outdoor areas.
The effective range of the interfering device is related to environmental conditions such as the distance of the base station and the installation location. These factors need to be carefully considered so as not to affect the shielding effect. The strength of the electromagnetic signal from the mobile phone signal jammer is very weak.
