Emf Shielding For Cell Phones Block Signal Is Ideal

We know that every high-tech product was invented because people had this need, such as a cell phone, because it was easier for those who needed it to communicate than before, including the now common 4G cell phone. But the 4g signal that many people are using now, while people who suffer from loud phone calls complain and make sure it's quiet in conference rooms, classrooms and places like late at night where people need to sleep Emf Shielding For Cell Phones Block Signal is a must for people. cell phone jammer can cut off the 4G mobile phone signal to ensure quietness. So 4G cell phone blocker can also prevent 4G tracking devices from working. Want to get out of being stalked, or get quiet conditions that meet life or other situations. 4G cell phone jammer can help you. Still others want to cut off both WiFi and Bluetooth signals, or when they need it, if this gets a WiFi 4G signal interfering with the device, having an adjustable feature is ideal.

Everyone thinks that the greater the power of Emf Shielding For Cell Phones Block Signal , the farther the shielding effect will be. In fact, this is not entirely correct. Many manufacturers take advantage of the fact that ordinary users cannot detect the actual power, and deliberately exaggerate the power of the shielding device for publicity, resulting in the nominal power index of the equipment. lose its reference value. For a large-scale shielding system, the shielding technology used is the decisive factor for the shielding effect. The advantages brought by advanced shielding technology far outweigh the output power factor of the shielded device. The mobile phone signal jammer uses a directional antenna to avoid external interference, which is also incorrect, because the directional antenna covers the main lobe, side lobe and back lobe, and the main lobe coverage angle is defined as the deviation from the main lobe axis. angle of time. That is, the radiation intensity from the side and rear of the directional antenna is only much lower than the main lobe. Therefore, if the space close to the antenna still has considerable shielding power, coupled with the reflection of the shielded building, it will still cause external interference. Moreover, if it is not applied properly, it will cause uplink interference, and its interference range will be larger. Therefore, whether the equipment technology can meet the conditions, the application of the antenna, and the debugging of the system are far more meaningful than whether the directional antenna is used.
