The popularization and application of 5G mobile phones have been more than three years, and the 5G mobile phone jammers, which are iteratively upgraded with 5G communication technology, have also developed and applied rapidly. The replacement of 3G or 4G mobile phone jammers has almost been completed. In this upgrading process, some customers often give us feedback: I hope that as a manufacturer, we can make the power or the coverage of the shielding signal larger, then the problem comes, the shielding distance of the 5G mobile phone jammer can be as large as possible How much do you do? Can the shielding range be made infinite?
Among the determining factors that affect the shielding distance or shielding range of a 5G mobile phone jammer, the most important ones include: 1. Transmitting power. 2. Antenna gain. 3. The installation height of the equipment or antenna. 4. Shield the obstacles in the signal transmission path. Let's analyze them one by one.
1. Transmitting power: At present, the power amplifier device that can be applied to 5G mobile phone jammers, that is, the power amplifier, the limit value of its output power is usually 100W-200W. There are not no power amplifier devices with output power greater than 200W, but there are very few manufacturers, and the output is very low. This makes the cost of power amplifier devices exceeding 200W RF power output very, very high. In a 5G mobile phone jammer, generally at least 10-12 shielding modules need to be included. If you want to pursue greater output power and shielding range, you must replace all the power amplifiers of these 10-12 modules with 200W Above, this will greatly increase the device cost of the device.
2. Antennas for 5G mobile phone jammers can be omnidirectional antennas or directional antennas. The gain value of omnidirectional antennas will generally be 2-8dBi, and the gain value of directional antennas will be much higher, reaching 10-30dBi . The higher the gain value of the antenna used, the more the transmission distance of the shielded signal can be improved.
3. The installation height of the equipment or antenna: Simply put, the higher the installation height of the 5G mobile phone jammer, the better, but this also needs to distinguish the type of equipment and application scenarios. The maximum installation height of shielding equipment for low-power models should not exceed 3 meters. The installation height of the high-power 5G mobile phone jammer, unless it is based on the height of the building, if it is installed on a hanging pole, its height will usually not exceed 8-10 meters.
4. Obstacles in the shielding signal transmission path: This mainly refers to the interruption of the signal of the 5G mobile phone jammer to continue to transmit and expand the range due to terrain fluctuations or large buildings.
Combined with the above analysis, it can be seen that the shielding distance of the current 5G mobile phone jammer must not be infinite. It is limited by the cost of the power amplifier device, the gain value of the antenna, and also by the installation height and obstacles in the installation environment.
