The engineering-grade mobile phone jammer is derived from the hardware upgrade of ordinary Cell Phone Jammer Cheapest . It has a more refined workmanship, a more wear-resistant and heat-resistant appearance, faster heat dissipation, and a machine that has a continuous standby time of more than 48 hours. Generally, the machine is used in engineering construction, important examination places, and places that need to be turned on for a long time. How to choose a good engineering-grade mobile phone signal jammer? This is also very simple. As long as you use a mobile phone signal jammer of the Texin Technology engineering level, you can directly lock the antenna and turn on the machine. About the principle and characteristics of the mobile phone signal jammer. The mobile phone signal jammer scans from the low end frequency of the forward channel to the high end at a certain speed during the working process. This scanning speed can cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect it. The normal data sent from the base station prevents the mobile phone from establishing a connection with the base station. The mobile phone is manifested as a search network, no signal, no service system and other phenomena. cell phone jammer
The working principle of the mobile phone signal jammer is that in a certain frequency range, the mobile phone and the signal tower are connected by radio waves, and the data and sound transmission are completed with a certain baud rate and modulation method. So what are the characteristics of Cell Phone Jammer Cheapest ? The mobile phone signal jammer only shields the mobile phone signals in the test room, and has no effect on the mobile phones outside the test room, and will not affect the signal tower. It only shields the mobile phone signal and does not affect the normal operation of other electronic devices. It only shields the emission The downlink frequency of the signal tower does not affect the uplink frequency. The mobile phone signal jammer is simple to operate, install the antenna correctly, and it can run automatically when the power is turned on. It is green and environmentally friendly. The electromagnetic field intensity is far lower than the national standard and has no impact on the human body.
