Business Description

Amplitec mobile cell phone signal jammer is used to block mobile phone 2g 3g 4g 5g and wifi gps bluetooth etc...

Shielding effect is affected by local signal strength. For example, someplace signal strength is -60dB, signal jammer can block about 150m2, but someplace strength is -20dB, signal jammer only can block 10m2 even no effect. But -60dB and -20dB they both show 5 full bar mobile phone signal, but the actual effect is very different.

It uses frequency multiplication, frequency division, frequency hopping filtering and other technologies to analyze the required shielding frequency for the uplink and downlink channels of the mobile phone system; customizes a spherical shielding space according to the power of the shield, and automatically forms a shielding magnetic field within the specified range. Make mobile phones disabled in this space. When the jammer is in working state, it can disable the function of sending and receiving signals of mobile phones within a specified range, and cannot dial out or dial in, so as to achieve the purpose of mandatory disabling.

Introduction to the principle of mobile phone signal jammer (shielding device), according to the above communication principle, the jammer scans from the low-end frequency of the forward channel to the high-end frequency at a certain speed during the working process. The scanning speed can cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station. The mobile phone manifests as the phenomenon of searching the network, no signal, no service system, etc.
