network interceptor price in bd

The first thing to be clear is that the cellular jammer can shield 4G network signals. The mobile phone is operating within a certain frequency range. The mobile phone and the base station are connected by radio waves, and the data and sound transmission is completed with a certain baud rate and modulation method. Aiming at this communication principle, the mobile phone signal jammer scans from the low-end frequency of the forward channel to the high-end at a certain speed during operation. This scanning speed can cause garbled interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data announced from the base station, so that the mobile phone cannot establish a connection with the base station. The mobile phone is manifested in the phenomenon of searching the network, no signal, no service system and so on.
