The customer does not need any debugging after receiving the signal jammer, but only needs to test the shielding effect after power on. Before the jammer leaves the factory, each frequency band is strictly debugged and aged. Delivery is allowed only after passing the test. After receiving the jammer, the customer does not need to carry out debugging. Just connect 220V mains power, and the shielding distance can be tested by mobile phone.
Because the interference distance of the signal jammer is closely related to the field environment and signal strength, the interference distance is different in different places. The interference distance of mobile phones of different operators will be different in the same field environment. This is because each frequency band of the signal jammer is output according to the maximum output power, which is generally 2-3W. However, in the same environment, the signal strength of the three operators can be divided into strong and weak, and the interference distance affecting the jammer is related to the signal strength of the mobile phones of the three operators. The stronger the signal, the shorter the shielding distance, the weaker the signal, and the farther the shielding distance. This will lead to different mobile phone shielding distances for different operators.
If the jamming distance of the Signal Jammer on site is relatively short, it is because the base stations around the jamming site are relatively close, resulting in the unsatisfactory jamming distance of the jammer. At this time, high-power machines can be replaced. It is recommended that the model produced by Nanjing Baikang Electromechanical Technology Co., Ltd. is sma-818k90. This high-power jammer has a single channel output of 10-15w. It can also customize an operator frequency band with poor jammer effect.
