Does the customer need to debug after receiving the full-band signal jammer?
Before the full-band signal jammer leaves the factory, each frequency band is debugged and passed the aging test before it is allowed to be shipped. Customers do not need to debug after receiving the full-band signal blocker. They only need to connect 220V mains power to test the shielding distance through the mobile phone.
Since the shielding distance of the full-band signal jammer is closely related to the site environment and signal strength, the shielding distance is different in different places. Mobile phones of different operators have different shielding distances in the same field environment. This is because each frequency band of the full-band jammer is output according to the maximum output power, generally 2-3W, but in the same environment, the signal strength of the three major operators is different, which affects the shielding distance of the full-band signal jammer It is related to the mobile phone signal strength of the three major operators. The stronger the signal, the shorter the shielding distance, and the weaker the signal, the longer the shielding distance. As a result, different operators' mobile phones have different shielding distances.
