1. Environmental detection, pilot frequency application
The core equipment of MDPB series cell phone jammer system adopts pilot frequency interference technology, so as to cover a wide range with smaller power. A complex environmental variable parameter model is established in the system database. When the system is started for the first time, the hardware will automatically detect the physical field strength and adjust the algorithm based on this, and automatically set the system shielding bandwidth based on the threshold.
2: Leading application of phase-locked loop technology
Leading application of phase-locked loop technology, synthetic frequency source accurately controls the interference range. When the system automatically sets the interference bandwidth and frequency point according to the environment, it will automatically synthesize the frequency source. The phase-locked loop technology will monitor the frequency range of the frequency source in real time. If the device temperature is too high, or other reasons cause the frequency range to change, the phase-locked loop technology will automatically adjust the frequency range to the correct range.
3: Monitor from time to time, remind in time
The command center is responsible for detecting the working status of the shielding system. The content includes important information such as the working status of the equipment, threshold setting, transmission power, and whether it is offline, and prompts alarms and prompts for maintenance.
4: Remote management, signaling level shielding
When the shielding system is activated, it will reasonably plan and allocate the actual output power of different shielding modules according to the distance and strength of the preset threshold signal source (that is, the base station of each operator). Signal interception and blocking with small transmission power and small bandwidth. The signaling-level shielding terminal of the shielding system can not only be flexibly adjusted according to the power of the shielded object, but also can realize the functions of remote equipment on-off, dynamic adjustment of the working status of the remote equipment, and remote inspection.
