Scrambling Noise On Cell Phone
Detention centers are institutions for detaining criminals who have been arrested or detained in accordance with the law. Criminals who are sentenced to fixed-term imprisonment of not more than one year, or whose remaining sentence is not more than one year and cannot be sent to a labor reform facility for execution, may also be supervised by a detention center. The tasks of the detention center are to carry out armed guards on detainees and prisoners in accordance with national laws to ensure safety; to educate the prisoners; to manage the life and health of the prisoners; to ensure the smooth progress of investigation, prosecution and trial work. In order to meet the needs of the new situation, improve the technology prevention capabilities of detention centers, strengthen the technical management level of detention centers, promote the construction of digital detention centers, promote the harmonious and stable development of detention centers, and continuously improve the modernization level of detention centers, it is necessary to scientifically and effectively control and prevent cell phone signals in detention centers. , to eliminate the security risks caused by illegal use of mobile phones. Scrambling Noise On Cell Phone Be the first choice of the detention center.
The host frequency output is inaccurate, the frequency drifts, the bandwidth is too wide, the power is wasted, and the base station is interfered; the simple sweeping power suppression method has low shielding efficiency, and the radiation is large; the power is falsely marked and exaggerated, and the nominal power loses its reference. Value; power is the foundation, technology is the shutdown. It is better to find good methods and techniques to fight for power; there is a certain transmitted signal strength outside the directional angle of the directional antenna, but it is much lower than the main lobe and not completely directional; the reflection of buildings will still cause external interference; the frequency of the host Drift seriously affects the base station and causes external interference; TD full-time shielding interference must exist. High power Scrambling Noise On Cell Phone Equipment radiation is large, low power radiation is small. High-power uses outdoor antennas, which have a long operating distance, large shielding coverage, and evenly shielded signals, but radiate very little; if low-power cell phone jammer devices do not use multiple antennas for long-distance shielding, but are centrally arranged or 5 antennas work together, Its radiation power will be greater than 10 microwatts/square centimeter, and the short-range radiation must be seriously exceeded;
