TDD Digital Jammer

Product Introduction

4G/5G TDD digital jammer is a jammer specially designed to shi the downlink of TDD (Time Division Duplex) system.

TDD digital jammers emit radio waves of the same frequency as mobile phones and wireless communication devices, forming an electronic interference that prevents mobile phones and other devices from receiving and sending signals normally. The key is to accurately identify and interfere with downlink signals in a specific frequency band and time. Ensure that the uplink signal works normally without interfering with the communication base station. Specifically, the TDD digital jammer will first determine the frequency band range used by the TDD system, and then synchronize with the time slot of the TDD system to ensure that downlink interference is only performed within the time slot of the downlink. In this way, the user equipment cannot receive downlink data from the base station, thereby achieving the purpose of signal shielding.

The frequency band and time synchronization of the TDD digital jammer system are accurate to avoid interference with normal communications. TDD digital jammers use high-precision hardware components, such as high-precision clocks and synchronization circuits, to ensure the accuracy of synchronization. These hardware components can provide stable clock signals and precise synchronization control to ensure that the jammer is accurately synchronized with the TDD system.

When dealing with the frequency band and time adjustments of the TDD system, the TDD digital jammer needs to adopt comprehensive response strategies such as real-time monitoring and identification, frequency band database updates, dynamic adjustment capabilities, time slot synchronization technology, rapid response mechanisms, and algorithm optimization. These measures work together to ensure that the jammer can maintain a stable and accurate interference effect when facing changes in the TDD system.

Features

1. Time synchronization: The signal jammer needs to be synchronized with the time slot of the TDD system to ensure that interference only occurs in the downlink time slot without affecting the uplink.

2. Signal identification: The spectrum analysis technology is used to monitor the signal in real time to distinguish the uplink and downlink signal characteristics. This is a key step in achieving precise interference.

3. Interference generation: After identifying the time of the downlink, the signal jammer sends out an interference signal in the corresponding frequency band. The interference signal should be strong enough to cover the downlink signal, thereby blocking the user equipment from receiving the downlink data of the base station.

4. Dynamic adjustment: The time slot of the TDD system may be very short, and the TDD digital jammer needs to have the ability to respond quickly and dynamically adjust as well as high-precision synchronization capabilities to ensure the accuracy and effectiveness of the interference. .

5. Real-time monitoring: The time slot of the TDD system changes, and quickly adjusts its own transmission timing and frequency as needed.
