In this digital era of radio waves, electromagnetic signals are like nerve veins running through the skin of the city, carrying messages from every corner. Wireless networks, cell phone calls, radio and television, all of which are indispensable to the survival of the city's lifeblood.

 
As a storage center for cash and valuables for banks and other financial institutions, vault security has always been a top priority. Traditional means of anti-theft such as physical protection and monitoring systems have been insufficient to give, now the banking industry has also begun to introduce Jammer (wireless signal shielding) this cutting-edge technology for the vault cash anti-theft work to add technological tools.

In recent years, with the rapid development of drones, model airplanes and other civil aircraft, the threat of jamming against their flight safety has become increasingly serious, and jammer may cause the aircraft to crash out of control by transmitting jamming signals, resulting in casualties and property losses. Therefore, timely and effective detection and localization of Jammer signals are essential to ensure the flight safety of model aircrafts.
Characterization of Jammer signals
Analyze the frequency, bandwidth, power and modulation of different types of signal blocker device signals to establish a Jammer signal feature library, which lays the foundation for detection and identification.
Energy monitoring and frequency sweep detection
Deploying energy monitoring and frequency sweeping detectors in the operating frequency band of the aircraft to continuously monitor the spectral environment, and once abnormal energy signs are detected, the signal capture judgment and analysis will be triggered.
Time-frequency domain feature extraction and matching
Pre-process the captured abnormal signals, extract their time-frequency domain feature parameters, and match them with Jammer signal feature library to identify whether they belong to 5G jammer signals or not.
Heading/ranging/frequency system
For the Jammer signal, configure the position detection subsystems such as heading solving system, ranging system, frequency measurement system, etc., to realize the positioning of the Jammer transmitter.
Navigation/radar signal assisted localization
Combined with the vehicle's own navigation system, radar information and other data, the position of the Jammer launch source is composite solved to improve the positioning accuracy.
Multi-point station cooperative network localization
Deploying multiple decentralized monitoring stations to perform cross-station location network positioning through time/frequency difference measurements and signal arrival angle measurements.
Coordinate data upload and indication
Upload the precise coordinates of the audio recording jammer transmitting source to the command terminal via wireless link, and visually indicate the Jammer signal source location on the electronic map.
Quick Avoidance and Suppression Strategy
After receiving the Jammer coordinates, the aircraft will quickly avoid the jamming source according to the preset strategy, or cooperate with ground units to suppress the jamming source.
Jammer signal detection and localization is a highly automated and networked process, which requires strong algorithmic support and system engineering capability. Among them, bluetooth scrambler signal modeling and feature parameter extraction are especially critical. With the development of miniaturization and low-power technology, this capability can be integrated into the vehicle to form an autonomous anti-jamming protection system. It is of great significance to protect the safety of unmanned aerial vehicles such as aeromodels.

 
With the continuous popularization and application of UAV technology in the civil field, the issue of air safety is getting more and more attention. If a UAV is controlled by hackers or used maliciously, it will bring serious security risks. Against this background, wifi signal jammer, as an effective radio countermeasure, plays an important role in ensuring the safe operation of commercial UAVs. Let's explore the specific impacts and applications of Jammer in this area.

 
At present, communication jamming technology is closely integrated with artificial intelligence, cognitive radio, MIMO beam fusion and other emerging technologies, towards the rapid development of intelligent, accurate and integrated direction, in order to improve the jamming efficiency and accuracy.

With the rapid development of drone technology, its use in various types of illegal activities is increasing, posing a serious threat to public safety. To address this challenge, smart signal blocker are rapidly emerging as an emerging technology and an important means of protecting critical infrastructure and public safety. Smart jammers incorporate Artificial Intelligence (AI) technology, which greatly improves their protection capability and response efficiency.

With the rapid development of drone technology, its application in various industries has become increasingly widespread. However, the popularity of drones has also brought about many security risks, especially trespassing over sensitive areas such as airports, military bases and government facilities. To address these challenges, signal jammer play a vital role in drone protection as an effective protection tool.
