Practical Application Cases
- The EOD Brigade of the Special Police Detachment of the Municipal Public Security Bureau received an emergency alarm. A suspected remote control explosive device was found in the underground parking lot of a large commercial plaza in the city center. There is a large flow of people around the site, adjacent to business districts and residential areas, and there is a major risk of terrorist attacks and public safety. After the EOD personnel rushed to the scene, through preliminary investigation and technical research and judgment, they judged that the suspected explosive device is most likely to be detonated by wireless remote control, and the detonation trigger device may be common civil wireless equipment such as mobile phones and UAV remote controls. The wireless signal environment around the site is complex, and there is a very high risk of remote detonation by suspects during the EOD disposal process. The on-site headquarters immediately deployed this Police Portable Radio Frequency Jammer, completed the rapid deployment of the equipment at a safe distance, turned on the full-band jamming mode through remote control of computer software, instantly blocked all wireless signals such as mobile phones, wireless remote controls, walkie-talkies in the core disposal area of the site, completely cut off the signal link of the suspect's remote control detonation of the bomb, and created an absolutely safe electromagnetic disposal environment for EOD personnel. The EOD personnel then wore protective equipment and entered the core area, successfully completed the dismantling and harmless disposal of the explosive device. No safety accidents occurred during the whole process, and the major public safety hazard was successfully eliminated. In this disposal, the wide-band fast jamming and remote safe operation capabilities of this equipment provided core safety protection for the EOD disposal work, ensuring the absolute safety and smooth completion of the disposal operation.
- The Anti-Drug Detachment of the Municipal Public Security Bureau investigated a cross-provincial bulk drug trafficking case. The drug trafficking gang has a tight organization and clear hierarchy, and has extremely strong anti-investigation capabilities. The core members of the gang communicate in real time through encrypted walkie-talkies and multiple special mobile phones, and have set up multiple wireless early warning and monitoring devices around the drug trading dens and hiding dens. Once they find the police action, they will immediately destroy the drugs, tip off the news, and violently resist. Many previous arrest plans failed because the gang noticed them in advance, and the arrest was extremely difficult. After several months of careful investigation, the task force fully grasped the gang's organizational structure, dens distribution and activity rules, formulated a multi-point simultaneous assault arrest plan, equipped each arrest point with this Police Portable Radio Frequency Jammer, and carried out many actual combat drills. At the moment of the launch of the arrest operation, all points turned on the equipment synchronously, instantly cut off all mobile phones, walkie-talkies, WiFi, GPS positioning and other wireless signals inside and outside each drug trafficking den, completely disrupted the command and coordination system of the gang members, making them unable to tip off, destroy drugs, or organize violent resistance. The arrest police rushed into each dens synchronously, arrested 12 core members of the drug trafficking gang in one fell swoop, seized 15.6 kilograms of methamphetamine, drug making equipment and a large amount of involved funds on the spot, achieving the arrest of people and stolen goods. No casualties occurred during the whole arrest operation, and no suspect escaped. In this operation, the rapid deployment and full-band signal accurate blocking capabilities of this equipment perfectly guaranteed the tactical suddenness of the arrest operation, and provided key technical support for the successful detection of the case.
