Strong electromagnetic environment must be avoided to ensure the barrier effect and long-term stable operation. When not in use, please turn off the power in time. Waterproofing is very important when using it outdoors. Do not disassemble the antenna when deterring, so as not to affect the shielding effect. Actual shielding range may vary depending on the location of use. The effective blocking area is the circular area centered on the sword. For Cell Phone Blocker Mini Project Ppt , the effective distance (30-40 meters) generally refers to the indoor distance. The shielding distance of outdoor areas can be up to several hundred meters. The effective range of the interfering device is related to environmental conditions such as the distance from the base station and the installation location. These factors need to be carefully considered so as not to affect the shielding effect. The strength of the electromagnetic signal emitted by the cell phone jammer is very weak.
A few days ago, the Linhe District Public Security Bureau received a report from the Bayannaoer Branch of China Mobile and found an abnormal signal near the No. 1 group in Yuejin Village, Shuanghe Town, affecting the normal use of the network by the surrounding residents. Police from Tongke and Shuanghe town police stations rushed to the scene. After using the wireless detection equipment to locate, the strongest interference signal was the warehouse of a group of people in Yuejin Village. The police immediately contacted Wang San, the tenant of the warehouse. After Wang San opened the warehouse door, the police seized Cell Phone Blocker Mini Project Ppt , two of which were working. The police summoned Wang San to the investigation center of the District Public Security Bureau in accordance with the law. After investigation, Wang San was engaged in second-hand car trading and mortgage loan business. Since some car owners have installed GPS trackers on their mortgaged vehicles, in order to shield the GPS signals of the mortgaged vehicles, Wangsan purchased a mobile phone signal blocker and installed it in the warehouse. Subsequently, the police visited the surrounding residents, and everyone agreed that the wireless signal was poor recently and the Internet could not be accessed normally.
