I have developed a series of smart phone screen management systems, “the first to open in the domestic industry, based on the strength of long-term solutions, the technology integrates intelligent management (220V / 110V / 380V, 50Hz / 60Hz) to support control signal transmission, installation On remote control devices that use multiple devices (usually more than 10), the computer signal is interfered, and the mobile cell phone jammer can realize point control, group control, and general control. You can check and plan each plan regularly, you can automatically query, and automatically call alarm It will automatically disturb phone jammers or signs, etc. All dealers and new and old customers are welcome to consult our new product purchases, so we will never deceive customers to tell the truth about products, and help customers choose with the least money, the best quality products and services Own jammer.
“Many students with weak self-control ability can play games on their mobile phones, send text messages, and even listen to the teacher’s classroom discipline over the phone when they find the course content is boring. It will affect the quality. In the dormitory, other students want to take a break. Bright, they talk, and roommates can’t sleep, the school teacher told reporters. These “drone rifles” are easy to get stuck and usually aim at GPS first. If this doesn’t work, please launch within the typical frequency range of commercial drones 4G jammer and disconnect the controller link. Most off-the-shelf drones either interrupt the GPS or controller link, or enter the “return home” mode, or slowly float to the ground and land.
