Cellular signal blocking device , signal transduction inhibitor

IntroductionA portable wireless signal jammer is an information security product with a completely independent intellectual property right. It can exactly block the wireless signals like wireless network, Bluetooth, wireless transmission, etc. and tracking signal like car positioning, mobile phone positioning, google network positioning, etc. in about 1-20 meters. When it finds the signals, it will directly isolate it. Features1, effective prevention by GPS satellite positioning tracking, to protect your whereabouts of privacy and confidential information2, while effectively shielding CDMA / GSM / DCS / PHS / 3G / 4G and other mobile phone signals3, small size, lightweight, large coverage, easy to carry
