EST-802B14 Portable bi-power use box jammer is an information
security product with completely independent intellectual property
right. It can exactly block the mobile phone signal like 2G GSM /
CDMA / DCS / PHS, 3G, 4G and WiFi, GPS / GLONASS , UHF / VHF, Radio
signal, and etc. in about 10-30 meters. When it finds the signals,
it will directly isolate it. Which is great for car use, school
classroom avoid exam cheat, oil/gas station keep in secure and
military use for security.
