Smart Phone is a Target
Smart phone is a “basic” device for us, we carry this
“small PC” everywhere.
From the Edward Snowden case, mobile phone can be a spy
tool and help to transmit data to others.
The NEW 4G Detector is not only can detect mobile phone signal but also can
sweep the GSM bug and 3G bug.
Why use a built-in antenna hand held detector instead of a directional antenna ?
- Unless
the user knows where the target is, a directional antenna will not provide
capability to catch the very transmission.
- The device is designed to catch signal bursts from all directions because the
user would not be able to predict where the transmission will come from in
advance.
- Unless
a rotary directional antenna (like radar antenna) is used, directional
antenna is disadvantageous. A detector using rotary directional antenna is
in different category of business.
- Unless
the user is in an open space, directional antenna can not accurately pin
point the target due to multiple reflections from the surrounding building
structure.
- Reducing the sensitivity and gradually zero in to the target is the best practice for small area (less than 50 meters radius) application.
