mobile/cell phone jammer

Special phone signal blockers (the paperback edition),

Along with the rapid development of modern communication technology has been widely used in mobile phone and mobile telephone communications in popularization of convenience to people, but also give communications security and secrecy work puts forward new challenges. In recent years, China has occurred in the use of mobile phones, leak, examination, medical accidents, gas cheating as major accident, its explosion has caused serious damage degree and the leaders are highly valued.
A mobile phone signal. JN101 blockers (the paperback edition) according to the demand of the market by the special way of advanced technology, in the work can be formed within the scope of magnetic shielding, mobile phone cannot hit, access, so as to achieve the purpose of mobile phone mandatory disabled. This mobile phone signal blockers, thoroughly solved the phone with all kinds of hazard, make people both enjoy the high-tech brings to the swift and convenient and the environment around, not only for mobile telephone communications signals, without interference in other electronic equipments.

Ii. The mobile phone signal blockers

4. The mobile phone use blockers signal
1 choice to cut off the phone signal, will cut the area is placed on the table or wall.
2 after the installation is complete, cut off power supply device connected to turn on the power switch.
3 after the device connected, press the power switch off work device. This site is open all the search network state, mobile base signal loss. Lord called all cannot build communication.
The principle of mobile phone signal blockers
Five, the mobile communication principle:
The principle of work is as follows: mobile phone in a certain frequency range, mobile phones and radio stations to connect, modulation and complete baud rate, data and voice transmission.

Six, mobile phone signal blockers principles: the principle of mobile communications, the process of working on the screen with a certain speed to the low frequency channel was to high-end scanning. The scanning velocity can receive message signal in mobile phone, formed in garbled interference can detect the normal data from a base, establish connection with base under-voltage cannot. Mobile phone network performance for the search, no signal, service system etc.

Seven, basic function: 1) slow start function: mobile phone jammers blockers (in after electrify source, work in four seconds from zero to stability. 2) shielding function: 35 seconds after starting, the range of mobile phones was shielding.

The basic properties: launch frequency range: 1) 8.6 + 0-5-960 + 5-0 MHz. 2) 18 + 0-20-1990 + 20-20 MHz) transmit power: 1) 35 ± 2dbm. 32 2dbm ± 2). Environmental temperature: - 20-55 ° c + + : 35-85% of relative humidity control scope: 0-15 action frequency CDMA800: GSM900, DCS1800, PCS1900, and PHS.
