DM-1301 type of Cellular Phone Jammer adopts the latest electronic interference technology. It can cut off connection between the wireless cell phone and mobile communication base station so that the cell phone can not make or answer calls in the specified range. And then purpose of shielding cell phone signal can be achieved and the above problems can be avoided. The mobile phone jammer can block the following cell phone systems: GSM of China Mobile; GSM and CDMA of China Unicom; PHS of China Telecom.
Main functions of cell phone jammer: it can shield such wireless communication tools as GSM, CDMA cell phone and PHS.
Main characteristics of cell phone jammer: 1. the effective shielding rang is 10-30m (dependent on distance of the base station); 2. it is environmentally green and does no harm to human body; 3. it will not influence the cell phone signal outside the working range; 4. it is easy and convenient to install and it can be used after inserting the plug.
Applicable range of cell phone jammer: it is applicable to the meeting room, examination room, concert hall, cinema, library, court ad church and so on.
Performance indices of cell phone jammer: 1. shielding frequency: 869-894MHz(CDMA)?935-960MHz(GSM)?1805- 1880MHz(GSM)?1900-1920MHz(PHS); 2. shielding object: GSM and CDMA cell phone and PHS; 3. shielding radius: 10-30m (dependent on distance of the base station and indoor field strength); 4. output power: dual channels of 2W; 5. power supply voltage: AC 220V; 6. ambient temp.: 0?-55?
