Performance and parameter of mobile phone jammer
1.Easy to operate, easy to install: To start working, only need to install antennas correctly, and switch on power supply.
2.Frequency jamming brand covers many kinds of frequency brand. NBT mobile phone jammers block all mobile phone singals,such as:GSM, CDMA, PHS.And can also block Little Smart Wireless cell phone signal, SCDMA signal. NBT mobile phone jammers only block downlink frequency from BTS, does not block uplink frequency from BTS, has no affection to other BTS, this is also what other brand of jammers fail to do.
3.No harm to mobile phones: mobile phones can not send out or receive signals when the mobile phones are in jamming area.after get out of jamming area,mobile phones will automatically reestablish communications and provide full service.
4.Can work automatically, doesn't need human being to maintain: NBT mobile phone jammers have high reliability, can work continuously in all places, if they are used outdoors, can use a wood case with a heels on the side to fix it to prevent water.
5.Environment protection equipment, no harm to human being: NBT mobile phone jammer is low powered, consumes little electrical energy. No affection to human being and other electrical equipment (interphones, wireless microphones, Wireless Network equipment, for example.) Because they are not working in the same frequency.
6.React rapidly: react rapidly to different kinds of mobile phones. Block all kinds of mobile phone signals about ten seconds after switched on. And reestablish communications and provide full service about several seconds after switched off .
