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 jammering brand covers many kinds of frequency brand. GSH mobile phone jammers block all mobile phonesingals,suchas:

GSM, CDMA, PHS.And can also block Little Smart Wireless Cityphone signal, SCDMA signal. GSH 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 mobilephones 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: GSH mobile phone jammers have high reliability, can work continuously in all places, if they are used outdoors, can use a wood case with a hool on the side to fix it to prevent water.

5 .Environment protection equipment, no harm to human being: GSH 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 .
