Have you ever been interrupted by the uproarious cell phone ringtone when you were making a speech? Are you bothered by students'cheating with high-tech communications equipment in examinations? If you do have this unpleasant experience, we would like to introduce you this signal blocker jammer. This cell phone signal blocker is a high-tech product which is adopted the advanced technology and meticulously produced according to the practical situation of domestic and overseas mobile communication. The cell phone signal blocker can create magnetic shield while in working process. Cell phone signal within 10M will be arbitrarily blocked. Other electronic equipment won't be interfered. This cell phone signal blocker is suitable for many occasions, such as cinema, theatre, library, concert, recording room and so on. The cellular phone jammer also has an excellent performance on other locations where secret and quiet are requested absolutely.

- Slow start us design of circuit .These elements can maintain the s table operation condition with high integration.
How a Cell Phone Signal blocker Works
A jamming device transmits on the same radio frequencies as the cell phone, disrupts the communication between the phone and cell phone base station in the cell phone tower. It's a called a denial-of-service attack
Other jamming devices overpower the cell phone by transmitting a signal on the same frequency and at high enough power that the two signals collide and cancel each other out
Blocker will disrupt a signal regardless of the type of cell phone system in use. They are effective against AMPS, CDMA, TDMA, GSM, PCS, DCS, iDEN, and Nextel systems
Will not affect the other electronic devices
Small and lightweight design that is easy to hide and carry
Can be charged by AC adapter or car charger
Please don’t put the jammer in high voltage and high magnetism locations
