Functions of a Cell Phone Signal Jammer:
- It could block any mobile phone signal from coming in. While you are operating businesses you recognize that the individuals are heading for coming in as well as gabbing on their phone the full time
- The cell phone signal blocker could check people from being troubled by the phone
- Cell phone signal blocker is originally developed for law enforcement and the military to interrupt communications by criminals and terrorists
- Corporations use jammers to stop corporate espionage by blocking voice transmissions and photo transmissions from camera phones

How a Cell Phone Signal Jammer 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 CDMA, DCS, GSM, PCS, GPRS and WCDMA systems
