The mobile phone jammer transmits low power radio signals to cut off communications between mobile phones and mobile phone stations. SK-3 mobile phone jammer blocks all bands from 800MHz to 2400MHz (Such as GSM, CDMA, DCS, PHS, 3G) within around 20 meters completely. The mobile phone jammer does not interfere with any communications other than mobile phones within the defined regulated zone. Upon activating a mobile phone jammer, all idle phones will indicate "Not in service zoon." Incoming calls are blocked as if the mobile phone were off. The new generation mobile phone jammer is now a necessity for law enforcement and the military to interrupt communications by criminals and terrorists, and also for accomplishing a more cultured society.
