The Cell Phone Jammer has been designed to block the cellular communication in a designated, secured area. SCL-CPJ operates in the frequency band of GSM, PCS, DCS, UMTS2100, and UMTS450 and blocks the cellular communication in NO MOBILE ZONES like jails, libraries, religious places, conferences, seminars and educational institutions etc.
The jamming system transmits adequate power radio signals to cut-off communications between cell phones and cellular base-stations. SCL-CJ is available in different models depending upon the output power.
Upon activating Cell phone jammer, all idle phones will indicate "NO SERVICE". When the cell phone jammer is turned off, all cell phones will automatically re-establish communications and provide full service.
