Knowledge of Cellphone Jammer
A mobile phone jammer transmits low-powered radio signals to cut off communications between cell phones and cell base stations. It does not interfere with any communications other than cellular phones within the defined regulated zone. Upon activating a phone jammer, all idle phones will indicate “NO NETWORK. ” Incoming calls are blocked as if the cellular hand phone were off. When the phone jammer is turned off, all cell hand phones will automatically re-establish communications and provide full service. China Manufacturer Specifications
