Main technical indices of cell phone jammer: effective shielding diameter is 40m or so (dependent on strength of indoor cell phone signal); shielding signal band width: 860MHZ―885MHZ；930MHZ―960MHZZ；1800MHZ―1990MHZ; ambient temperature: -20℃~+55℃; relative humidity: 30%~95%; power supply voltage: input, AC 100V~240V; volume: 210mm×135mm×45mm.
Main functions of cell phone jammer: it can effectively shield such cell phone signals as GSM900、DCS1800、PCS1900、CDMA and PHS; it only shields cell phone signal and not influence normal work of other electronic equipments; it can be used in any area over 200m away from the base station; it can stably work for a long time after switching on; the slow-start circuit design can avoid sparking phenomenon caused the mechanical switch.
The cell phone jammer is the most convenient for use with high cost performance in the current market.
