Handheld mobile phone blockers, used by personnel in the protective cell phone remote-controlled bomb, which can effectively shield the interference generated by mobile phones and the dedicated frequency radio waves, the phone communication signals aborted (OFF hearing), in order to safeguard the safety of personnel.
Each frequency required to follow the practical tasks, adjust transmit power on or off.
When you start the device should also generate individual frequency blocking action.
Interference way: mining shield blocking of omnidirectional
Blocking system shadowing distance: different diameters 3 to 5 meters, depending on the actual circumstances at different distances (distance affect the strength of the base station)
Battery working time: fully charged lithium battery can support from 2 hours
Shield blocking frequency must cover the following systems with transmit power:
790MHz ~ 880MHzï¼š1 watt. (4G LTE)
920MHz ~ 965MHzï¼š1 watt. (4G LTE - GSM)
1800MHz ~ 1990MHzï¼š1 watt. (4G LTE â€“ CDMA,DCS,GSM)
2110MHz ~ 2170MHzï¼š1 watt. (3G - WCDMA)
2400MHz ~ 2500MHzï¼š1 watt. (WiFi 2.4G)
2620MHz ~ 2690MHzï¼š1 watt. (4G LTE - WiMAX)
GPS L1 1575.42MHzï¼š1 watt.
Remote control 433MHzï¼š1 watt. (UHF)
