RFD-03

GSM CDMA 3G Mobile Phone Signal Detection System

Description
RFD-03 GSM CDMA 3G Mobile Phone Signal Detection System is especially designed for immediately detecting signals of any mobile  phone system within its effective range, then send out alarm signals or voice to the monitoring staff. RFD-03 GSM CDMA 3G Mobile Phone Signal Detection System can also link with mobile phone  jamming  device through its own AC power socket and prevent concerns over the always-on broadcasting of jamming electro-magnetic waves. The actual operation is started by conducting detection within RFD-03’s range first. RFD-03 Multi-Tasking GSM CDMA 3G Mobile Phone Signal Detection System will not activate the jamming device if there is no transmission signal around. Once there is any mobile phone signal, RFD-03 Multi-Tasking  GSM CDMA 3G Mobile Phone Signal Detection System will immediately make the jamming device activate the jamming broadcasting. The whole operation and response do not exceed 20 ms time.

Features

• RFD-03 Multi-Tasking GSM CDMA 3G Mobile Phone Signal Detection System simultaneously detects four band (GSM/DCS/CDMA/3G) transmission signals.
• Each band is designed with individual detection circuit for high sensitivity and consistency.
• Broad band Log Amplifier design.
• Active striping filter designed for high selectivity and low false alarm.
• RFD-03 can look through the mobile phone signal and can automatically activate the jamming device to break the communication when needed. Therefore, RFD-03 can eliminate the health concern of always-on jamming radio wave to human body.
• RFD-03 has the RS-485 data communication port to send operational status and receive control signal.
• LED Indicators: system activity and each band link status indicators.
