ECM712 Portable Faraday Cage Unit for Forensic Analysis Applications

The ECM712 is a small portable unit designed to be used for the safe forensic analysis of cellular devices such as phones or tablets.

Twelve independent countermeasure transmitters are connected to a special near field antenna (NFA) to provide a localised non polarised isolation field evenly above the lid area in effect creating a virtual hemispherical Faraday Cage.

This allows the analysis of both phones and tablets without the fear of remote interference over cellular networks or nearby WIFI sources. The characteristics of the NFA cause the isolation signals to reduce rapidly with distance so beyond the stated bubble sizes there is no interference with adjacent devices.

The transmit power of each transmitter can be individually reduced to suit the operational environment which in turn will reduce the exclusion zone area. Once the desired the parameters have been set, they are stored within each unit. The user now simply powers up the unit and all transmitters will function according to the options that have been set.

Operational modes and functions

The main control panel software allows the user to select which transmitters are active and the power level attributed to each transmitter. Full power allows the unit to be used outside in new locations where the strength of the mobile signals are unknown. In lab environments the power can be reduced, especially open office areas, to prevent interference with nearby staff who may need to use their mobile phones.

When the transmitters are set to max the Faraday bubble extends approximately 5 metres from the antenna. This setting can also provide a cellular and WIFI isolation area to small meeting rooms without impacting other nearby rooms.

Another application, allows a technician to define and set the most appropriate RF values for the Lo, Med, and Hi settings antenna
