Specifications include, but are not limited to: The St. Louis County Crime Laboratory’s Digital Forensics Unit (“DFU”) is seeking proposals to install a Radio Frequency Shielded Enclosure (RF room). The RF room will be an integral framing system designed to provide a sound mechanical structure and low impedance RF joints. The proposed system should provide an attenuation of 100 dB to electric fields and plane waves from 14 KHz to 10 GHz and 50 dB to magnetic fields at 14 KHz rising to 90 dB at 200 KHz when tested in accordance with MIL-STD-285. The RF room will be used by the DFU to isolate cell phone, tablet, GPS, and other mobile electronics from receiving radio transmissions to preserve the digital evidence stored on the device.
