Choosing a Faraday Cabinet for the Lab
Capacity, attenuation rating, charging integration and audit features — what to specify when buying lab storage.
Quick Answer
Specify a minimum attenuation across LTE, 5G NR sub-6, Wi-Fi 2.4/5/6 GHz, BT and GNSS bands. Independent test data should be available from the supplier.
Attenuation and Frequency Coverage
Specify a minimum attenuation across LTE, 5G NR sub-6, Wi-Fi 2.4/5/6 GHz, BT and GNSS bands. Independent test data should be available from the supplier.
Charging While Isolated
Devices held for extended periods need power. Internal pass-through USB or mains supply must not compromise the cabinet's RF integrity — look for filtered feedthroughs.
Capacity and Layout
Match drawer count and layout to your throughput. A custody suite with 50 daily seizures has different requirements to a national-scale lab.
Access Control and Audit
Logged access — RFID, PIN or biometric — combined with internal CCTV creates a defensible custody record for everything the cabinet holds.
