The Linghang Xingan LHXA-SC is a self-developed confidentiality product designed to store and shield mobile phones. It is suitable for classified areas such as government agencies, military meeting rooms, and examination sites. The device uses physical shielding technology to prevent signal leakage without radiation or interference.
The cabinet utilizes high-quality electrolytic steel plates with argon arc welding to ensure electromagnetic continuity. Signal blocking works by absorbing microwave signals (2G/3G/4G/WiFi) through the metal shell, converting them into heat loss so they cannot reach the phone's receiver module.
