Kalamazoo company develops signal-blocking bags to limit phone use in schools

Faraday Defense, a company in Kalamazoo, Michigan, produces signal-blocking bags for schools to limit cell phone use. These bags, made with metal fibers, prevent devices from connecting to WiFi or cellular networks. Schools like Clark County in Nevada have adopted this technology. The bags are designed to create a distraction if students attempt to access their phones, helping maintain a focused learning environment. Faraday Defense also provides larger enclosures for government use, protecting sensitive electronic evidence from external tampering. The company plans to expand its operations by moving to a new location at Western Michigan University, where it aims to hire 15 to 18 additional employees in the next two years.
