TRUCE does not block mobile signals – it is actually illegal to do so. Instead, TRUCE uses management to foreground over a device screen, suppressing access to any app or function not allowed by company policy. Calls and messages are still being received by the device, but any audible or visual notifications or alerts are dismissed while in the work zone. For example, if your policy prohibits mobile phone use on the plant floor, then when your employee brings their phone to that location, all apps and functions are automatically suppressed. Once they leave the plant floor, the phone reverts to normal operation and notifications of missed calls or messages are delivered.
TRUCE can be configured to support the specifics of your company usage policy. In all cases, however, emergency and 911 calling is always available.
