Once the silence tag detects a pedestrian tag within the preconfigured range, any pedestrian tag will not be acted by surrounding devices and eventually become silent. Then, the pedestrian tag will re-alert once leaving the zone. The safety zone feature is widely used in small ones inside the warehouse and employees’ lounges. Figure 1.
