A Bluetooth zone control system comprising: a first Bluetooth device configured to provide a first Bluetooth signal, a location of the first Bluetooth device corresponding to a location of a first machine; and an operator control unit including a second Bluetooth device; and a third Bluetooth device configured to provide a second Bluetooth signal, a location of the third Bluetooth device corresponding to a location of a second machine; wherein the second Bluetooth device of the operator control unit is configured to detect the first Bluetooth signal and the second Bluetooth signal, the operator control unit configured to: control movement of the first machine via an RF signal protocol, a WiFi wireless signal protocol or a TCP/IP protocol, to perform a work task based on first authorization rights when the second Bluetooth device detects the first Bluetooth signal at or above a signal threshold; control the first machine via the RF signal protocol, the WiFi wireless signal protocol or the TCP/IP protocol, based on second authorization rights when the second Bluetooth device does not detect the first Bluetooth signal at or above the signal threshold; control movement of the second machine based on third authorization rights when the second Bluetooth device detects the second Bluetooth signal at or above the signal threshold; and control the second machine based on fourth authorization rights when the second Bluetooth device does not detect the second Bluetooth signal at or above the signal threshold; wherein the first authorization rights include allowing control of movement of the first machine to perform the work task using the operator control unit, the second authorization rights include at least turning off the first machine using the operator control unit, and the first machine comprises one of a manufacturing equipment, an assembly line equipment, a press and stamping machine, a crane, a hoist, a rail maintenance of way machine, a packaging equipment, and a testing equipment. a first Bluetooth device configured to provide a first Bluetooth signal, a location of the first Bluetooth device corresponding to a location of a first machine;
