Claim:
A method comprising: encoding first safety data within media access information in a message using a first processor, the message including the media access information and application information, the first safety data generated by a first switch that is controlled by an operator control unit; encoding second safety data within application information of the message using a second processor, the second safety data being redundant of the first safety data and generated by a second switch that is controlled by the operator control unit; transmitting the message over a wireless communications link; receiving the message and extracting the first safety data at a first receiver; receiving the message and extracting the second safety data at a second receiver; communicating the first safety data over a first data path to a first device that is responsive to the first receiver for responding to the first safety data; and communicating the second safety data over a parallel, second data path to a second device that is responsive to the second receiver for responding to the second safety data.
