Communication Device, Article of Personal Protective Equipment and Method of Communication

A communication device for an article of personal protective equipment, the communication device comprising:

• a plurality of communication circuits corresponding to a plurality of modulation schemes and a plurality of communication channels, the plurality of communication channels comprising different bandwidths from each other, wherein each communication circuit is configured to modulate a signal using a corresponding modulation scheme from the plurality of modulation schemes for transmission over a corresponding communication channel from the plurality of communication channels;
• a switching circuit configured to selectively switch between the plurality of communication circuits, wherein the switching circuit is configured to receive an input signal;
• and
• a controller communicably coupled with the plurality of communication circuits and the switching circuit, wherein the controller is configured to:
• determine a criticality level of the input signal;
• and
• control the switching circuit to switch between the plurality of communication circuits and select one communication circuit from the plurality of communication circuits based on the criticality level of the input signal, such that the one communication circuit receives the input signal and modulates the input signal using the corresponding modulation scheme for transmission over the corresponding communication channel.
