Exciter-excitation system and methods for communications

A system for communicating a information from a first location within a vehicle to a second location within or very near to the vehicle, wherein the vehicle has a conductive metallic structure defining one or more major compartments, the system comprising:

• an exciter unit including a first communication equipment and an exciter device that is conductively connected to the metallic structure of the vehicle;
• a remote unit including a second communication equipment having a probe that is not conductively connected to the metallic structure of the vehicle;
• said first communication equipment suitable to accept the information at the first location and modulate a signal with the information, wherein said signal has a carrier frequency that is selected to be either below cut-off for evanescent electromagnetic fields or above cut-off for propagating electromagnetic fields;
• said exciter device suitable to receive said signal from said first communication equipment and conductively inject said signal as a current into the metallic structure of the vehicle such that an electromagnetic field is produced;
• and
• said second communication equipment suitable to couplingly receive said electromagnetic field from the metallic structure of the vehicle via said probe, demodulate the information from said electromagnetic field, and provide the information at the second location, thereby providing the ability to communicate the information from said first location to said second location in a wireless manner.
