Abstract
Cavities within structural members of a motor vehicle or other structure are used for propagation of wireless RF communication signals. The system is particularly adapted for use in structures wherein permanent, fixed transmission guides can be easily provided, and it is especially useful in motor vehicles where it 1) reduces the cost and power requirements of electronic modules using wireless communication, 2) shields the communication channel from outside electromagnetic interference, and 3) allows the propagation of emissions to be substantially restricted to desired regions away from people and electronic devices not in the intended network.
