Claim Text:
1. A method for providing information by optimizing a data rate to a vehicle over a single three-phase power line utilized to provide power to the vehicle, said method comprising: assigning three separate frequency bands to three respective conductors extending between a ground power system and the vehicle, the three respective conductors forming the three-phase power line; generating carrier signals in the three separate frequency bands, wherein the three separate frequency bands are between about 2 MHz and about 80 MHz; modulating various data onto the three carrier signals to generate three transmission signals for sending the various data from the ground power system to the vehicle at frequencies within respective ones of the three separate frequency bands, wherein the frequencies for each of the three separate frequency bands do not overlap one another; switching the three transmission signals onto respective conductors of the three-phase power line; monitoring an impedance of each conductor; adjusting the frequencies for each conductor based on changes in the monitored impedance; demodulating the various data within the vehicle; providing the various data to one or more vehicle systems.
