Patent ID: 8666254

Claim:
A method comprising: receiving, from at least one of a first plurality of wireless optical transceivers at first redundant locations within an interior cabin of a vehicle, a first distributed optical signal by a set of wireless optical transceivers of a second plurality of wireless optical transceivers at second redundant locations within the interior cabin of the vehicle at a first wavelength via open line-of-sight transmissions, wherein the second plurality of wireless optical transceivers is coupled to a signal comparator that is onboard the vehicle, and wherein the signal comparator is coupled to a receiving system that is onboard the vehicle; generating, by each wireless optical transceiver of the set of wireless optical transceivers that received the first distributed optical signal, output corresponding to the first distributed optical signal; sending, by each wireless optical transceiver of the set of wireless optical transceivers that received the first distributed optical signal, the generated output to the signal comparator; determining, by the signal comparator, which of the wireless optical transceivers of the set of wireless optical transceivers that received the first distributed optical signal received a strongest signal; and presenting the generated output corresponding to the strongest signal to the receiving system.
