Abstract
Embodiments are directed to systems and methods for utilizing aircraft cockpit and cabin lighting to provide both power and data transmission to occupants. Data and power may be transmitted on non-visible and/or visible spectrums. The visible light may be used independently for aircraft illumination. Data for the cockpit allows for quick upload and download of flight planning and maintenance data to an electronic flight bag. The electronic flight bag may also be able to receive power from cockpit and cabin lighting during flight.
Claims20
A system for providing light communication (LC) for an aircraft, comprising:
- one or more LC transmitters, each LC transmitter configured to broadcast light of a particular frequency or frequency band within a respective defined region of an avionics or maintenance compartment of the aircraft to establish an attocell in the respective defined region of the avionics or maintenance compartment;
- a portable device comprising an LC receiver configured to receive light broadcast by at least one of the LC transmitters at one or more particular frequency or frequency bands;
- and
- an interface to an aircraft data network in electronic communication with aircraft systems monitoring and to the LC transmitters and therethrough to the portable device when the portable device is disposed in a particular defined region of the avionics or maintenance compartment.
A system for providing light communication (LC) for an aircraft, comprising:
- one or more LC transmitters, each LC transmitter configured to broadcast light of a particular frequency or frequency band at, but not inside, a respective avionics or maintenance compartment of the aircraft to establish an attocell at, but not inside, the respective avionics or maintenance compartment;
- a portable device comprising an LC receiver configured to receive light broadcast by at least one of the LC transmitters at one or more particular frequency or frequency bands;
- and
- an interface to an aircraft data network in electronic communication with aircraft systems monitoring and to the LC transmitters and therethrough to the portable device when the portable device is disposed in a particular defined region at, but not inside, the avionics or maintenance compartment.
