Abstract

A system and method for updating and maintaining an onboard entertainment server on an aircraft includes a gate LiFi access point positioned in a gate area of an airport, the gate LiFi access point having a removable server. An aircraft LiFi receiver is positioned in the aircraft, the aircraft LiFi receiver and the removable server capable of line-of-sight transmission of updated data and a content loader receives the updated data in the onboard entertainment server.

Claims (18)

1. A system for updating and maintaining an onboard entertainment server on an aircraft, the system comprising:

a gate LiFi access point positioned in a gate area of an airport, the gate LiFi access point having a removable server, wherein the gate LiFi access point is integrated with a ticket reader configured to scan and confirm passengers at a terminal gate;

an aircraft LiFi receiver positioned in the aircraft, the aircraft LiFi receiver and the removable server capable of line-of-sight transmission of updated data when the removable server is removed from the gate LiFi access point; and

a content loader to receive the updated data in the onboard entertainment server.

2. The system of claim 1 wherein the gate LiFi access point includes an optical transmitter comprising one or more light emitting diodes.

3. The system of claim 1 wherein the updated data includes data selected by a passenger on the aircraft.

4. The system of claim 3 wherein the data is selected by the passenger within an airline application.

5. A method for updating and maintaining an onboard entertainment server on an aircraft, the method comprising:

positioning a gate LiFi access point in a gate area of an airport, the gate LiFi access point having a removable server;

scanning a passenger ticket using the gate LiFi access point;

updating data in the removable server;

removing the removable server from the gate LiFi access point;

positioning the removable server within a line-of-sight of an aircraft LiFi receiver positioned in the aircraft to transmit updated data; and

updating the onboard entertainment server of the aircraft with the updated data.

6. The method of claim 5 further comprising permitting a passenger to select at least a portion of the updated data.

7. The method of claim 5 further comprising positioning a content loader between the aircraft LiFi receiver and the onboard entertainment server.

8. The method of claim 5 further comprising:
