PROBLEM TO BE SOLVED: To provide methods and systems for terrestrial data transmission between aircrafts and external networks.SOLUTION: When an aircraft 100a, b is parked at a gate 120a, b, the aircraft is connected to and powered by an electrical cable 122a, b. This cable is also used for wired data transmission between the aircraft and the gate using broadband-over-power-line (BPL) technology. The gate and the aircraft are each equipped with a broadband-over-power-line module 126. The aircraft may include other communication modules, such as a Wi-Fi module, a cellular module, and/or an Ethernet module. These other modules can be also used for data transmission. A communication link manager may be used to select one or more communication modules depending on availability of communication links, costs, speed, and other parameters. |
