Abstract: Provided are methods and systems for terrestrial data transmission between aircrafts and external networks connected to gates at airports. This type of data transmission is performed through an electrical power cable that includes multiple conductors interconnecting electrical components of an aircraft and a gate. Each conductor may be used to establish a separate broadband over power line (BPL) communication channel using its own frequency range that does not overlap with frequency ranges of other channels. As such, no radio frequency (RF) shielding is needed in the cable and any standard multi-conductor cable may be used. A channel management unit is used to control allocation of data domains among different communication channels depending on characteristics of the data domains, characteristics of the channels, and other factors. For example, one channel may be designated for secure data transfer of specific data domains, such as aircraft control data.

Abstract: A system and method for communicating audio or video information using inductive magnetic coupling between first and second adjacent seats on a mobile platform. A transceiver at the first seat receives signals from an in-flight entertainment (IFE) system. The signals are passed to a transmitter subsystem that generates low power inductive magnetic energy which is received by a receiver subsystem located on the second seat. The energy is converted to electrical signals for generating an output signal to an audio jack associated with a personal control unit (PCU) at the second seat. The audio content can then be used at the second seat together with video content displayed on a video display unit at the first seat, without affecting the synchronization of the audio signals and the video signals.

Abstract: A system and method for communicating audio or video information using inductive magnetic coupling between first and second adjacent seats on a mobile platform. A transceiver is located on the first seat and receives signals from an in-flight entertainment (IFE) system on the mobile platform. The transceiver passes the data on to a transmitter subsystem that generates low power inductive magnetic energy which is received by a receiver subsystem located on the second seat. The low power inductive magnetic energy is converted to electrical signals at the second seat and the information is output to a receiver unit of the receiver subsystem on the second seat.

Abstract: During a system reconfiguration, a selected column or column of wireless units, such as associated with airplane seats, are powered up. The first unit in the column detects a ground and begins a wireless identification process with an access point which allows the system to determine a corresponding physical location for each node's logical address. The first unit then closes a switch, which connects the ground to the next unit. As the next unit detects the ground on the line, such as a token line, the second unit communicates with the AP. This process continues sequentially down the column until the last unit is assigned a physical location/address. The next column of units can then be powered up and identified.
