  • Patent number: 9692500
    Abstract: A method and apparatus for exchanging information between a source and an aircraft. In response to a request to exchange the information between the aircraft and the source, a number of aircraft is identified to send microwave signals between the source and the aircraft to form a number of identified aircraft based on a location of the aircraft and a location of the source. The number of identified aircraft is configured to send the microwave signals between the source and the aircraft to form a number of configured aircraft. The number of configured aircraft forms a mobile network. The microwave signals are sent between the source and the aircraft using the number of configured aircraft. The information is exchanged between the aircraft and the source using the microwave signals sent through the mobile network.

  • Patent number: 9673863
    Abstract: A method for providing information by optimizing the data rate to a vehicle over a three-phase power line utilized to provide power to the vehicle is described. The method includes assigning three separate frequency bands to three respective conductors extending between a ground power system and the vehicle, generating carrier signals in three separate frequency bands and modulating various data onto three carrier signals to generate three transmission signals for sending the various data from the ground power system to the vehicle at frequencies within respective ones of the three separate frequency bands. The frequencies for each of the three separate frequency bands do not overlap one another. The method also includes switching the three transmission signals onto respective conductors of the three-phase power line, demodulating the various data within the vehicle, and providing the various data to one or more vehicle systems.

  • Patent number: 9667316
    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.

  • Patent number: 9667338
    Abstract: Provided are methods and systems for multiband wireless data transmission between aircraft and ground systems. The transmission uses different wavelength ranges, each wavelength range corresponding to a different data domain and establishing a different communication channel. This wavelength differentiation provides physical separation between different data domains and, as a result, improves data security. Furthermore, a single broadband antenna is used on the exterior of the aircraft for transmitting data sets from different data domains. The single antenna configuration reduces drag and weight and improves structural integrity of the aircraft in comparison to multi-antenna configurations. Different aircraft communication modules, which are connected to different aircraft systems, handle different data domains and operate at different wavelength ranges. These modules are connected to the same antenna using a multiplexer.

  • Publication number: 20170041792
    Abstract: A shared data communications system includes a network file server and two routers, each with its own address. A first router provides wireless access to a first part of the system. A second router provides wireless access to a second part of the same, shared system via the technique known as broadband-over-power line (BPL). In the second part, a first BPL unit is carried by the proximal end of an electrical conductor for receiving and sending signals between it and distal, second BPL unit on the same electrical conductor. The use of separate routers with different addresses and a power line to transmit and receive data to confine the wireless portion of the second part of the system to a smaller area increase the physical security of wireless communications with the second part, making it less likely data communications taking place in the second part will be accessed by others.

  • Publication number: 20160330242
    Abstract: An inline ARINC data authenticity inspection module, method and computer program product are provided. In the context of a method, ARINC data that is transmitted via an ARINC bus is received into a buffer partition. The method also includes inspecting the ARINC data from the buffer partition within an inspection partition. The method further includes determining, as a result of having inspected the ARINC data within the inspection partition, whether the ARINC data is authentic. In an instance in which the ARINC data is determined to not be authentic, the method logs receipt of the ARINC data that is determined to not be authentic. However, in an instance in which the ARINC data is determined to be authentic, the method permits data corresponding to the ARINC data to be transmitted to an intended destination.
