Abstract: Methods, systems and devices for an avionics mobile computer device capable of carrying out communications while moving among a plurality of inter-connected networks, and a mobile computer management device for managing moving location information of the mobile computer and transferring packets destined to the avionics mobile computer to a current location of the avionics mobile computer, as well as a mobile computer management method and a communication control method suitable for these devices.

Abstract: Methods, devices, routers and systems for a satellite-ready Satcom Direct router with simultaneous use of Inmarsat, SwiftBroadband, Swift 64, Ku-Band and Ka-Band satellite connections with intelligent traffic control, along with Wi-Fi access and 3G/4G cellular network connectivity. The router is compatible with existing Wi-Fi access points and is backward-compatible with 802.11b/g. Up to four or more simultaneous wireless networks can be supported, allowing multiple systems to operate on aircraft without additional wireless access points and providing 3G/4G network connectivity when the aircraft is on the ground. A downloadable Satcom Direct router mobile App provides on-board cabin services including one or more of moving maps, flight tracker and command and control of satellite links.

Abstract: Method and apparatus are provided for compensation of an RF link between a transmitter and amplifier of a communication system. The apparatus comprises a signal source coupled to the transmitter for providing an RF test signal of a first magnitude to the RF link, a test signal measuring apparatus at the RF input of the amplifier for measuring a second magnitude of the test signal reaching the RF input of the amplifier through the RF link, and an electronically adjustable attenuator serially coupled with the RF link and responsive to differences between the first and second magnitudes so as to provide attenuation in an RF communication signal passing into the amplifier from the RF link such that the sum of RF signal loss in the link and the attenuator has a predetermined value.
