Kontron has partnered with Thales to design and manufacture the Enhanced Terminal Wireless LAN Unit (eTWLU) for the Thale’s GateSync system, a high-performance wireless ground connectivity solution for airports and airlines. The eTWLU, a critical element of the system's onboard networking, is a small sealed ARINC-763-compliant wireless transceiver that supports multiple high-speed wireless protocols, allowing the GateSync system to be deployed at airports throughout the world. The system enables airlines to wirelessly load and offload content and data while an aircraft is on the ground.
The Kontron eTWLU features the high performance PowerPC processor architecture. In order to ensure maximum connectivity throughput and reliability to off-aircraft networks, the Kontron eTWLU is integrated with multiple radios: two 802.16-2006 WiMAX radios supporting 10MHz channels operating from 5.725 – 5.875 GHz, a single 802.11a/g Wi-Fi radio, and a GPRS/EDGE/HSPA-capable GSM radio. The multi-radio approach maximizes the aircraft’s ability to communicate with ground networks. Also, an internal GPS receiver reports equipment locations to the GateSync network operations center (NOC) and software management system.
Kontron designed the eTWLU for maximum aircraft flexibility and network compatibility. When deployed as a stand-alone device, it delivers connectivity for interactive command and control and file transfer for system data exchange. When used in conjunction with the Thales TopSeries IFEC system, the eTWLU supports a broadband connection to enable the delivery or updates of IFE multimedia content. Critical to the deployment, the integration was designed with COTS products in a flight-ready chassis that fits within the footprint specified by ARINC-763.
GateSync has been field tested at major airports and verified by major equipment manufacturers and several airlines, and will soon be deployed.
