The Design of a High-Performance Network Transceiver for iNET

Abstract

A critical element of the proposed iNET architecture is the development of a telemetry network that provides two-way communication between multiple nodes on both the ground and in the air. Conventional airborne telemetry is based on IRIG-106 Chapter 4 and provides only a serial streaming data path from the aircraft to the ground. The network-centric architecture of iNET requires not only a duplex communication link between the ground and the test article, but also a communication link that provides higher bandwidth performance, higher spectrum efficiency, and a transport environment that is capable of fully packetized Internet Protocol. This paper describes the development path followed by TTC in the implementation of its nXCVR-2000G, an OFDM 802-11a-based iNET-ready IP transceiver.
