[Satellite TODAY 04-19-12] Hughes Network Systems has completed a series of technology trials on its HX System for the Australian Defense Force (ADF), which analyzed the effects of transitioning from legacy Frequency Division Multiple Access (FDMA) systems to an IP-based Time Division Multiple Access (TDMA) architecture, Hughes announced April 18.

      The trials were conducted across ADF satellite payloads in X- and Ku-band utilizing an HX System comprised of fixed and transportable gateways, the HX280 satellite broadband router and advanced network management system.

      “We are proud to have supported the ADF through these important, discrete technology trials and are extremely pleased with the results,” Hughes Defense and Intelligence Systems Division Vice President and General Manager Rick Lober said in a statement. “Utilizing our HX System allowed us to integrate Force elements with a single satcom technology — providing a true joint operational capability — and demonstrated the increased communication capabilities and bandwidth efficiencies possible by employing an advanced TDMA waveform.”
