Hughes Enhances Efficiency and Performance of the JUPITER VSAT System

Hughes Network Systems, LLC (HUGHES), the global leader in broadband satellite networks and services, has released a new set of features for its Very Small Aperture Terminal (VSAT) platform for broadband satellite services. The JUPITER System is already one of the most widely used VSAT systems in the world. It is the system of choice for network operators, governments, mobile networks, and aeronautical and maritime service providers. Packaged into the new Release 7.4 are the company's latest improvements in return channel performance and efficiency as well as new functionality supporting Layer 2 network implementations.

Some of the Enhancements Available in JUPITER System Release 7.4 Include:

  • Adaptive Coding and Modulation (ACM) on Time Division Multiple Access (TDMA) Return Channels: For many years, satellite operators have enjoyed significant efficiencies through the implementation of ACM on the DVB-S2X forward channel. Now, with ACM on the TDMA return channel, operators can realize similar efficiencies – up to 30% bandwidth savings, in some cases.
  • Dynamic Return Channel Switching: Another new feature is the ability to switch return channels automatically, based on traffic characteristics, processing MF-TDMA (with ACM) and DVB-S2X transmissions.
  • New Functionality for Layer 2 Transport Support: These advances enable higher efficiency through extended implementation of acceleration of higher level protocols within the Layer 2 transport scheme.

Creating one of the largest Layer 2 satellite backhaul networks in the world, JUPITER System technology has been installed at more than 1,500 cellular base stations providing universal services to citizens throughout Indonesia. The project, which was announced last year, involves multiple service providers, including Pasifik Satelit Nusantara (PSN), deploying cellular backhaul and Internet access sites throughout the country.
