HN Systems

Carrier-Grade Satellite Broadband System

The Hughes HN and HX systems are one of the most advanced and widely deployed satellite systems around the world.

Owned and operated by Hughes to provide Hughes broadband services in North America, Europe, India, and Brazil the same HN and HX systems are also available to operators, enterprises, and governments who wish to operate their own satellite broadband services. Utilizing geostationary satellite coverage available from a choice of operators worldwide, the comprehensive family of Hughes broadband solutions provides the capability to deliver broadband IP services virtually anywhere.

Optimized for broadband IP services, Hughes systems support a wide variety of applications, from high-speed Internet/intranet access, to video conferencing, to voice (VoIP), and adhere to industry standards for voice, video, and serial data protocols.

Hughes broadband satellite systems are compliant with IPoS, including DVB-S2 with Adaptive Coding Modulation (ACM), the world’s most successful satellite industry standard, approved by TIA in North America, ETSI and ITU in Europe, and together with Hughes-patented technology advantages provide unsurpassed capabilities for broadband applications and services.

Hughes systems enable operators and enterprises to deliver a comprehensive range of services including:

  • Broadband Internet access
  • Cellular backhaul
  • Communications on the move
  • VoIP telephony
  • Private IP for corporate intranet
  • Multicast data delivery


  • IPoS Compliant, including high-speed DVB-S2 with ACM outroute
  • Adaptive Inroute Selection (AIS) for maximum bandwidth efficiency
  • Extensive suite of services
  • Field proven, cost-effective and scalable from a few to 100,000’s of terminals
  • Integrated and robust network security with integrated outbound encryption and conditional access
  • Full set of integrated applications including TCP acceleration, IP routing, and optional “pre-fetching” of HTTP content for even faster web throughput
  • Service level control providing the ability to have multi-level QoS offerings
  • Complete range of remote broadband terminals
  • Flexible configurations with multiple networking topologies: star, mesh, and multi-mesh

Carrier-Grade Satellite Broadband System

The HN System is a carrier-grade hub system from Hughes, optimized to support medium- to large-scale satellite broadband networks and the ideal solution for enterprise, government, and consumer/small business markets. The HN System family consists of the HN NOC (Network Operations Center or Hub) and HN terminals (routers, modems, and appliances), which operate over C-, Ku-, or Ka-Band satellites.

HN System's Applications

Broadband Internet access

Cellular Backhaul

Private IP network for corporate intranets including:

  • Banking and Financial
  • Retail
  • Oil and Gas
  • Travel

Public services including:

  • Telephony Internet Kiosk
  • Education
  • Government
  • High availability networking
  • Multicast data delivery
  • Multimedia applications including MPEG4 video

Broadband Hub

The core of the HN System is the HN hub, which manages high-speed IP traffic flow among terminals over the satellite. Compliant with IPoS/DVB-S2 with ACM (Adaptive Coding and Modulation), the world’s most successful satellite industry standard, the HN System hub consists of baseband processing equipment, IF subsystem, control subsystem, and network management system (NMS).

The HN hub is designed as a compact and efficient single-rack package that is highly modular and scalable, enabling rapid provisioning of any mix of satellite broadband services from a single, comprehensive platform. The base configuration of the HN hub can be readily expanded to accommodate multiple 121 Mbps forward channels and over 70 Mbps of return channel traffic, all in a single rack.

Unsurpassed in flexibility and scalability, the HN System is designed with a highly efficient architecture incorporating numerous advanced features, including guaranteed quality of service (QoS) levels for bandwidth management and industry-leading advanced acceleration and compression technologies.

Broadband Satellite Modems, Routers, and Appliances

The System supports a full range of remote equipment supporting a variety of user applications. The remote equipment in the HN System comprises satellite modems, satellite routers and optional appliances, such as voice appliances and serial appliances. Every Hughes terminal and appliance is fully compatible with virtually any IP enabled device.
