The HN System is the carrier-grade system from Hughes, optimized to support medium- to large-scale satellite broadband networks and the ideal solution for service providers and large enterprises that demand the highest performance and quality for their customers. 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.

The HN System is the most advanced and widely deployed satellite broadband infrastructure worldwide from the leader in broadband satellite networks and services. Compliant with the IP over Satellite (IPoS) global standard, the world’s first to be approved by TIA, ETSI, and ITU, the HN System is the ideal choice to deliver high-speed IP services over satellite, supporting an expanding range of multi- media, video, data, and voice applications.

HN System Architecture

The HN System 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 System can be readily expanded to accommodate multiple 121 Mbps forward channels and over 70 Mbps of return channel traffic, all in a single rack.

Efficiency and flexibility in utilizing satellite bandwidth are at the core of its design. For example, one or more terminals can be selected for guaranteed inroute bandwidth, while the remaining terminals share fair access via a truly dynamic bandwidth assignment algorithm. Inactive remote terminals are released from all network resources thereby optimizing the use of network resources for active terminals.

The HN System’s unmatched flexibility, efficiency, and high quality of service have earned it the reputation as the most advanced and cost-effective technology available in the marketplace.

The IPoS Advantage

The Hughes family of satellite terminals and routers is compliant with the global IPoS standard, the only standard approved by the TIA, ETSI, and ITU standards organizations. IPoS enables Hughes broadband routers/terminals to provide superior performance and efficiency by providing a clearly defined interface conforming to the ETSI SI-SAP standard. IPoS provides truly dynamic bandwidth assignment—remote sites requiring no traffic capacity are assigned no resources. Finer granularity allows a lower average burst overhead, thereby increasing efficiency.
