High-Performance IP Routing

Built on a solid foundation of IP features and functionality, the HN/HX systems are the solutions for satellite routing where full IP functionality is required together with performance.

Designed and optimized for carrier-grade IP broadband networking and specialized applications such as mobility and mesh networking, Hughes brings to the market the HX System—a broadband satellite system with an economical gateway earth station and high performance remote terminals.

The core component of the HX System is the HX Gateway, which acts as the system master and includes the network management and dynamic bandwidth assignment manager. The HX Gateway uses a DVB-S2 carrier with Adaptive Coding and Modulation (ACM) for the outbound channel received by all HX System remote terminals. HX remote terminals utilize FDMA/TDMA channels to communicate back to the HX Gateway (star mode) or to each other (mesh mode). The FDMA/TDMA channels of the HX System are highly efficient and are based on the industry-leading standard, Internet Protocol over Satellite (IPoS), which has been endorsed by ETSI, ITU, and TIA. The HX System FDMA/TDMA channels of the HX System support data rates up to 3.2 Mbps.

Efficiency and flexibility in utilizing satellite bandwidth are core to the design of the HX System. Each link, in star or mesh mode, can be configured to provide a QoS tailored for an individual remote terminal. And each remote link can be independently configured with unique Commited Information Rates (CIRs), thereby allowing a service provider to develop a service tailored to their customers’ specific requirements. In addition, the HX System bandwidth allocation scheme is designed so that idle terminals can be configured to release all bandwidth assignments thus ensuring optimal bandwidth utilization.

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 FDMA/TDMA performance and efficiency.

Clearly defined interface conforming to the ETSI SI-SAP standard enables back-end systems to work easily with the Hughes infrastructure
Truly dynamic bandwidth assignment; remote sites with no traffic are assigned no resources
Finer granularity allows a lower average burst overhead, thereby increasing efficiency
