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 9.8 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 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 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
