HX90 High-throughput router for Ku- and Ka-band

The HX90 is a high-throughput capable and highly scalable satellite router that enables operators to provide cost-effective satellite broadband services over Ku- and Ka-band networks. Supporting up to 60 Mbps of multicast traffic throughput, 45 Mbps of UDP throughput or 15 Mbps of TCP throughput, the HX90 delivers exceptional performance. The HX90 includes the full suite of HX System Quality of Service (QoS) features which enable operators to tailor service plans to meet the needs of the most rigorous end users. High-throughput satellite operators can use the HX90 to deliver enterprise and carrier-grade services to users in a cost-effective manner.

HX System Architecture

The HX System provides true IP broadband connectivity via satellite. The HX System is based on a “star” network topology where the outbound channel is DVB-S2 with Adaptive Coding and Modulation (ACM). The return channel of the HX System is multi- frequency FDMA/TDMA using the IPoS standard for broadband over satellite. With a DVB-S/DVB-S2 outbound carrier and transmit rates up to 3.6 Mbps, the HX90 provides a cost-effective and highly scaleable solution for satellite broadband networks.

Efficiency and flexibility in utilizing satellite bandwidth are at the core of the HX90 design. Each link can be configured to provide a QoS tailored to the requirements of the remote site. This includes adaptive Committed Information Rate (CIR) and Constant Bit Rate (CBR) services that provide guaranteed bandwidth through optimising use of the bandwidth during periods of idle or light traffic. Remote sites with less stringent bandwidth requirements or service level agreements can be configured for best-effort service, thereby allowing service providers to develop a service tailored to their customers’ specific requirements. In addition, the HX System bandwidth allocation scheme uses Aloha channels for initial bandwidth assignment which results in very efficient use of space segment. This frees up unused bandwidth and allows an operator to make more efficient use of space segment resources.
