Fully compliant with the industry-leading IPoS standard, the HN9400 is a powerful satellite router featuring high performance on both the DVB-S2/ACM forward channel, as well as the adaptive LDPC coding return channel. An advanced, Hughes-developed LDPC coding scheme on the return channel provides significant error coding improvement over turbo code resulting in minimum use of satellite bandwidth. The adaptive coding on the return channel enables the unit to dynamically change FEC rates, burst-to-burst, based on link conditions, to achieve the highest throughput while maintaining high link availability. Through the combination of adaptive LDPC coding and a powerful processor, the HN9400 supports upstream burst rates of 3.6 Mbps, making the HN9400 an ideal platform for next-generation, high-throughput satellite systems.

To enable superior end-user performance, the HN9400 includes a full set of integrated Wide Area Network (WAN) optimization features. Accelerated TCP and HTTP performance features, including HTTP pre-fetch (objects are locally cached on the HN9400) along with DNS caching, enable fast Web browsing. Integrated header and packet payload compression both conserves bandwidth and contributes to high performance.
A full-featured IP router, the HN9400 supports a switching capacity up to 5,000 packets per second eliminating the need for an external router. IP routing and addressing features implemented in the HN9400 include the RIPV2 and BGP routing protocols, virtual router redundancy protocol (VRRP) with policy-based routing, DHCP server or relay, as well as network address translation (NAT) and port address translation (PAT). The HN9400 also handles end-to-end VLAN tags complying with the 802.1P and Q standards and each VLAN may be configured with its own quality of service (QOS). Government and enterprise users can be confident of the security of information running over the HN9400, as it uses a hardware-based conditional access system and optionally AES 256 encryption for user traffic.
Network operations are easy to perform as the HN9400 features an integrated Web server supporting a Web browser interface for commissioning and troubleshooting. Full-featured, built-in diagnostics provide historical information about network performance or error conditions. An integrated LAN sniffer eliminates the need for onsite presence during trouble-shooting. The HN9400 is centrally managed for software configurations and downloads.

The HN9400 incorporates an innovative adaptive LDPC coding scheme, developed by Hughes, on the return, enabling superior modem performance. The adaptive LDPC’s ability to run with minimal link margin results in maximum bandwidth efficiency. Additionally, the HN9400’s use of variable burst LDPC code block lengths sized to the amount of IP data to be transmitted further increases the return channel efficiency. Overall, the adaptive LDPC coding on the return channel yields more than 20 percent bandwidth efficiency improvement over competing systems.
Technology Marketing Corp. (TMC) recently honored Hughes with its 2010 Satellite Spotlight Product of the Year Award for the company’s innovative, dual Ka/Ku-band HN9400 satellite router. The newest member of its market-leading family of broadband satellite routers and modems, the HN9400 boasts several technology firsts and is spearheading the industry’s move to highthroughput Ka-band satellites from prior generation Ku-band systems.
Fully compliant with the IPoS/DVB-S2/ACM industry standard, the HN9400 supports up to 60 Mbps of throughput on the forward channel, and is the first to incorporate advanced adaptive LDPC coding on the return channel. This results in up to 20 percent improvement in link performance, thereby enabling very efficient use of satellite capacity. Capable of operating in Ka- or Ku-bands and with upstream rates of up to 3 Mbps, the HN9400 is an ideal platform to deliver even the most bandwidth-demanding services on today’s satellites, while being future-proof for next-generation, high-throughput systems. Continuing the Hughes tradition of innovation, this award-winning router is helping to unlock the many benefits of broadband connectivity for enterprise and government customers globally.
DVB-S2 Spectral Efficiency
The DVB-S2 Satellite system
The most recent enhancement to the DVB series of standards is DVB-S2, which introduces several important features that together provide signifi cant spectral effi ciencies when compared with DVB-S and proprietary (non-DVB) channel formats. DVB-S2 provides for both 8 PSK as well as QPSK modulation and uses a powerful FEC system based on concatenation of BCH with LDPC (Low Density Parity Checking) inner coding.
The LDPC technology was developed by Hughes and adopted by the DVB standards committee as the basis for the new DVB-S2 standard. The result of the BCH/LDPC coding is only 0.7 db from the Shannon limit. This is signifi cantly better performance then any proprietary turbocode—the best of these appear to operate about 2 dB from the Shannon limit. Figure 2 shows the performance of DVB-S2 against DVB-S, as well as a typical proprietary turbocode signal.
The bottom line for operators is that the DVB-S2 standard can provide 2.25 bits per Hz or more, an increase of 30- 40% over conventional DVB-S carriers, resulting in better bandwidth economics.
