HX System The HX system was officially released in June 2006 as a platform designed specifically for smaller networks with a high quality of service requirement. Hughes took the basic structure of the larger HN system – including the DVB-S2 ACM outbound, inbound access schemes and the management system – as the core of the HX. For this reason, observers can be forgiven for initially thinking the HX is little more than a cost reduced version of its larger brother, but this is not the case. Quality of Service: The ability to delivery high levels of guaranteed service in a much more granular way that large scale enterprise systems need, or can even cope with, is one key feature and this was possibly the largest task that Hughes set out to deliver in its HX system. As a consequence, despite the fact that the company had a great deal of technology which could simply be lifted out of the HN system, most if not all of the QoS software systems, including the algorithms, needed to be completely re-designed. The company also wanted to raise the maximum transmit rate of the remote terminal and to design an architecture that was both low cost and yet scaleable. Traditionally, Hughes has been highly focused on maintaining backwards compatibility in its systems, but as the HX system was targeted at new markets it was released from this constraint and had a clean slate on which to start. Low Cost with High Functionality: As a consequence, the HX offers an almost unique combination made up from the advantages of highly scaleable, efficient, low cost technology taken from a proven and successful product coupled with a hub systems and IP architecture designed from the ground up. Hughes has long term plans for the system, but in the present version there are several major differences between the HX and the HN: ?? Quality of Service capabilities are significantly expanded with the ability to set service guarantees by individual remote terminal and specific application. These include: ?? Constant bit rate providing a uniform transmission rate to avoid jitter in applications such as voice and video. ?? Minimum committed information rate (CIR), guaranteeing the throughput of a connection, with fixed steps to a maximum limited rate. ?? Minimum CIR with best effort to a maximum limited rate ?? Best efforts services - weighted fair queuing ?? Class-based weighted prioritisation QoS is also tied to an operator-defined priority queue which sets four levels of IP traffic and allows the system to prioritise and rate limit the least critical traffic in an ordered fashion. ?? Inbound transmission speeds have been raised from the maximum of 1.6 Mbps on the HN7000S terminals to 3.2 Mbps on the HX terminals. ?? Optional 128 bit AES encryption.

Service for Demanding Customers: Hughes is targeting the HX system at operators focused in highly defined market segments such as the booming maritime stabilised business, oil & gas, embassy network and multi-national corporate segments. It has also firmly targeted the demand for high speed satellite backhaul circuits from the GSM operators and the highly military’s need for highly customised mobile terminals capable of supporting multi-megabit mission critical applications. The combination of a low entry point and a DVB-S2 ACM outbound channel, especially in a market struggling with rising prices across the world and a real lack of satellite capacity in some regions, has proven to be an attractive one. Additionally, the system offers many of the advantages of the HN in that the HX50 terminal is priced similarly to the HN7700 due to the fact that it comes from a heritage of huge manufacturing scale. The HN system is also very efficient in its use of compression, Hughes’ performance enhancing proxy (PEP) and adaptive inbound selection (AIS) as well as its ability to reduce a non-active remote terminal’s bandwidth requirement to zero.

Provision of Greater Flexibility: In the longer term, the HX will become much more distinguishable from the HN. Whilst both systems will see increases to the inbound transmission rates, new FEC rates and more efficiency driven out of improved acceleration and compression technologies, the HX be upgraded to be able to support mesh connectivity. Mesh is a generic term which can imply many things, but specifically we expect to see full terminal-to-terminal connectivity on demand and a multi-gateway capability. This is likely to allow an operator to terminate traffic from an HX VSAT at different gateway locations depending on the performance and cost available at that site. So, for example, an operator in West Africa could (satellite coverage permitting) operate a local gateway n Africa supporting corporate intranet traffic, a gateway at the AIX for internet and a gateway in New York for voice termination.
Operators who have bought the system, several as a replacement or service platform upgrade to competing products Hughes has targeted, tell us the HX’s capabilities are impressive and it delivers exactly the kind of service that it was designed for. What is more, many operators are looking for some kind of technical differentiation and as a new product with a strong heritage, the HX offers this as well as the security of stability. Hughes is a bankable name in this business and its engineering capabilities are well known and respected, giving the customers we have interviewed a sense of assurance with respect to the future of the platform and the support from its manufacturer.

HX VSAT Hub
The HX Satellite system
In June 2007 Hughes Network have signed an agreement to deploy an advanced HughesNet™ HX broadband VSAT satellite hub for the provision of Internet data services out of the Turin, Italy, Eutelsat Skylogic teleport. The system is being run and managed by Hughesand Skylogic. It utilizes the latest technology in broadband satellite Internet not yet seen in Europe and the Middle East.
It is one of the first HX hub with advanced features including high speed return links, extensive QoS support, plus DVB-S2 with adaptive coding and modulation, which significantly improves space segment efficiency.
In November, 2007 Hughes Network announced the successful conclusion of extensive integration testing of the Hughes broadband satellite platforms in providing cellular backhaul links for Telma Madagascar. The Hughes HN and HX platforms were integrated with several manufacturers' GSM and CDMA equipment and Telma has now placed these links into active service. After a competitive evaluation, Telma had earlier purchased both Hughes HN and HX series network operating centers (NOCs) and 300 broadband satellite terminals, which are used to deliver rural telephony, corporate telephony, Internet access, intranet, and wireless backhaul services. The CDMA links support residential and payphone services, while the GSM links support mobile services. The Hughes broadband satellite systems have been tested extensively and the results are fully compliant with a full carrier-class backhauling service. “We are very pleased to be using equipment from Hughes, the proven leader in broadband satellite.” Demand for cellular service continues to grow worldwide, and HughesNet HN and HX satellite solutions are a cost-effective and rapid answer to reaching customers in more remote or difficult coverage areas. Telma has selected HX satellite internet platform to help expand their cellular footprint throughout Madagascar .”
