Hughes Announces Next Generation Broadband Satellite Platform Supporting DVB-S2 Standard

Hughes First in Industry to Implement Adaptive Coding and Modulation Feature

    GERMANTOWN, Md., May 9 /Xinhua-PRNewswire/ -- Hughes
Network Systems, LLC (HUGHES), the world's leading provider
of broadband satellite network solutions and services, today
announced the introduction of its next-generation platform,
the HN System, which will support the most efficient
implementation of the DVB-S2 industry standard with ACM
(Adaptive Coding and Modulation).  The HN system is also
compliant with IPoS (IP over Satellite, the first global
satellite industry standard approved by TIA in North
America, and ETSI and ITU in Europe.

    Hughes' implementation of DVB-S2 with the ACM feature,
as defined in the standard, gives Hughes customers higher
system availability and greater throughput for a given
antenna size.  The HN system optimizes link performance,
even in networks with geographically diverse locations and
in high rain areas, by adjusting error-correcting codes and
modulation dynamically based on signal quality feedback from
HN remote terminals.  The greatly improved Low Density
Parity Check (LDPC) error correcting codes, combined with
the adaptability features, make the Hughes solution the
most efficient DVB-S2 platform on the market today. 

    "The HN System with DVB-S2 will take satellite
broadband performance to the next level," said Pradman
Kaul, Hughes Chairman and CEO.  "Along with higher
speeds and improved bandwidth, our newest system solution
will also provide significantly improved operational
efficiency.  This truly will unlock the full power of
DVB-S2 for system operators and for their customers."

    The new HN7000S remote platform consists of the HN7700S
for high-end enterprise and government applications, the
HN7000S for less demanding business requirements, and the
HN7740S for integrated VoIP and broadband services.  These
remote terminals will support both DVB-S and DVB-S2
standards, providing operators an easy transition to
DVB-S2.  The DVB-S2 NOC (Network Operations Center)
configurations include the HN NOC(LX), a full-size NOC, and
the cost-effective and scalable HN NOC(CX) for small initial
network requirements.  The NOCs support both DVB-S2 and
DVB-S remote terminals. 

    The HN platform can be easily configured to support a
wide range of data rates, giving international service
providers a great deal of flexibility in designing their
service plans.  Key features of the Hughes DVB-S2 standard
implementation include QPSK and 8PSK modulations for higher
throughputs; efficient LDPC coding; and ACM for improved
availability and power conservation. 

    Shipment of the DVB-S2 compliant product line to
international service providers will begin by late Q2 2006.


    HughesNet(TM) solutions and services based on DVB-S2
will be announced as they are rolled out at Hughes-owned
and operated facilities in the US, Europe, Brazil, and
India.
