Hughes
Introduces
Multi-Satellite
Gateway
for
HX
System
June
11
Hughes
Network
Systems,
LLC
announced
the
availability
of
its
new
HX
Multi-Satellite
Gateway,
the
latest
enhancement
of
its
advanced
HX
System.
The
new
HX
Gateway
is
pre-wired
for
easy
multi-satellite/multi-transponder
expansion
and
can
be
customized
to
support
additional
satellites
through
the
HX
Expansion
Kit.
As
the
core
element
and
HX
System
master,
the
HX
Gateway
performs
network
management
and
dynamic
bandwidth
assignment
functions.
The
multi-satellite
capability
comes
with
a
new
release
of
system
software
which
also
includes
a
number
of
enhancements
that
benefit
satellite
broadband
operators,
such
as:
- Enhanced TCP/IP acceleration processing, which nearly doubles the throughput capability of HX routers to more than 10Mbps; and
- End-to-end VLAN tagging, which facilitates management of VLAN partitions.
Additionally,
the
HX
Gateway
offers
the
option
to
include
the
high-performance
Configurable
Demodulation
Subsystem
(CDS),
which
supports
10
Msps
of
return
channel
throughput
and
is
configurable
with
up
to 9
separate
TDMA
channels.
The
10
Msps
CDS
also
supports
enhanced
Doppler
correction
and
spreading
inroutes,
which
is
ideal
for
broadband
mobility
applications
on
planes,
trains
and
ships.
"Our
new
HX
Multi-Satellite
Gateway
has
been
designed
to
unlock
the
maximum
value
from
high-quality,
IP
broadband
networking,
including
specialized
applications
such
as
mobility
and
mesh,"
said
David
Jupin,
vice
president,
International
Division,
Hughes.
"It
makes
it
easy
for
operators
to
expand
broadband
services
across
virtually
all
multi-satellite
coverage
situations,
while
maintaining
the
powerful
network
management,
extensive
diagnostics
and
scalability
of
our
proven
HX
System."
Efficiency
and
flexibility
in
utilizing
satellite
bandwidth
is
at
the
core
of
the
HX
System
design.
Based
on
the
industry-leading
Internet
Protocol
over
Satellite
(IPoS)
standard,
endorsed
by
ETSI,
ITU,
and
TIA,
the
HX
System
can
be
readily
configured
to
provide
a
specified
Quality
of
Service
(QoS)
for
each
link
tailored
to a
particular
terminal,
enabling
operators
to
provide
services
tailored
to a
customer's
specific
requirements.
An
optimized
bandwidth
allocation
scheme
is
employed
to
mitigate
cost
of
space
segment,
whereby
idle
terminals
release
their
bandwidth
assignments
to a
shared
pool.
HX
remote
terminals
utilize
FDMA/TDMA
channels
to
communicate
with
the
HX
Gateway
in
star
mode,
or
simultaneously
to
other
terminals
in
mesh
mode,
with
each
channel
supporting
data
rates
up
to
3.2
Mbps.
