Introduction to the PinPoint X
Rev 4.0 Oct.09

If
you
need
to
contact
your
PinPoint
X,
a
device
connected
to
the
PinPoint
X,
or
a
host
system
using
the
PinPoint
X
from
the
Internet,
you
need
to
have
a
known
IP
(such
as
one
which
is
static)
or
domain
name
(an
IP
address
which
is
converted
by
a
DNS
server
into
a
word
based
name).
If
you
have
a
dynamic
IP
address
for
your
modem,
you
can
use
a
Dynamic
DNS
service
(such
as
IP
Manager)
to
translate
your
IP
address
into
to
a
domain
name.
Caution:
If you want to connect remotely to your PinPoint X using
TCP/IP, the IP address given to your modem by your cellular provider
cannot be a private or internal IP address (such as a special private
network) unless you are on the same network or inside that network’s
firewall (such as with frame relay).
Communication HSUPA
Many
of
the
GSM
Networks
have
been
expanded
to
HSUPA.
HSUPA
HSUPA
(High
‐
Speed
Uplink
Packet
Access)
is
a
cellular
technology
which
most
closely
resembles
a
broadband
synchronous
connection.
The
upload
and
download
speeds
are
maximized
to
provide
a
faster
throughput,
reaching
speeds
up
to
2.0
Mbit/s
for
the
uplink
and
7.2
Mbit/s
for
the
downlink.
Please
check
with
your
network
provider
on
the
availability
of
HSUPA.
HSDPA
HSDPA
(High
‐
Speed
Downlink
Packet
Access)
is
a
cellular
technology
allowing
for
higher
data
transfer
speeds.
In
HSDPA
mode
of
operation,
max
speeds
are
up
to
7.2
Mbit/s
in
the
downlink
and
384
kbit/s
in
the
uplink.
HSDPA
uses
Adaptive
Modulation
and
Coding
(AMC),
fast
packet
sched
‐
uling
at
the
Node
B
(Base
Station)
and
fast
retransmissions
from
Node
B
(known
as
HARQ
‐
Hybrid
Automatic
Repeat
Request)
to
deliver
the
improved
downlink
performance
vs.
UMTS
and
EDGE.
HSPDA
(and
HSUPA)
falls
back
to
UMTS,
EDGE
or
GPRS
(in
order
of
precedence).
This
feature
allows
you
to
have
seamless
connectivity
no
matter
where
your
PinPoint
X
is.
