About Data Communication
Available for the FOMA Terminal
Packet communication and
64K data communication
Data communication that can be used between the
FOMA terminal and PCs is classified in 2 categories:
packet communication and 64K data communication.
c
Packet communication
The data is received at the maximum speed of
3.6Mbps and sent at the maximum speed of
384kbps.* Packet communication is charged
according to the amount of data sent and
received, regardless of the time it takes or
the distance. Note that the communication
charge can become expensive when large files
are sent and received. It is also possible to
access a corporate LAN connected to a FOMA
network and exchange data.
a
When you use packet communication with
DoCoMo PDA "sigmarion
Ⅲ
" or "musea", the
communication speed is 384kbps at maximum
for both sending and receiving. It is not
compatible with FOMA HIGH-SPEED Area
communication.
*: The communication speed is 384kbps at maximum for both
sending and receiving outside FOMA HIGH-SPEED area.
c
64K data communication
Data can be sent or received at the stable speed of
64kbps. This type of communication is charged
according to the length of time the line is connected
regardless of the amount of data. Note that the
communication charge can become expensive
when the line is connected for a long time.
■
For packet communication
Packet communication is performed via the
FOMA USB Cable (optional) connected to a PC
or via a dedicated cable connected to a PDA.
Use an access point that supports FOMA packet
communication, such as DoCoMo Internet
connection service "mopera U" or "mopera".
a
DoCoMo Internet service "mopera" is also
available. When you use access points for
"mopera", the communication speed is 384kbps
at maximum for both sending and receiving.
■
For 64K data communication
64K data communication is performed via the
FOMA USB Cable (optional) connected to a PC
or via a dedicated cable connected to a PDA.
Use an access point that supports FOMA
64K data communication, such as DoCoMo
Internet connection service "mopera U".
a
DoCoMo Internet service "mopera" is also
available.
Notice before using
Internet service provider fees
In addition to FOMA service charges, you may
need to pay user fees to an Internet service
provider to use the Internet. These fees must be
paid directly to the Internet service provider in
addition to service fees of FOMA service. Contact
your Internet service provider for details.
DoCoMo Internet connection service "mopera U" or
"mopera" is available. "mopera U" is a pay service
for which you need to apply. "mopera" is a free
service for which you do not need to apply.
Setting an access point (e.g. Internet service provider)
Packet communication and 64K data
communication use different access points. If you
are using packet communication, use an applicable
access point for it; if 64K data communication, use
an access point for FOMA 64K data communication
or ISDN synchronized 64K.
a
You cannot use DoPa access points.
a
You cannot use access points for PHS64K/32K
data communication such as PIAFS.
User authorization when accessing network
Some access points may require your user
authorization (ID and password) when connecting.
Use communication software (Dial-up network) to
enter your ID and password. ID and password will
be provided by your Internet service provider or the
network administrator. Contact the Internet service
provider or network administrator for details.
