Data communication
The data communication modes available from
FOMA terminal and hints on use are explained.
･
FOMA terminal does not support the Remote
Wakeup.
･
FOMA terminal does not support fax communication.
･
When connecting FOMA terminal to DoCoMo’s
PDA “sigmarion Ⅱ ” or “musea” for data
communication, make sure to update “sigmarion
Ⅱ ” or “musea”. For details on update, visit the
DoCoMo website.
Supported communication modes
FOMA terminal supports 3 communication modes:
packet communication, 64K data communication and
data transfer.
These communications become available by
installing the related software on a PC from the
attached CD-ROM, connecting FOMA terminal to a
PC and making required settings.
■ Packet communication
Packet communication charges are based on the
amount of data sent and received, which make it
suitable for high-speed exchange of relatively
small amounts of data such as sending and
receiving mail. No communication charges are
required when no data are exchanged even if you
are connected to the network. Therefore, sending/
receiving data as needed while remaining
connected to the network is possible.
High-speed packet communication provides a
maximum reception speed of 384 kbps and a
maximum transmission speed of 64 kbps by using
access points that support packet communication
on FOMA, such as mopera U / mopera,
DoCoMo’s Internet connection service. These are
offered by Best-effort connection which allows
transmission speed to vary with the environment
and the rate of congestion.
Note that communications of large-size data such
as for viewing and downloading websites
containing images will require high charges.
■ 64K data communication
The 64K data communications allow data transfer/
reception at stabled communication rate of 64
kbps. Communication charges are based on the
duration of the connection to the network
regardless of the volume of data, which make it
suitable for sending and receiving relatively large
amounts of data as in downloading multi-media
contents. Use access points that support FOMA
64K data communication services such as mopera
U / mopera, DoCoMo’s Internet connection service
or ISDN synchronized 64 kbps access points.
■ Data transfer
It is the mode of non-charged communication in
which data are transferred/exchanged via FOMA
USB cable (optional). Various data including the
phonebook, incoming/outgoing mail and
bookmarks are sent/received.
Usage precautions
When using the Internet from PC, usage charge to
your Internet service provider (herein after called as
provider) is generally required. This charge is paid
directly to the provider, and is separate from the
FOMA service charge. For more information on
usage charges, contact your provider.
･
DoCoMo provides 2 Internet connection services:
mopera U and mopera. It requires subscription
and a monthly fee. The mopera U service allows
you to use broadband Internet connection and
international roaming services. There is also a
plan that requires a monthly fee only when you
use the service. The mopera service, however,
allows you to access the Internet without
subscription and monthly fee. You can make a
connection with Internet immediately. For details
such as charges, visit the DoCoMo web site.
Different dialup connections are required for packet
communication and 64K data communication. When
performing packet communication, use the dialup
connection for FOMA packet communication. When
performing 64K data communication, use the dialup
connection for FOMA 64K data communication or
ISDN synchronized 64 kbps data communication.
･
You cannot connect to access points of DoPa.
･
You cannot connect to access points of PHS 64K/
32K data communication such as PIAFS.
Some dialup connections require user authentication
(ID and password) before a connection can be
established. If user authentication is required, you
must use your communication software or dialup
network to enter your ID and password before
connection. Your ID and password will be assigned
by the dialup connection’s provider or network
administrator. For more information, contact your
provider or network administrator.
To authenticate FirstPass (user certificate), you must
install FirstPass PC software from the attached CD-
ROM and configure it. See “FirstPassManual” in CD-
ROM for details.
