Rev 3.3 May.02
The Data tab on the main Watcher window is used to make
data connections for any of these purposes:
• Browsing the Internet
• Sending and receiving e-mail
• Dialing into your corporate network
• Sending and receiving faxes
The AirCard 555 network card offers three types of data
connections:
• Dial-up connection – in this type of connection, the
AirCard 555 functions as a modem. You provide the phone
number and the AirCard dials the number. Using this type
of connection, you can connect to any other modem and
receive faxes. The maximum speed of this type of
connection is 14.4 kbps, or 56 kbps if Venturi compression
software is used to increase the throughput.
• Quick 2 Net connection – in this type of connection, the
AirCard makes a direct Internet connection. The data
transmission speed for this type of Internet connection is
the same as for a dial-up connection but the time required
to initiate the connection is shorter. Quick 2 Net avail-
ability is dependent on your service provider. (This type of
connection is sometimes called Quick Net Connect or
QNC.)
• Express Network connection – in this type of connection,
the AirCard functions as a network card. The AirCard
establishes a high-speed Internet connection to the CDMA
network. (You do not need to provide a phone number and
there is no dialing involved.) The maximum speed of this
connection is 144 kbps but it is only available in areas
where 1xRTT has been implemented.
The Express Network connection provides access to the
Internet. Once the connection is established, you can open
your browser and connect to any web site that is accessible
through the Internet, or access other Internet services (such
as e-mail).
