Installation and Use

on Notebook PCs

5: Data Connections

• Dial-Up Connections

• Quick 2 Net

Connections

• Express Network

Connections

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:

Note: You cannot have a data

and a voice connection at the

same time. If you have a data

connection when an incoming

call occurs, your caller will get a

busy signal or be put through to

your voice mail box.

• 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.)

Note: Depending on your billing

plan, there may be a surcharge

for 1xRTT calls.

• 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).
