AirCard® 580 Wireless WAN Modem - Installation Guide
8
Wireless WAN modem
Once installed and configured, the AirCard can connect to the
CDMA network automatically. You just insert the AirCard,
allow Watcher to autolaunch and authenticate your account on
the network, then launch your Internet browser—you're
online!
As a modem, the AirCard also allows you to dial up any other
modem (such as a corporate server).
CDMA 3G services
The AirCard operates over a type of wireless network called
CDMA
(Code Division Multiple Access).
CDMA 3G technology provides a variety of connectivity
features, depending on your service provider and account:
•
1x‐EVDO supports Internet connections with data rates up
to 2.4 Mbps (downlink from the network) and 153.6 kbps
(uplink to the network). Average data rates are roughly
700 kbps (downlink from the network) and 153.6 kbps
(uplink to the network). Actual speed depends on the
network conditions.
•
1X supports Internet connections with data rates up to
153.6 kbps (downlink from the network) and 76.8 kbps
(uplink to the network). Actual speed depends on the
network conditions.
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).
The connection is "active" when data transmission is
occurring. If data transmission stops for a period of time
(determined by the network), the connection becomes
"dormant"; see page
29.
•
Circuit switched (dial‐up) data, using the earlier CDMA
IS‐95 specification, supports data connections to any dial‐
in service at rates up to 14.4 kbps.
•
QNC (Quick Net Connect), provides a simplified way to
dial into an Internet connection (using circuit switched
data) where 3G (1xEV‐DO or 1X) high‐speed packet
service is not available.
•
SMS
(Short Message Service), allows you to send and
receive short text messages using the AirCard.
