AirCard® 595U USB modem - User Guide

Wireless USB modem

Once installed and configured, the AirCard USB modem can connect to the CDMA network automatically. You just insert the AirCard USB modem, allow Watcher to autolaunch and authenticate your account on the network, then launch your Internet browser (which you can also configure in Watcher to launch automatically)—you’re online!

Alternatively, you can make a high‐speed data connection without running Watcher—simply by launching whatever application you want to use (such as your web browser or e‐mail application). Prerequisites: you must have previously selected, in Watcher, “Always-on” for the high‐speed connection and (subject to feature availability) “Enable NIC for data connections”.

The AirCard USB modem also allows you to dial up a modem (such as a corporate server).

CDMA 3G services

The AirCard USB modem 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 Rev. A supports Internet connections with data rates up to 3.1 Mbps (downlink from the network) and

1.8 Mbps (uplink to the network). Average data rates are roughly 600–1300 Kbps (downlink from the network) and 300–400 Kbps (uplink to the network). Actual speed depends on the network conditions.

•1x‐EVDO Rev. 0 supports Internet connections with data rates up to 2.4 Mbps (downlink from the network) and

153 Kbps (uplink to the network). Average data rates are roughly 400‐700 Kbps (downlink from the network) and 40‐80 Kbps (uplink to the network). Actual speed depends on the network conditions.

•1X supports Internet connections with data rates up to 153 Kbps. Actual speed depends on the network condi‐ tions.

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 28.
