Installation Guide

Network card

On notebook PCs, during high-speed packet connections, the AirCard is a true network card, functioning just like the network cards familiar to most corporate computer users. Once installed and configured, the AirCard can connect to the CDMA network automatically. You just insert the AirCard, allow Watcher to autolaunch1 and authenticate your account on the network, then launch your Internet browser—you’re online!

Modem

As a modem, the AirCard allows you to dial up any other modem (such as a corporate server), or send and receive faxes.

Phone

You can connect a headset (sold separately) to the AirCard and use it as a phone. Make and receive calls using digital voice quality, and have the security of emergency 911 access.

Short Messaging Service (SMS) is also available to exchange brief text messages with other CDMA subscribers.

CDMA 1X services

The AirCard operates over a type of wireless network called

CDMA (Code Division Multiple Access).

CDMA 1X technology provides a variety of connectivity features, depending on your service provider and account:

•High-speedpacket data, sometimes known as 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. With this type of connection, the AirCard functions as a network card.

Once the connection is established, you can open your browser and connect to any web site that is accessible

1.Autolaunch is supported on notebook PCs only.

Running Watcher is optional—a high-speed connection is initi- ated upon insertion of the AirCard, provided:

a)you have enabled, in Watcher, “Always-on” for the high- speed connection, and

b)WiFi coverage is either not available, or is available but no WiFi profiles have been set to autoconnect.

However, to make use of other features of the AirCard, you must run Watcher.
