Introducing the AirCard® 555 Wireless Network Card

Rev 3.5  Feb.05

Every 

 network operates on one of three radio 

frequency bands. As a dual-band product, the AirCard 
operates on two of these bands (see 

), providing a wide 

coverage area.

The AirCard provides all the advantages of 

 where it is 

available while allowing you to use the older CDMA 

 

standard where 1X has not yet been implemented. The benefits 
to you are that you can use the AirCard in any area that has 
coverage (assuming there are no account restrictions) and you 
will be able to take advantage of the fastest possible data trans-
mission speed.

Required to control, monitor, and manage your wireless 
connections, this includes the Sierra Wireless Watcher™ appli-
cation, and on notebook computers, the Network Adapter 
Manager for selecting your network connection card. The 
device drivers are the software that enables the AirCard to 
work with your computer’s operating system.

The AirCard comes with a CD containing this software:

Watcher application that you use to manage the AirCard 
and monitor your connections. Use the application’s 

 for step-by-step instructions to access features of 

Watcher.

Network Adapter Manager application (for notebook PCs 
only) that allows you to switch between the AirCard and 
other network cards. This application also handles the 
autolaunch of Watcher when you insert the AirCard.

The device driver software that provides the interface 
between the AirCard and your Windows

®

 operating 

system.

The driver and application software must be installed before 
you insert the AirCard for the first time. Detailed instructions 
are provided in the following chapters.

Companies that operate 

 networks and provide access 

to these networks are called service providers. You must have an 
account with a CDMA service provider to use the AirCard.
