A Network Card, a Modem, and a Phone
On notebook PCs, during 1xRTT connections, the AirCard 555
is a true network card, functioning just like the network cards
familiar to most corporate computer users. Once installed and
configured, the AirCard connects instantly to the CDMA
network with a few mouse clicks. You can just insert the
AirCard 555, click a few buttons, launch your Internet
browser, and you’re ready to web surf.
As a modem, the AirCard 555 allows you to dial up any other
modem, or send and receive faxes. You can also connect a
headset to the AirCard 555 and use it as a phone.
