Imagine being able to conduct all your Internet business without having to plug in to a cable port or telephone jack.
All you need is to make sure your laptop or PC has the ability to plug in such a card and that the place where you're working offers wireless access.
The cards are lightweight and small -- about the size of a thick credit card.
Joyce Vonada, vice president of information technology services for AutoNation Inc., says being able to connect to the Internet "anytime, anywhere
can be a lifesaver."
While Vonada did not specify a particular card, Drouin of TRW is a fan of the Sierra Wireless AirCard 580.
He says: "Finally, a broadband wireless card that delivers on its performance promises. I can work almost as efficiently as being in my office, even when stuck for hours on the tarmac."
