From the Manufacturer
The freedom of wireless can now be upgraded to extreme speed with the new Macsense AeroCard Extreme (WPE-800). AeroCard Extreme is a plug-and-play 802.11g wireless card that fits into any Cardbus slot and adds wireless capability to PowerBooks and laptop PCs.
AeroCard Extreme can send and receive data up to speed of 54Mbps, which is 5 times faster than the existing 802.11b standard. Using the same Apple AirPort driver for Mac OS X, it is fully compatible with Apple AirPort and AirPort Extreme base stations, as well as other IEEE 802.11b and 802.11g-compliant access points.
With your laptop and the AeroCard, you are free to work where you want to work. Surf the Net from the comfort of your couch during the big Sunday game. Or review your stock portfolio in bed. Answer your email at the kitchen table with a cup of coffee. The convenience of where and when you want to connect to your network, or the Internet, is now yours. And with AeroCard Extreme, you can now enjoy all that in extreme speed.
Compatible with Mac OS X (10.2 and above) and Windows 98-XP, AeroCard Extreme offers the unique cross-platform compatibility.
