3.4 Usage Model
l Ad-hoc Networking
Ad-hoc network also is called Peer-to-Peer network. Without Access Point, notebook
users with each 11Mbps Wireless High Rate PC card can build a Ad-hoc Peer-to-Peer
wireless networks to share files with each other, share a public office printer and other
peripheral resources, and even access the Internet via a modem.
l Infrastructure Networking
802.11b-compatible Access Point is a bridge or router for connect to the wired
Ethernet network and wireless network. Through the deployment of Access Point,
wireless LAN can be extended to the reach of a wired network. Therefore, A notebook

user with 11Mbps Wireless High Rate PC Card can access to fixed local network
resources.
2. Installation for Windows 95 and 98
2.1 Software Installation
l Windows find a new hardware described as INTERSIL-HFA384x/IEEE and then
show a dialog to ask for the driver of this new hardware.
l Please insert the CD-ROM labeled 11Mbps Wireless High Rate PC Card.
l If your CD-ROM Drive is located in the D drive. Please execute the setup program on
CD-ROM. For examples,
D:\Setup <Enter>
