Software and Compatibility Issues
A WLAN is inherently more complex than a wired network. In the latter case, all
you have to worry about is the proper connections at each termination point, the
proper components, and the proper installation techniques. However, a WLAN
actually takes you beyond the physical connection into the network hardware and
driver software.
For example, to install a WLAN, you must install the W-NIC into the work-
station and install the driver software, either from disk or from CD. To install the
AP, you must install conventional LAN wiring to a workstation outlet near the
server, securely mount the server and antenna, and connect the network and power
connections.
