Network demonstration techniques are disclosed which allow a fully- operational, secure wireless network (100) to be implemented at a customer location. Using only a portable authentication server (110), a laptop comput er (105), and at least two access points (115, 120), a wireless network can be set up at the customer location within a matter of minutes, so that a user o f a portable computing device (125) having an appropriate network interface ca rd (127) is able to roam throughout the customer location with the benefit of a wireless connection to one of the access points. The laptop computer (105) contains software integrating the functionality of a security server (135), a user authentication database (130), and other components (140, 145) necessar y to implement the wireless network. The user may also be able to communicate with the laptop computer (105) and authentication server (110) from location s external to the customer location, perhaps using a wireless wide area networ k or secondary wireless local area network. Using the network demonstration an d related information about the customer, accurate cost estimates for installi ng a company-wide wireless network can be generated.
