No. Wireless network equipment (typically called Access Points) located in the buildings still requires wiring. Only the connection to the device itself (e.g., laptop) is wireless. Generally speaking, wireless networks are not a replacement for wired connections but act to compliment departments and their users. ITS usually recommends the installation of enough wireless infrastructure to allow for "casual" wireless usage. Lobbies, meeting rooms and outdoor patios are just some of the areas that need wiring pulled to allow for access point installation.
