Windows Vista helps you with the wireless network experience for home, mobile, and business PCs in a number of ways. The Network Awareness feature keeps your programs optimized for the network's changing capabilities. Windows Vista offers support for wireless security protocols, including WPA2. Windows Vista helps you avoid connecting to fraudulent wireless networks that seem like legitimate hotspots but, in fact, are not. You can also easily create ad-hoc (PC-to-PC) wireless networks for use with peer-to-peer activities such as file sharing.
