Abstract
A wireless station is connected to a wireless network through an access point and can establish a direct client-to-client connection to a second wireless station. The wireless station can communicate directly with the second wireless station without involving the access point. The wireless station communicates with the wired network and with other wireless stations through the access point. The second wireless station may have an infrastructure connection to the access point or may be independent.
