Abstract
An access scheme for a wireless LAN station to connect an access point on the network. This scheme allows a wireless station to finish all the processes from search to registration with an AP at a very high speed. Firstly, the time interval of beacon transmission is shortened when a wireless station is powered on. Secondly, the authentication phase in traditional registration with an AP is eliminated. Instead, a period of time on each channel is reserved. Accordingly, the wireless LAN station can use this period to exchange control frames with the AP without competing with other stations to access wireless medium. This results in quick access to the network.
