Abstract

En stasjonsstyreenhet (SME) styrer en retningsantenne for en stasjon for å kommunisere med et aksesspunkt (AP) i et 802.11 protokollsystem. SME-en kan styre antennen før eller etter at en 801.1 I er autentisert og innmeldt aksesspunktet. I løpet av en passiv skannesyklus beveger styreprosessen antenneposisjonene gjennom de tilgjengelige antenneposisjonene og monitorer en signalmåleverdi assosiert med et AP beacon-signal, eller et annet forutbestemt signal, for å finne en beste pekeretning basert på, for eksempel, en mottatt-signalstyrke-indikasjon (RSSI). I løpet av en aktiv skannesyklus, der aksessprobing benyttes, går prosessen gjennom antenneposisjonene og monitorerer en prøvesignalrespons for å finne den beste antenneposisjonen. Tilleggsskann kan gjennomføres basert på en beslutning om at det mottatte signalnivået til den for tiden valgte antenneposisjonen har falt under en på forhånd bestemt terskel.
