Abstract
En fremgangsmåte for å operere et aksesspunkt i et trådløst lokalt nettverk (WLAN) er gitt. Aksesspunktet inkluderer en retningsantenne for kommunikasjon med et flertall av fjerne stasjoner, og retningsantennen inkluderer et flertall av antennemønstre. Fremgangsmåten inkluderer å opprette en antennedatabase ved å assosiere aksesspunktet og hver fjerne stasjon med en respektivt målt signalkvalitet samsvarende med flertallet av antennemønstre. De respektive målte signalkvalitetene blir bestemt av aksesspunktet basert på kommunikasjoner med hver fjerne stasjon. Fremgangsmåten inkluderer videre å bestemme for hver fjerne stasjon et foretrukket antennemønster basert på antennedatabasen, og å velge en fjern stasjon og tilsvarende foretrukket antennemønster for å kommunisere med dette. Det er også bestemt basert på antennedatabasen og tidligere kommunikasjon med den valgte fjerne stasjonen, dersom noen ikke-valgte fjerne stasjoner har potensial for ikke å være klar over når slike kommunikasjoner faktisk finner sted.
