Abstract

Bežične lokalne mreže (WLAN) omogućuju bežični prijenos podataka u određenim geografskim područjima.Ovaj završni rad bavi se izradom WLAN čvora pomoću Raspberry PI uređaja, s mogućnostima konfiguracije kao pristupne točke ili klijenta. Ovaj čvor, osim što služi za komunikaciju, koristi se i kao instrument za mjerenje kvalitete usluge WLAN mreže, s fokusom na pokazatelje poput brzine prijenosa i razine signala. U različitim konfiguracijama Wi-Fi istražen je utjecaj interferencije između pristupnih točaka na brzinu prijenosa i jačinu signala. Rezultati su pokazali da je optimalno postavljanje pristupnih točaka na kanale koji se ne preklapaju, ili na one kanale koji se preklapaju minimalno, ukoliko preklapanje nije izbježivo.

Abstract (english)

Wireless Local Area Networks (WLAN) enable wireless data transmission within certain geographic areas. This thesis involves the creation of a WLAN node using a Raspberry PI device, with capabilities of configuration as an access point or client. Besides serving for communication, this node is used as an instrument for measuring the quality of service of the WLAN network, focusing on indicators like data transfer speed and signal strength. The impact of interference between access points on data transfer speed and signal strength in different Wi-Fi channel configurations was also explored. The results showed that optimal placement of access points is on non-overlapping channels, or on those channels with minimal overlap, if overlap is unavoidable.
