ENGLISH ABSTRACT: Wi-Fi Direct is a recent expansion to the very successful 802.11 Wi-Fi technology. According to Wi-Fi Alliance, Wi-Fi Direct is being broadly adopted, among others by Google’s Android (since version 4.0 Ice Cream Sandwich). However, to the authors’ knowledge no formal testing of Wi-Fi Direct throughput, latency, packet loss and energy use on smartphones has been performed. This thesis presents practical measurements of Wi-Fi Direct capabilities on Android smartphones in practical use-case driven applications. It was found that Wi-Fi Direct would be well suited to content sharing applications and possibly also gaming applications. Furthermore, tests showed that Wi-Fi Direct is more sensitive to communication range and uses more energy compared to standard Wi-Fi. However, with some improvements to this technology, also discussed in this thesis, and on-going development in Android, Wi-Fi Direct could become a reliable and ubiquitous device-to-device communication medium.

AFRIKAANSE OPSOMMING: Wi-Fi Direct is ‘n nuwe uitbreiding tot die 802.11 Wi-Fi tegnologie. Volgens Wi-Fi Alliance, word Wi-Fi Direct al hoe meer ingesluit in elektroniese toestelle, veral in nuwer Android selfone. Android word ontwikkel deur Google, ensluit Wi-Fi Direct funksionaliteit in vanaf weergawe 4.0 Ice Cream Sandwich. Egter, Android se Wi-Fi Direct datatempo, pakkie vertraging, pakkie verlies en energie verbruik is nog nie in ‘n formele akademiese werk gemeet nie. In hierdie tesis word die vermoeëns van Wi-Fi Direct getoets in praktiese Android toepassings. Die toetse het getoon dat Wi-Fi Direct gepas is vir foto- en videoverspreiding toepassings. Speletjie toepassings kan moontlik ook ondersteun word deur Wi-Fi Direct. Daar is gevind dat Wi-Fi Direct meer sensitief is vir kommunikasie afstand en meer energie intensief is as standaard Wi-Fi. Egter, met sekere verbeteringe (ook bespreek in hierdie tesis) en voordurende ontwikkeling deur Android, kan Wi-Fi Direct as ‘n betroubare en alomteenwoordige ewe-knie kommunikasie medium uitblink.
