Abstract [sv]

I takt med att efterfrågan på trådlös kommunikation med hög hastighet ökar och det ökande antalet enheter som är trådlöst anslutna har forskare börjat utforska kompletterande teknologier. Hybridnätverk bestående av LiFi och WiFi är en kombination av Light-Fidelity och Wireless-Fidelity som kombinerar dataöverföring över både radiovågor och ljus. Hybridnätverk med LiFioch WiFi är ett lovande system där hastigheter över 10 Gbps är möjliga och teknikerna inte kan störa ut varandra. Den systematiska litteraturstudie som genomförts syftade till att kartlägga fördelar, nackdelar och utmaningar vid implementationen av dessa hybridnätverk. Sökningar efter litteratur för studien gjordes i fem olika databaser med hjälp av en specifik sökterm, vilket resulterade i 43 accepterade artiklar. En kvalitativ metod, tematisk kodning, användes för att hitta svaren, vilket resulterade i att 20 subteman identifierades spridda över de tre olika huvudteman. Analysen visade att den mest frekvent rapporterade fördelen var prestanda, den vanligaste nackdelen var handover och den mest framträdande utmaningen var load balancing. 

Abstract [en]

With the increasing demand for high-speed wireless communication and the growing numberof devices connected wirelessly, researchers have started exploring complementary technologies. Hybrid LiFi and WiFi networks are a combination of Light-Fidelity and Wireless-Fidelity, which combine data transmission over Radio Frequency and light. Hybrid LiFi and WiFi networks are a promising system that offers speeds above 10 Gbps without interference from one another. The conducted systematic literature review aimed to discover the advantages, disadvantages, and challenges of implementing a hybrid LiFi and WiFi network. The search for literature was conducted in five different databases using one search term, resulting in 43 accepted articles. A qualitative approach using thematic coding was conducted to find the answers, resulting in 20 sub-themes divided over the three main themes. The analysis showed that the most frequently reported advantage was performance, the most common disadvantage was handover, and the most appearing challenge was load balancing.
