This master thesis explores the technological fundamentals of lighting networks, represented by wired and wireless communication principles. Amongst the first considerations, linked to lighting control systems is the question of why to have it, therefore the first chapter focuses on the numerous advantages and possibilities which are provided by the use of smart lighting. Presence detection, brightness control loops or colour temperature adjustments are only some of the helpful enrichments users and facility managers benefit from. To determine the further benefits of smart lighting systems, and far more important, to enable troubleshooting, a certain amount of background knowledge regarding signal transmission and wired networks is required. The past five years have shown a significantly increasing demand for wireless lighting systems. As a result, a huge number of proprietarily as well as standardized technologies have entered the market leading to an uncontrolled growth. This thesis enlightens a selection of promising wireless technologies and the main leading wired lighting control protocol for professional lighting: DMX. The high frequency field bus DMX is an area, which has frequently caused communication issues. The relatively high sensitivity for disturbances increases the probability for issues on commissioning due to constantly changing environmental influences. The aim of this thesis is to elaborate the impact of certain influences on the network, such as electromagnetic interferences or suboptimal electrical installation. A compact catalogue of executed tests and a summary of recommendations regarding installation, commissioning and the entire electrical surrounding of lighting networks is an appreciated outcome.
