Wi-Fi technology is present in homes, universities, restaurants, and pubs worldwide, thus gaining notorious space in communication systems, especially due to smart technologies improvement. However, several devices can interfere with this network, reducing or even causing data loss on transferences. The Electromagnetic Interference (EMI) caused by lighting equipment is a bad-known and little-analyzed phenomenon in Brazil. The massive use of these technologies needs to be evaluated, remarking a critical analysis of its permitted limits. This study aims to verify and evaluate the possible influences that lighting technologies can generate on communication networks (Wi-Fi) through Electromagnetic Interference (EMI). The following article is the result of several tests under the influence of seven different types of lighting sources among thirteen samples to assess the influence of lighting systems on Wi-Fi networks. The tests were made in a shielded environment, on the LabLux -UFF (Laboratório de Luminotécnica da UFF), using the Iperf3 software.

Goal: The objective of this study was to conduct an exploratory literature search capable of identifying the critical success factors for the implementation of sustainable public lighting management in cities. Design / Methodology / Approach: To accomplish this, the chosen method was a systematic literature survey conducted according to the Cochrane protocol, using the Web of Science, Scopus, and Science Direct journal databases. Results: As a result, the study shows that there is a scarcity of scientific literature published in journals regarding the intersection between sustainable management and public lighting. In addition, it became clear that the main practices carried out in this area occur in European cities.  Limitations of the investigation: VOSviewer software was used to build and visualize the bibliometric networks and only two correlated attributes were identified, which shows a lack of similarity between them and demonstrates a limitation of this study. Practical applications: As a practical implication, the present study supports public managers in decision-making regarding sustainable public lighting, demonstrating the need to implement projects in this field. Originality/Value: Although this is an extremely important subject, the search showed few studies published in this field.
