Análisis de la coexistencia de redes WI-FI y sistemas de posicionamiento en tiempo real para el tráfico de datos y el posicionamiento de objetos.

Abstract

Since the increase of connected devices, technology development such as wearables, smart cities among others, Wi-Fi (Wireless Fidelity) nets get saturated up to 2.4 HGz so the speed worsens and the market changes constantly up to 5 GHz. This research work is focused on describing and implementing a real time location system at IEEE (lnstitute of Electrical and Electronics Engineers) 802.15.4-2011 in order to determine the coexistence between Wi-Fi nets which works in 5GHz and real time location systems. An experimental study in closed and opened environments has been developed, using ubikiti Loco M5 antennas. The location system has been implemented by using the transceiver DW 1000 with UWB (Ultra Wide Band) antenna. Some important data about traffic, speed and Cartesian coordinates was collected in different scenarios. Traffic and speed data were gathered through software packs Wireshark and Colasoft Capsa, the Cartesian coordinates were collected through Matlab and the remaining information in SPSS. Since the objective was to analyze the coexistence between Wi-Fi and location systems, there has been an affectation in the data dispersion of the real time location systems. The obtained results will be quite useful when planning electronic systems that use all these mentioned technologies. As suggestion, it is also vital to analyze the transmission systems attempting to keep them with safe bands and improve the algorithms to manage the data in the location systems.
