The purpose of this paper is to evaluate WiFi performance of the ESP32 module in outdoor scenarios. This was done by measuring the received signal strength indicator (RSSI) at different point of a relatively open area, prone to possible sources of interference, in order to simulate a real-life usage situation. The results show that it is possible to use this device at distances up to 300m from the wireless access point. Based on the acquired RSSI values, the achievable data rate was also estimated for each point.
This manuscript shows the development of an open infrastructure that aims to be free and available for anyone interested in developing IoT applications. The idea is that users can use the infrastructure without concerning about the details of the IoT network. This manuscript shows some details of the infrastructure implementation and the provided documentation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
