Abstract

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.
