    Connectivity Evaluation of ESP32 in Outdoor Scenarios

    Data de publicação: 03/05/2023

    The purpose of this paper is to evaluate WiFi (IEEE 802.11 b/g/n)
    performance of ESP32 modules in outdoor scenarios using an offthe-
    shelf access point (AP). This was done by measuring its received
    signal strength indicator (RSSI) and application data transfer rates
    at different locations of a relatively open area, prone to possible
    sources of interference, in order to simulate a real-life usage situation.
    The results show that this setup is suitable for medium data
    rate applications at distances up to 300m from the wireless access
    point. Based on the acquired RSSI values, the achievable data rate
    on the PHY layer was also estimated for each point based on the
    hardware documentation. Throughout the text, challenges faced
    during the implementation of the system are shared, as well as
    the solutions found, which will be useful for those who wish to
    replicate the experiment.
