Key performance metrics such as Total Radiated Power (TRP) and Total Isotropic Sensitivity (TIS) were used to scale and assess connectivity between the LTE module antennas and base station. A root-cause analysis identified factors causing poor antenna performance and theoretical data supported solutions to streamline testing processes. The results offer a framework to enhance connectivity ensuring remote control of AC EV chargers as mandated by the Open Charge Point Protocol (OCPP). © 2025 Elsevier B.V.
