The growth in demand for LTE network services has outpaced current technical requirements, making it necessary to conduct analyses and field studies to determine the use and performance of the radio spectrum. Measuring and detecting spectrum usage in LTE is fundamental for mobile operators seeking to optimize coverage and service. This paper presents a compact, modular LTE measurement platform integrating GPS-based geolocation for real-time acquisition and monitoring of key performance indicators (KPIs). The hardware architecture centers on an ESP32 microcontroller coupled with a SIM7600G-H LTE communication module, enabling the simultaneous capture of geographic coordinates, cell identifiers, and physical-layer power metrics. The portability of the measuring instrument, thanks to its battery power, facilitates data acquisition, providing autonomy for spectrum measurement activities. This offers a dynamic, efficient and low-cost solution for network fault diagnosis and mobile network planning. Using the experimental field methodology, it can be inferred that the SIM7600G-H module operates in a range between -32dBm and -59dBm with a good signal, and the mobile phone between -72dBm and -88dBm with a marginal signal with a tendency to disconnect at the edge of the cell. Finally, the advantages and uses of portable devices and their potential application in resizing mobile networks as a spectrum measuring tool are observed.
