Electromagnetic spectrum monitoring of LTE channels based on SDR portable sensor: preliminary analysis

Year: 2022

Type: conference-paper

Abstract: This paper presents preliminary research for the implementation and testing of a Software Defined Radio (SDR) sensor with electromagnetic spectrum monitoring capabilities for measuring signals specific to the Long-TermEvolution (LTE) mobile communications standard. The proposed sensor is developed on the ADALM Pluto SDR platform - and is designed to acquire a bandwidth of at least 20MHz. To determine the spatial extent of the measurements, the sensor also includes a GPS (Global Positioning System) module. The hardware control of the sensor is performed both in stationary variant using a laptop and in mobile mode using a low-cost module - Raspberry Pi. Present findings suggest that the designed SDR solution represents a reliable and low-cost alternative for real-time spectrum monitoring of wideband signals like the case of 4G-specific signals. The cost of the whole implemented monitoring system is about EUR 330.
