Today's era of digital times is based on robust mobile network coverage for proper communication, data sharing, and internet connectivity. However, rural, as well as urban, areas are mostly subjected to interruptions in the strength of the signal as well as network quality because of infrastructural shortages and geographical limitations. To bridge such flaws, this project introduces a light-weighted, cost-effective, and portable 5G Network Tester. The product operates on an ESP32 microcontroller and a SIM card module A7600 which is 5G-capable and able to read and output real-time RSSI signal strength, recognize active operator, and determine current network type (from 2G to 5G. There is also instant feedback output given in the form of dBm on an OLED display screen for users to view in network performance in the field. Power and connectivity with the SIM module is through AT commands in serial communication and a solar-powered power bank, making it energy-friendly and portable. This single device, designed for any environment, performs network field testing in any condition and provides telecom professionals, planners, and researchers with a convenient solution. Keeping real network information on the road, the 5G Network Tester facilitates more efficient connectivity testing, supports planning infrastructure, and helps build better communication networks in rural areas. testers, telecom providers, emergency responders, and general users who need to analyze and optimize 5G connectivity in different locations.
