SPbPUT: Radio Communication Network Analyzer for Communication Quality Assessment

2024: Development of a Mobile Quality Assessment System

Scientists at St. Petersburg University of Telecommunications have developed a system for assessing the quality of mobile communications. The university announced this on December 11, 2024. The device helps to quickly and efficiently obtain data on coverage and quality of communication and has already been tested in the Arctic.

The Radio Network Analyzer provides opportunities for monitoring and assessing the quality of cellular networks, which is especially important against the backdrop of the rapid development of fifth and sixth generation networks.

The development consists of two applications: a client Android-applications and a web application for post-analysis. The first application allows you to conduct radio measurements directly on a mobile device and writes data to the logs. files The second application helps to process and analyze the results, creating, for example, thermal maps of network coverage and displaying measurement results at each point of the route.

The analyzer is able to measure signal strength and signal-to-noise ratio, identify serving base stations, assess communication quality in each tested area, can filter data by communication standard, operator and other parameters, which allows operators to more efficiently schedule network operation and find coverage bottlenecks. It supports all basic cellular standards: GSM, UMTS and LTE, and the flexibility of configuration allows you to adapt it to the needs of a particular operator or region.

Key pros of development: the use of standard devices (can work on commercial smartphones, which makes the system affordable and economical, since it does not require the use of special equipment); multilevel data analysis (allows you to both collect communication data and conduct detailed analysis, creating visual reports and coverage maps); support for various network standards (works with basic communication standards and can be refined to support new technologies, including 5G); a wide range of applications (suitable for use at any site where network coverage assessment is required, from urban conditions to remote areas).

The developers of the project are Alexander Prasolov, Andrey Fedorov and Roman Roshchinsky, employees of the Department of Wireless Technologies and Systems of St. Petersburg State Technical University. Their work on the analyzer is aimed at creating an easy-to-use tool for obtaining data on the quality of communication, which can be useful both for large telecom operators and research organizations.

A radio network analyzer is a practical and versatile solution for assessing cellular quality in the field. The system has already proven its effectiveness during testing and is ready for further use in projects to modernize and expand networks, - explained Alexander Prasolov.
