A Cross-Sectional, Year-Long Study of 5G Uplink Performance," Proceedings of IFIP Networking Conference (Networking 2024), Thessaloníki, Greece, June 2024.


After a rapid deployment worldwide over the past few years, 5G is expected to have reached a mature deployment stage to provide measurable improvement of network performance and user experience over its predecessors. In this study, we aim to assess 5G deployment maturity via three metrics: (1) Does 5G performance remain stable over a long time span? (2) Does 5G provide better performance than its predecessor LTE? (3) Does the technology offer similar performance across diverse geographic areas and cellular operators? We answer this important question by conducting a cross-sectional, year-long measurement study of 5G uplink performance. Leveraging a custom Android App, we collected 5G uplink performance measurements (of critical importance to latency-critical apps) spanning 8 major cities in 7 countries and two different continents. Our measurements show that 5G deployment in major cities appears to have matured, with no major performance improvements observed over a one-year period, but 5G does not provide consistent, superior measurable performance over LTE, especially in terms of latency, and further there exist clear uneven 5G performance across the 8 cities. Our study suggests while 5G deployment appears to have stagnated, it is short of delivering its promised performance and user experience gain over its predecessor.
