Abstract:
The burgeoning marine economy necessitates robust 5G communication capabilities. However, offshore 5G coverage is inherently constrained by the limited reach of terrestrial base stations, and systematic empirical data on its performance in such environments remains scarce. To bridge this knowledge gap, this study conducted comprehensive empirical measurements of 5G network performance from April 29-30, 2025, utilizing the "Zhe Yu Ke 2" as a mobile testbed in an offshore region extending up to 69 km from the coast. Systematic measurements were conducted on critical performance metrics, including end-to-end latency, uplink/downlink transmission rates, Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), and Signal-to-Interference-plus-Noise Ratio (SINR), across the 700/850/1800/2100 MHz frequency bands. The empirical results indicate that while 5G can provide fundamental communication services within 69 kilometers offshore, its performance significantly degrades with increasing distance. Notably, the 700 MHz band demonstrated superior capabilities for extended coverage and maintaining more consistent data rates. This study provides crucial empirical evidence for the strategic planning and optimized deployment of marine 5G networks, facilitating critical applications,such as offshore wind power monitoring and smart shipping.
