5G Maritime Ultra-long Range Coverage Technology Research and Practice
This paper mainly studies the key technologies required for 5G networks in ultra-long coverage scenarios in maritime areas. It analyzes the main challenges of ultra-long coverage in sea areas,including the propagation differences of 5G frequency bands and the influence of site height on coverage distance. In-depth research is conducted on the key technical points of adjusting the TDD time slot structure,expanding coverage capability through T+F time-frequency aggregation to improve uplink robustness,and coverage simulations were carried out based on the Longley-Rice model for 2.1 GHz and 3.5 GHz. Finally,the effectiveness of the solution was verified through engineering practice,providing experience and reference for the coverage scenarios in marine areas.
