Hybrid FSO–THz Technologies for 6G Access Networks: A Cost-Availability Trade-off Analysis
Paper i proceeding, 2025
Free space optics (FSO) and terahertz (THz) communication are emerging as promising wireless technologies to meet the high data rate and low-latency requirements of 6G access networks. However, assessing their techno-economic feasibility is essential before widespread deployment. This paper
analyzes the cost and availability trade-offs of hybrid FSO–THz deployments in mobile access networks, considering multiple topologies and geographic scenarios. It also evaluates their use as protection mechanisms under network failure conditions. The findings provide practical guidance on target cost and performance thresholds, helping equipment vendors and operators design resilient and cost-effective 6G access solutions.
