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) com-
munication 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 perfor-
mance thresholds, helping equipment vendors and operators
design resilient and cost-effective 6G access solutions.
