Enhancing Wireless Backhaul Networks With Parallel FSO-mmWave Systems: Experimental Analysis and Availability Assessment

IEEE Open Journal of the Communications Society
In this work, we report the deployment and experimental analysis of a hybrid free-space optical (FSO) and millimeter-wave (mmWave) backhaul system over a 1.2 km link to connect an under-served area.

High-Capacity Coherent FSO

A paradigm-changing revolution on the area of high-speed wireless communication systems is currently being forced by the unstoppable increase on bandwidth demand. Due to spectrum exhaustion, traditional radio frequency (RF) communications can hardly cope with the foreseen requirements for next-generation cellular and satellite communications.
