[IEEE 2019 IEEE 2nd 5G World Forum (5GWF) - Dresden, Germany (2019.9.30-2019.10.2)] 2019 IEEE 2nd 5G World Forum (5GWF) - The Optical Fiber and mmWave Wireless Convergence for 5G Fronthaul Networks

摘要： In this paper, we have addressed and reported the principal technologies part of the next generation mobile fronthauling networks, namely 5G fronthaul. We also described the main features of these technologies and illustrated their benefit via current and challenging bottleneck network conditions by involving real world scenarios with high demand for innovative solutions. These technologies (such as ribbon optical fibers, RoF, passive WDM, mmWaves) will be most likely implemented in the 5G fronthaul infrastructure. Among these technologies, several technical challenges remain to be addressed such as cost-efficient hardware solutions for RoF transceivers, simple adaptation of RoF techniques over ribbon fibers, optical beamforming in integrated photonics, seamless interfaces between the ribbon fiber media and the radiating elements in the RU sites, and finally remote power distribution to RUs from CO premises.
