Analog radio-over-fiber solutions in support of 5G

摘要

We introduce Centralized (C-RAN) architectures combined with analog optical transport schemes to realize high-speed lanes between BBU pool and RRHs. The DSP-enabled architecture relies on the use of a powerful digital engine supporting data plane functions for both fiber-wireless parts. The presented concept is also supported through preliminary experiments demonstrating the proof-of-concept operation of a Fiber-Wireless link. IFoF/mmWave transmission of single-band radio signals at 60-GHz is demonstrated for Downlink directions using QAM-modulated signals at 1 Gbaud.
