MMW Fronthaul and Backhaul System
摘要
Millimeter-wave transmission systems based on radio over fiber techniques are discussed for application to fronthaul and backhaul links in advanced radio access networks. The seamless convergence between millimeter-wave and optical signals is realized by analog radio over fiber techniques in both optical-to-electrical and electrical-to-optical signal conversions. The configuration of radio over fiber transceivers is introduced along with their advantages for the realization of millimeter-wave signals, followed by a discussion of example systems for millimeter-wave wireless fronthaul and backhaul connections.
