Abstract We propose and experimentally demonstrate a 2.333-Tbit/s bi-directional optical mobile network using optical wireless communication (OWC). The proposed network architecture is divided into: fronthaul network connecting between the distributed-unit (DU) and the remote-radio-unit (RRU); and midhaul network connecting between the central unit (CU) and the DU. At the midhaul, an aggregated 2.333-Tbit/s transmission is achieved using wavelength division multiplexed (WDM) infrared (IR) based invisible light communication (IVLC). For the link between the RRU and user-equipment (UE), 2.7 Gbit/s white-light visible-light-communication (VLC) transmission is achieved for indoor 1.5 m transmission. It can provide communication and lighting simultaneously. A gateway (GW) is also proposed acting as the interface between the IVLC and VLC transmissions. In the proposed architecture, about 400 VLC end-users can be supported.

使用光无线通信 (OWC) 的 2.333-Tbit/s 双向光移动网络

摘要 我们提出并实验证明了使用光无线通信 (OWC) 的 2.333-Tbit/s 双向光移动网络。建议的网络架构分为：连接分布式单元（DU）和远程无线电单元（RRU）的前传网络；以及连接中央单元 (CU) 和 DU 之间的中程网络。在中程，使用基于波分复用 (WDM) 红外 (IR) 的不可见光通信 (IVLC) 实现聚合 2.333 Tbit/s 传输。对于RRU和用户设备（UE）之间的链路，室内1.5 m传输实现了2.7 Gbit/s白光可见光通信（VLC）传输。它可以同时提供通信和照明。还建议使用网关 (GW) 作为 IVLC 和 VLC 传输之间的接口。
