With the increasing demand of wireless spectrum, the offloading of data onto an Optical Wireless Channel (OWC) is emerging as viable means to overcome the crowded radio spectrum for highly-localized communication systems. However, these systems introduce new challenges due to the directionality of light, especially under mobility scenarios. We present Opt-LTE, a Light Fidelity (LiFi) system based on 3GPP LTE in Frequency Division Duplex (FDD) mode, realized with the software suite srsRAN and Software Defined Radios (SDRs). Opt-LTE was implemented as a prototype and evaluated in a small testbed. We analyzed the feasibility of a point-to- point communication and also of a mobility scenario with a S1 handover between two eNodeB (eNB). Experimental results reveal that our approach offers excellent point-to-point performance for most use cases. Moreover, the system guarantees seamless mobility with only little handover latency. Opt-LTE demonstrates that LTE is a feasible option for LiFi systems, utilizing an existing solution for seamless mobility.
