Fundamental investigation of extending 4G-LTE signal over MMF/SMF-FSO under controlled turbulence conditions

In this paper, we propose a hybrid radio over multi-mode/single-mode fibre and free space optics (RoMMF/SMF-FSO) system to enhance the 4th generation-long term evolution (4G-LTE) signal performance when used in local area access networks. A single mode fibre pigtailed gradient index lens is used to minimise the modal effect of the optical link at different… CONTINUE READING
