A novel approach to achieve wavelength controlled optical beam steering using a 45° tilted fiber grating (TFG) for full-duplex indoor optical wireless transmission is proposed and experimentally demonstrated for the first time. The 45° TFG functions as an in-fiber passive diffraction device for wavelength steered light emission and reception, which enables full-duplex optical wireless transmission...
Coverage at millimeter-wave (mmW) frequencies is a constraining bottleneck. Spatial diversity and spatial multiplexing multiple-input multiple-output (MIMO) improve performance over a spread of user locations and these can benefit from wider antenna spacing. Radio-over-Fiber (RoF) transport provides flexibility in deploying a number of widely-spaced Remote Antenna Units (RAUs) connected to the same...
The performance of Time Division-Long Term Evolution (TD-LTE) Radio-over-Fiber (RoF) networks is investigated in this paper, in terms of downlink Physical Data Rate (PDR). It is shown that the accommodation of the extra propagation delay induced by the optical fiber links increases the protocol overheads and reduces the protocol's efficiency.
The growing importance of wireless communications has been driving the research and development of advanced network architectures to enable the cost-effective support of large numbers of users at very high data rates. In this context, the FUTON project aims to fulfil the objectives of the so-called 4th Generation (4G) wireless communications through an innovative Distributed Antenna System (DAS) with...
