Fiber link design considerations for cloud-Radio Access Networks [PDF]

, 2014
Analog radio over fiber (RoF) links may offer advantages for cloud-Radio Access Networks in terms of component cost, but the behavior of the distortion with large numbers of subcarriers needs to be understood. In this paper, this is presented in terms of

The new flexible mobile fronthaul: Digital or analog, or both? [PDF]

, 2016
It has become apparent that current fronthaul technology cannot be simply extended to meet the projected demands of 5G and beyond mobile systems. This current technology, based on the transport of sampled radio waveforms, has been the preferred option ...

Radio-over-modes for C-RAN architecture with smart optical resources assignment [PDF]

, 2017
In this paper we consider a centralized radio access network (C-RAN) architecture with a fully analog fronthaul link between remote radio heads (RRHs) and baseband units (BBUs) based on the radio over fiber (RoF) paradigm. Mode division multiplexing (MDM)

Analog Radio-Over-Fiber Transceivers Based on III–V-on-Silicon Photonics [PDF]

IEEE Photonics Technology Letters, 2018
Analog radio-over-fiber transceivers allow a substantial reduction in the complexity of the remote radio heads in the wireless network of the future. In this letter, we discuss the building blocks for such a transceiver implemented on a silicon photonics platform, with the heterogeneous integration of III–V devices and the co-integration with ...
