“…However, the improvement in spectral efficiency offered by A-RoF, compared to current D-RoF technology is enormous, particularly considering future network scaling. For example, currently deployed Common Public Iadio Interface (CPRI) bit rate option 3 requires 2.457 Gb/s fronthaul transmission, while the user throughput is only 150 Mb/s [33]. With the inevitable scaling of this data rate, and the number of connected users, the required CPRI fronthaul transmission rates have the potential to reach to 100's Gb/s per cell, which is clearly unsustainable.…”

“…A big issue with moving to mmWave frequencies is the higher path loss therefore multiple distributed antenna units are needed to provide coverage to an area and it is preferable to consolidate baseband units (BBU) and share capacity across remote radio heads (RRH) [6], [7]. Typically, digital optical fiber links carrying common public radio interface (CPRI) data have been used to connect BBUs to RRHs as shown in Fig.…”

An analog radio-over-fiber photoreceiver based on a resonant narrowband transimpedance low noise amplifier (TILNA) is proposed and demonstrated for use in low-cost and low-power remote radio heads for distributed antenna systems in the unlicensed 60 GHz band. The amplifier is designed to present a conjugate matched impedance to a wirebonded photodiode where the input impedance has a real part of 10Ω while the output impedance is matched towards 50Ω. Fabricated in a 55nm SiGe BiCMOS technology, the TILNA features a three stage common emitter low noise amplifier with 17 dB of gain, a 3.4 dB noise figure, an output 1-dB compression point of 8 dBm and low power consumption of 33.6 mW while occupying only 0.25 mm 2 of chip space including pads. The photoreceiver, formed by the TILNA and a wirebonded InP UTC photodiode, offers 29 dB higher gain than a 50Ω terminated reference photodiode where 11 dB improvement is provided by resonant matching. Experimental results show that the proposed photoreceiver has achieved up to 20 Gbps C-band transmission of complex modulated waveforms over 5 km of standard single-mode fiber using 4 Gbaud QAM32 with an RMS EVM of 11.5%.

“…To that end, Analog-Radio-over-Fiber (A-RoF) technology has received increased attention from the research community mainly by virtue of its capability to meet both the centralization and high fronthaul capacity needs [5][6][7][8]. This is achieved by placing all main hardware, i.e., sampling and digital-to-analog conversion components, within the BBU, hence significantly simplifying the RRHs compared to Digital-Radio-over-Fiber (D-RoF) technology [9].…”

A. Mesodiakaki 1[0000−0001−9309−0524] , P. Maniotis 1 , G.Abstract. Next generation, i.e., fifth generation (5G), networks will leverage both fiber and wireless (FiWi) technology to meet the challenging 5G traffic demands. Moreover, a Cloud-Radio Access Network (C-RAN) architecture will be mainly adopted, which places the BaseBand Units (BBUs) at centralized locations, thus offering cost-efficient energy supply and climate control. To this end, efficient Medium Transparent-Medium Access Control (MT-MAC) protocols are needed to ensure the optimal exploitation of both media. In this paper, we propose a gated service MT-MAC protocol (gMT-MAC) for Millimeter Wave (mmWave) Analog Radio-over-Fiber (A-RoF) C-RANs. GMT-MAC grants a transmission window to each user equal to the time needed for its requested traffic to be successfully sent. A mean packet delay model is also proposed and verified by means of simulation. The performance of gMT-MAC is evaluated for different network load conditions, number of Remote Radio Heads (RRHs) and optical availability values. The provided results prove the suitability of gMT-MAC to meet the sub-ms delay requirements of latency-critical 5G services.Keywords: Fifth Generation (5G) networks · mean packet delay model · fiber-wireless (FiWi) · millimeter wave (mmWave) · cloud-radio access networks (C-RANs) · analog radio-over-fiber (A-RoF) · medium transparent-MAC (MT-MAC).
