Fiber-Extended Copper Line Architecture With End-to-End Data Transmission and Link Monitoring Open
We demonstrate a prototype hybrid, full duplex fiber-extended copper line with frequency-reusability and simultaneous fiber and copper line monitoring. The link architecture is composed of three main units: a central office; a remote-node …

Potential for Deep Rural Broadband Coverage With Terrestrial and Non-Terrestrial Radio Networks Open
Since the first generation of cellular networks was rolled out, the priority has been to improve the connectivity and capacity of densely populated areas, such as urban centers, whereas rural areas received less attention. The lower subscr…

Testbed Evaluation of Distributed Radio Timing Alignment Over Ethernet Fronthaul Networks Open
This work investigates a mechanism for alignment of the timing on which spatially distributed and cooperative radio units transmit in radio-frequency (RF) when served over a packet-based fronthaul. It analyzes the problem by considering th…

An LPC-Based Fronthaul Compression Scheme Open
<p>Several new architectures are under investigation for cloud radio access networks, assuming distinct splits of functionality among the network elements. Consequently, the research on radio data compression for the f…
