Mobile fronthaul is an important network segment that bridges wireless baseband units and remote radio units to support cloud radio access network. We review recent progresses on the use of frequency-division multiplexing to achieve highly bandwidth-efficient mobile fronthaul with low latency. We present digital signal processing (DSP) techniques for channel aggregation and deaggregation, frequency-domain...
We propose a novel mobile fronthaul transmission scheme to achieve bandwidth-efficient transmission of both the I/Q waveforms of wireless signals and the control words (CWs) between baseband units (BBUs) and remote radio units (RRUs). Unlike the common public radio interface (CPRI) where the I/Q waveforms and the control words are transmitted as a binary sequence in the time domain, the proposed transmission...
This paper presents a techno-economic comparison between classical passive optical networking (PON) and innovative convergent radio and fibre architectures, based on intermediate aggregation at the remote base station (RBS) of both, fixed and mobile subscribers. By aggregating users at an active remote node (ARN) co-located at the RBS, which offers high-speed switching and statistical-multiplexing...
This paper presents an innovative high-bandwidth access network architecture that offers transparent transport services for fixed (≥ 1 Gbps) and mobile applications (LTE and beyond). The main novelty is the development of a high-functionality, low-energy active remote node (ARN) offering high-speed switching and statistical-multiplexing features for maximal exploitation of available network resources,...
The optical and wireless communication systems convergence will activate the potential capacity of photonic technology for providing the expected growth in interactive video, voice communication and data traffic services that are cost effective and a green communication service. The last decade growth of the broadband internet projects the number of active users will grow to over 2 billion globally...
Numerous aspects of home networks, from physical layer and architectures to applications and economics, are described in this paper. Trends and requirements for fiber-in-the-home (FITH) are highlighted.
Todaypsilas access network is migrating towards broadband IP, fixed/mobile convergence and service convergence. Thus, the next generation access network (NGAN) requires a converged optical/wireless access network infrastructure, other than the existing architecture that connect to the cellular, broadband wireless, and optical access networks separately, which complicate the network and increase the...
