This paper presents an innovative high-bandwidth access network architecture that offers transparent transport services for fixed and mobile applications. Key to this 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(More)
Radio-over-fiber techniques apply to fiber-to-the-home distributions to reach the customer premises with the services to be received with full-standard low-cost equipment. Bi-directional coarse wavelength division multiplexing (CWDM) radio-over-fiber transmission of triple-format full-standard orthogonal frequency-division multiplexing (OFDM) signals in(More)
This paper proposes two fiber-to-the-home bi-directional architectures for triple-play distribution services as being investigated in FIVER project. First, a coarse wavelength division multiplexing (CWDM) architecture is proposed using two wavelengths per user one at 1550 nm and the other at 1300 nm for uplink and downlink information. The second(More)
Wireless and optical integration is pivotal to the exploitation of future access solutions. Optics provides greater bandwidths and long reach while wireless offers easier deployment, mobility and freedom to end users. By combining both, service experience is highly enhanced. Single types of transmission systems indeed have their advantages, but integration(More)
—It is envisaged that end-user access bandwidth requirements will notably increase in the coming years; at the same time, the number of connected mobile devices will also exponentially grow as the fully-digital connected homes (Internet of Things) becomes an everyday reality. This article presents an active remote node (ARN) at an intermediate location(More)

(ICRISAT) is a non-profit, non-political organization that does innovative agricultural research and capacity building for sustainable development with a wide array of partners across the globe. ICRISAT's mission is to help empower 600 million poor people to overcome hunger, poverty and a degraded environment in the dry tropics through better agriculture.(More)
Next-generation 5G converged networks need to support applications requiring ultra-high speed wireless links exceeding 1 Gb/s, e.g. large file transfer and high definition video streaming, e.g. for D2D and D2I communications. Here, we describe wireless networking throughput beyond gigabit rates employing the 24 GHz (unlicensed ISM), and 60 GHz (802.11ad(More)
5G networks aims to tackle the complex demands of emerging business paradigms, such as Smart Cities, eHealth, and Industry 4.0. In this paper, a hierarchical, distributed-intelligence 5G architecture is described, offering low latency, security, and open access as features intrinsic to its design. SDN and NFV principles are employed to create a networking(More)
