Unbundling in Current Broadband and Next-Generation Ultra-Broadband Access Networks

Photonic devices for next-generation broadband fiber access networks

Next-generation Broadband Wireless System

INTRODUCTION AS optical fiber networks have become available to end users, the type of content being accessed on the Internet is changing away from text and imageoriented information towards high-volume data such as sound and video. At the same time, there is a growing trend towards the combined use of personal computers and mobile terminals (e.g. mobile phones) because using a mobile terminal ...

Special Section on Next Generation Broadband Access Technologies

Existing broadband access systems include ADSL over metallic wires, optical media converters, B-PON, GE-PON, and G-PON systems. Recent innovations such as the higher speed systems of 10G-PON, 10GEPON, and WDM-PON are receiving a lot of attention, and low cost and mass production technologies for high speed wide bandwidth systems should be developed. New optical access network architecture also ...

Long-term drivers of broadband traffic in next-generation networks

This paper is concerned with long-term (20+years) forecasting of broadband traffic in next-generation networks. Such long-term approach requires going beyond extrapolations of past traffic data while facing high uncertainty in predicting the future developments and facing the fact that, in 20 years, the current network technologies and architectures will be obsolete. Thus, “order of magnitude” ...

Optimal Relay Station Placement in Next-Generation Relay-based Broadband Wireless Access Networks

To satisfy the stringent requirement of capacity enhancement in wireless networks, cooperative relaying is envisioned as one of the most effective solutions. In this paper, we study the capacity enhancement problem by way of Relay Stations (RSs) placemen to achieve an efficient and scalable design in nextgeneration relay-based broadband wireless access networks. To fully exploiting the performa...
