Looking for new DNA: The world around IMT-advanced

Technology, such as IMT-2000 and IMT-A, plays an important role in our society. A number of prominent authors and thinkers have judged the impact of technology as being increasingly radical. This paper connects different visions on technology, thereby bringing different perspectives on innovation into line. An important motivation for this paper...

Layer 2 and 3 contention resolution and radio-over-fiber in OCDMA PON for transparent optical access in personal networks

In this paper, we analyze, for the first time, the eminent role of optical transparent networking in personal networks. We show how an optical access network mitigates many issues with respect to connectivity and mobility management. A concrete personal network user-scenario deduces requirements for such an architecture. A combination of passive...

First experiences with Personal Networks as an enabling platform for service providers

By developing demonstrators and performing small-scale user trials, we found various opportunities and pitfalls for deploying Personal Networks (PNs) on a commercial basis. The demonstrators were created using as many as possible legacy devices and proven technologies. They deal with applications in the health sector, home services, tourism, and...

On the definition and relevance of context-awareness in Personal Networks

Personal Networks (PNs) enable users to be connected with their devices and services at any time and any place. Context-Awareness will further enrich PNs. This paper shows some examples, presents definitions of Context and Context-Awareness for PNs, and introduces a high-level architecture for Context-Awareness that is tailored to PNs.

A concrete example of a Personal Network architecture

A Personal Network (PN) is created when the various private networks of a single user are always seamlessly interconnected, despite the mobility of the user. To realize this vision we have designed an architecture of a simple, concrete example of such a PN. It consists of just a home network and a Personal Area Network (PAN), which are...

A four-tiered hierarchy in a converged fixed-mobile architecture, enabling personal networks

We present a new way of capturing the future technical infrastructure of a converged fixed-mobile infrastructure by means of a four-tiered hierarchy of one fixed and three different mobile and wireless (access) layers. With such a view, the current range of heterogeneous interconnected public and private networks can be easily modelled as a...
