Abstract

In this paper we present an fully empirical assessment of the possibilities which are brought about by an architecture able to handle multiple wireless access technologies. Heterogeneity is believed to play a key role in forthcoming communication scenarios and therefore some entities able to appropriately tackle the new challenges are deemed necessary. Although reaching the Always Best Connected paradigm has gathered the interest of the scientific community, many of the existing works are descriptive (architectural papers) or based on simulation and/or emulation. In this paper we go a step beyond this and starting from the architecture proposed in the Mobilia Celtic project, we deploy a real platform to showcase two illustrative handover examples, triggered either by the end-user and the network. Additionally, we use the same platform to quantitatively analyze the enhancement which the use of multi-RAT devices may provide, in terms of the handover latency reduction.
