Fieldwork is an important means of contextualising knowledge and developing subject-specific and generic transferable skills. However, field locations are not always accessible. To address this problem we present a remote fieldwork approach that makes use of a portable wireless network and other mobile technologies to support fieldwork at a distance. As well as improving access to fieldwork, th...

An increasing demand for higher spectral efficiencies in mobile communications will require next generation cellular systems to employ a dense reuse of spectrum in combination with smart interference mitigation or cancellation schemes. Recent publications have revealed the large potential spectral efficiency and fairness gains achievable with multi-cell cooperative schemes, where multiple base ...

This paper deals with the analysis of user perceived visual quality for mobile multimedia services. H.264/AVC is selected for low resolution video encoding, and a mobile UMTS network is considered for the access to services. First, from subjective tests results, the combined impact of different service– and radio network–level parameters is inferred. As a result, different cross–layer adaptatio...

Today’s mobile operators face significant challenges with handling the ever-increasing volume of mobile data traffic. With new mobile communication standards, like 4G/LTE, the mobile backhaul architecture has a clear split of a packet-only dataplane and a management plane. Although this new backhaul architecture yields to easier management, we find that this architecture can be improved further...

In cognitive radio networks, the channel gain between primary transceivers is crucial for a cognitive transmitter (CT) to control the transmit power and achieve the coexistence. To obtain the channel gain, a backhaul between the primary system and the CT is needed. However, the backhaul is usually unavailable in practice. To deal with this issue, the CT is enabled to sense the primary signals a...

— As demand for broadband service increases in emerging regions, high-capacity wireless links can accelerate and cost-reduce the deployment of new networks (both backhaul and customer site connection). Such links are increasingly common in developed countries, but their reliability in emerging regions is questioned where very heavy tropical rain is present. Here, we investigate the robustness o...

Intermodal transport, the combination and integration of several transport modes, with the use of loading units, is in most cases more environmentally friendly than unimodal road transport for the carriage of goods. The LAMBIT-model (Location Analysis Model for Belgian Intermodal Terminals) has been developed to analyse the market areas of existing and potential intermodal terminals. In the LAM...

This paper deals with multiuser detection through base station cooperation in an uplink interference limited, high frequency reuse scenario. Distributed iterative detection (DID) is an interference mitigation technique in which the base stations at different geographical locations exchange detected data iteratively while performing separate detection and decoding of their received data streams....

The continuous increase in mobile data traffic creates the need for radical innovations in the mobile broadband system design. Heterogeneous networks (HetNets) deployment paradigm is an emerging research trend considered as the most significant aspect for meeting the mobile data challenge, mainly by proposing spectral efficiency enhancements and cell capacity gains from an overall system perspe...

Coordinated multi-point processing at multiple base stations can improve coverage, system throughput, and cell-edge throughput for future cellular systems. In this paper, we study the coordinated reception of transmitted signals at multiple MIMO base stations to exploit cooperative diversity. In particular, we propose to employ cooperative multicell automatic repeat request (ARQ) protocol via b...
