Mobile Small Cells: Broadband Access Solution for Public Transport Users

The increasing popularity and usage of portable smart devices have heightened the demand for higher data rates and mobility support in wireless communication networks. Many portable device users rely heavily on public transport during their trips to work, school, and other business locations. To facilitate the provision of high data rates for these commuters, the development of innovative wireless technologies is critical. Small cell networks can be a promising solution to this challenge. However, incorporating small cells in vehicular environments demands further investigation, especially for issues related to their communication architecture, interference and resource management. In this article, we present a small cell network system design that can provide seamless high data rate services to public transport users. We address the frequency allocation problem for mobile small cells and introduce time-varying frequency allocation solutions to meet the dynamic network topology and varying user traffic requirements.

Para-social relationships and continuous use of mobile devices

Comprehending factors that affect customer satisfaction and continued usage of mobile devices become more important as their prevalence and turnover increase. In this study, socio-relational forces such as para-social relationships PSRs are examined in an effort to explain behaviours of users of mobile systems. The results indicated that traditional success factors must be complemented by socio-relational forces such as PSR. Very strong associations were identified between social bonds, user attitudes and usage continuance. The user interface design of a mobile device was shown to shape the relational attitudes of users. Understanding behaviours of users of portable devices requires a perspective different from those applied in traditional enterprise-level information systems ISs settings.

The use and risk of portable electronic devices while cycling among different age groups

Introduction: In the Netherlands, a survey was set up to monitor the extent of the use of portable, electronic devices while cycling amongst different age groups of cyclists and to estimate the possible consequences for safety. Method: The main research questions concerned age differences in the self-reported use of electronic devices while cycling, self-reported crash involvement and risk, and self-reported compensatory behaviour. Teen cyclists (12–17years) and young adult cyclists (18–34years) were more frequent users, and also more indiscriminate users of portable devices while cycling than middle-aged and older adult cyclists (35–49years; 50+ years). Results: After statistical correction for influences on crash risk of urbanization level, weekly time spent cycling, and cycling in more demanding traffic situations, the odds of being involved in a bicycle crash were estimated to be higher for teen cyclists and young adult cyclists who used electronic devices on every trip compared to same age groups cyclists who never used these devices. For middle-aged and older adult cyclists, the use of portable electronic devices was not a significant predictor of bicycle crashes, but frequency of cycling in demanding traffic situations was. Possible implications for education or legal measures are discussed. Impact on Industry: Results may inform researchers, policy makers, and cyclists themselves. Educational campaigns may use risk information to warn young cyclists about risk of device use while cycling.
