This paper examines the broadband connectivity options available in digital cities. It offers an overview of services provided by commercial operators, the public sector and by citizens themselves, arguing that shortcomings in existing fixed broadband and commercial mobile broadband services provide an opportunity for citizens to share their own wireless broadband connections. It explores Wi-Fi...

The polynomial matrix EVD (PEVD) is an extension of the conventional eigenvalue decomposition (EVD) to polynomial matrices. The purpose of this article is to provide a review of the theoretical foundations of the PEVD and to highlight practical applications in the area of broadband blind source separation (BSS). Based on basic definitions of polynomial matrix terminology such as parahermitian a...

Broadband is a public utility with positive effects on competitiveness, employment and growth. Although evidence shows that broadband development is increasing, this increment is not homogeneous between urban and rural areas. The main factor is the high cost for deploying next generation networks in rural areas, and especially the cost linked to civil engineering works. In order to overcome the...

This study examines the impact of telecommunications regulatory policy on broadband service deployment. Using U.S. data covering all forms of access technology (chiefly DSL and cable modem) and all areas served by major carriers, we investigate the impact of state and federal regulation on broadband availability. Alternative regulation increases the probability of broadband availability, partic...

This paper critically assesses wireless broadband internet infrastructure, in the rural and remote communities of WDR in terms of supply, demand and utilisation. Only 8 of 20 towns have ADSL/ADSL2+, and only 3 towns have 4G mobile network coverage. Conversely all of the towns have 2G/3G mobile network coverage but have problems with speed, reliability of service and capacity to handle data traf...

Though the potential benefits of broadband Internet adoption are great, the levels of take-up vary greatly around the world. Some governments have adopted aggressive policies to deploy broadband networks and to encourage the use of these applications, while others have not. In the former cases, governments are motivated to promote broadband adoption in order to realize both economic and social ...

2 Interest in the economic impact of Information and Communication Technology (ICT) investments is growing worldwide as governments seek new ways to spur growth. Moreover, investment decisions must undergo extra scrutiny in the current tough economic conditions. In 2010, Ericsson and Arthur D. Little conducted an in-depth study titled " Socioeconomic Impact of Broadband Network Investments, " w...

1. We have examined the relationship between the attenuation of broadband ultrasound in the os calcis in vitro and its bone mineral density measured by quantitative computed tomography and by physical density. 2. Broadband ultrasound attenuation was found to correlate closely with physical density (r = 0.85, P less than 0.0001), but the correlation was less than that observed between quantitati...

Currently, non-invasive methods for studying the human brain do not routinely and reliably measure spike-rate-dependent signals, independent of responses such as hemodynamic coupling (fMRI) and subthreshold neuronal synchrony (oscillations and event-related potentials). In contrast, invasive methods-microelectrode recordings and electrocorticography (ECoG)-have recently measured broadband power...

Broadband networks are used by hundreds of millions of users to connect to the Internet today. However, most ISPs are hesitant to reveal details about their network deployments, and as a result the characteristics of broadband networks are often not known to users, developers, and researchers. In this thesis, we make progress towards mitigating this lack of transparency in broadband access netw...
