Obsea: a decadal balance for a cabled observatory deployment

The study of the effects of climate change on the marine environment requires the existence of sufficiently long time series of key parameters. The study of these series allows both to characterize the range of variability in each particular region and to detect trends or changes that could be attributed to anthropogenic causes. For this reason, networks of permanent cabled observation systems are being deployed in the ocean. This paper presents a balance of a decade of activity at the OBSEA cabled observatory, as an example of ocean monitoring success and drawbacks. It is not the objective of this article to analyze the scientific and technical aspects already presented by the authors in different publications (Table 4). We will evaluate the overall experience by retracing the different steps of infrastructure deployment and maintenance, focusing on routines for in situ control, damages experienced, breakdowns and administrative constraints by local administrations. We will conclude by providing a set of guidelines to improve cabled observatories scientific outreach, societal projection, and economic efficiency. As a result of this work, a 10-years dataset has been published in Pangaea that is available for the community.Peer ReviewedPostprint (published version

Sanchari: Moving Up the Value Chain Through Telecommunication Services

The year 2009 was a critical year in the development of Sanchari, a state-owned telecommunication infrastructure (TI) service provider in India. Over the past few years, Sanchari had successfully developed and delivered on-demand infrastructure services to customers in the state of Karnataka, India. Sanchari’s management team wanted to move their business up the value chain to take advantage of the rapidly growing telecommunication industry in India. In the middle of 2009, Sanchari was approached by the state government of Karnataka to lead the development of a state-wide-area-network (SWAN) under the e-government initiative. This e-government project could give Sanchari an opportunity to move up the value chain. Sanchari needed to decide whether it would take the sole responsibility of this project as the government agent or form a partnership with a private company to execute it. This decision, however, would depend on whether Sanchari wanted to develop into an infrastructure or software service provider or maintain its status quo as a TI service provider in the long term. The teaching case provides a challenging decision-making situation for students and urges them to analyze the benefits and risks of moving up the telecommunication value chain

Towards the energy transition: strong HV orders intake driving prysmian’s destiny

Arctic subsea communication cables and the regional development of northern peripheries

Some years ago, the Arctic Ocean was still described as one of the last oceans that did not have subsea communications cables across it. This situation is now changing. One of the greatest increases in global data transfer is predicted to be traffic between Asia and Europe, and the Arctic Ocean offers a shortcut, making physical cable connections shorter and decreasing latency. Recent developments regarding two ongoing subsea communications cable projects (Quintillion and Arctic Connect), which aim to connect East Asia and Europe, are discussed, and the connection between these projects and regional development policies in Hokkaido and northern Finland are analysed. It is shown that the proposition that improved international connectivity through subsea communications cables could bring information-intensive industries into the region had been stronger in Finland. This is largely due to a lack of information and awareness concerning these projects among the regional actors in Hokkaido; however, no concrete policy or funding instrument has been developed in either of the case regions

Economically sustainable public security and emergency network exploiting a broadband communications satellite

The research contributes to work in Rapid Deployment of a National Public Security and Emergency Communications Network using Communication Satellite Broadband. Although studies in Public Security Communication networks have examined the use of communications satellite as an integral part of the Communication Infrastructure, there has not been an in-depth design analysis of an optimized regional broadband-based communication satellite in relation to the envisaged service coverage area, with little or no terrestrial last-mile telecommunications infrastructure for delivery of satellite solutions, applications and services. As such, the research provides a case study of a Nigerian Public Safety Security Communications Pilot project deployed in regions of the African continent with inadequate terrestrial last mile infrastructure and thus requiring a robust regional Communications Satellite complemented with variants of terrestrial wireless technologies to bridge the digital hiatus as a short and medium term measure apart from other strategic needs. The research not only addresses the pivotal role of a secured integrated communications Public safety network for security agencies and emergency service organizations with its potential to foster efficient information symmetry amongst their operations including during emergency and crisis management in a timely manner but demonstrates a working model of how analogue spectrum meant for Push-to-Talk (PTT) services can be re-farmed and digitalized as a “dedicated” broadband-based public communications system. The network’s sustainability can be secured by using excess capacity for the strategic commercial telecommunication needs of the state and its citizens. Utilization of scarce spectrum has been deployed for Nigeria’s Cashless policy pilot project for financial and digital inclusion. This effectively drives the universal access goals, without exclusivity, in a continent, which still remains the least wired in the world

Information and Control: Inventing the Communications Revolution in Post-War Britain

This thesis undertakes the first history of the post-war British telephone system, and addresses it through the lens of both actors’ and analysts’ emphases on the importance of ‘information’ and ‘control’. I explore both through a range of chapters on organisational history, laboratories, telephone exchanges, transmission technologies, futurology, transatlantic communications, and privatisation. The ideal of an ‘information network’ or an ‘information age’ is present to varying extents in all these chapters, as are deployments of different forms of control. The most pervasive, and controversial, form of control throughout this history is computer control, but I show that other forms of control, including environmental, spatial, and temporal, are all also important. I make three arguments: first, that the technological characteristics of the telephone system meant that its liberalisation and privatisation were much more ambiguous for competition and monopoly than expected; second, that information has been more important to the telephone system as an ideal to strive for, rather than the telephone system’s contribution to creating an apparent information age; third, that control is a more useful concept than information for analysing the history of the telephone system, but more work is needed to study the discursive significance of ‘control’ itself
