Abstract

Purpose

The purpose of this paper is to build possible future scenarios for indoor connectivity in a venue such as a university campus and build alternative value network configurations (VNCs) defining different local network deployment options, focused on the Finnish telecom market.

Design/methodology/approach

In this paper, Schoemaker’s scenario planning method (Schoemaker, 1995) is used to construct future scenarios and the VNC method of Casey et al. (2010) is used to build alternative VNCs. The paper studies the Aalto University campus network for current end-user data usage demand and the existing technology used in meeting the end-user needs and forecasts the demand for the next five years to understand the need for 5G.

Findings

This research concludes that with the provision of local spectrum licenses, there is an opportunity for venue owners to take the role of 5G local operator on the venue premises. Furthermore, it enables venue owners to collaborate with the incumbent mobile network operators (MNOs) in a neutral host model and provide venue-specific connectivity services.

Research limitations/implications

A detailed economic assessment for the network deployment in the campus is considered for future study.

Originality/value

Considering the provision for local spectrum licenses, this paper has taken a unique attempt in identifying the future scenarios for local 5G network operations. It provides a strategic direction for the venue owners in adopting 5G technology and whether to make 5G or buy 5G from MNOs.

Abstract

Leicester Polytechnic Library uses two types of local area network (LAN). The library is connected to the polytechnic campus Cambridge Ring network which allows data communications within the library, throughout the polytechnic sites and with the wide area network. The library provides various services including an OPAC on this polytechnic network. A second LAN, a 3COM Ethernet, is used for a research project investigating the development of a decision support system on networked microcomputers. This article gives the background to these developments, provides a brief summary of local area networking and describes the network configurations implemented.

Abstract

Purpose

The development of a local area supply chain network (LASCaN) is only as good as the skills and technological capabilities of the companies within that network. Recent studies have pointed to the lack of capability amongst local suppliers and hence many OEMs have now moved towards global supplier networks to meet demand. The purpose of this paper is to highlight the drivers which push companies to develop global supplier networks.

Design/methodology/approach

Through the development of a case study approach, the paper chronicles the design, development and implementation of a supplier development programme (SDP). The programme is subsequently evaluated for its effectiveness in the subject company.

Findings

The LASCaN is evaluated rigorously and describes accurately the effectiveness of the system and how the integration of the LASCaN into the global network allows the company to meet the demands of a fluctuating, mass customised market.

Originality/value

The proposed SDP framework for the successful development of a LASCaN contributes to the existing knowledge base on supply chain systems and subsequently disseminates this information in order to provide impetus, guidance and support towards increasing the development of local suppliers in an attempt to move the UK SME sector towards world class manufacturing performance.

Abstract

Notes how rapid urbanization is transforming the developing world – creating cities, which on the one hand offer opportunities for global economic activity, but on the other hand are beset with serious local civic, economic and social problems. New networks based on information and communication technologies are increasingly being woven into the fabric of these cities supporting the connectedness of powerful groups both within the city and between cities around the world. These flows of global information and communication between powerful groups in the city involved in global economic activity coexist with intense face‐to‐face interactions at the local level. Bangalore in South India presents a major case study of this global/local interaction, being a focal point for software development in the Asian region and globally, but also beset with local problems of civic deficiencies, growing poverty and income inequality. Explores some of the issues which arise as Bangalore serves as a nexus that links global and local networks of exchange. Examines two Bangalore networks which typify global and local duality: the network of software firms located in high technology enclaves in and around the city, and the ostracised network of the slum dwellers of Bangalore, gradually being brought into mainstream discussions of governance in the city. Finds considerable similarities between global networks and local networks and outlines some of these dynamics.

Abstract

Over the past eight years, the MELVYL catalog has become one of the largest public access catalogs in the world, and now plays a central role in providing access to the library resources of the University of California. Currently, under heavy load, the MELVYL catalog supports many hundreds of simultaneous terminal connections, servicing over a quarter of a million queries a week and displaying more than two million records a week to its user community. This article discusses the history of the network that has supported the MELVYL catalog from the early days of its prototype to the present. It also describes both the current technical and policy issues that must be addressed as the network moves into the 1990s, and the roles that the network is coming to play in integrating local automation, the union catalog, access to resource databases, and other initiatives. Sidebars discuss the TCP/IP protocol suite, internet protocol gateways, and Telenet and related inter‐operability problems.

Abstract

Purpose

Mobile data traffic globally is increasing rapidly in both enterprise and consumer segments. The purpose of this paper is to identify a new network architecture and opportunity that support ubiquitous mobile work for higher-education institutions.

Design/methodology/approach

It reviews existing literature and enabling technologies and proposes integrating both wide-area Long Term Evolution-Advanced (LTE-Advanced) and local-area IEEE 802.11ac networks for seamless, gigabit-speed services. A decision framework for moving toward such architecture and a cost/benefit analysis are also presented.

Findings

Integrating both LTE-Advanced and IEEE 802.11ac networks for seamless connectivity is technically and organizationally feasible, provided that a higher-education institution has faculty and staff that require locational and interactional mobility. The cost/benefit analysis also shows that moving to the new architecture has potential benefits that can accrue to the higher-education institution.

Research limitations/implications

With the coming availability of these wide-area and local-area gigabit networks, a new architecture that can ubiquitously supports mobile workers may be advantageous to universities and colleges.

Originality/value

To the best of the authors’ knowledge, this paper is one of the first that proposes such integrated architecture in the context of higher-education institutions. In addition to the examination of technological issues and proposed architecture, the decision framework, and cost/benefit analysis should be valuable for institutions contemplating the move toward the new architecture and for guiding further research in this area.

Abstract

Information systems auditors continue to encounter a proliferation of technologies demanding their attention and expanding the scope of their audit activities. The auditor faces the problem of management expecting adequate audit coverage even though it is impossible to be an expert in all technologies, and even though audit resources are not increasing at the same rate as audit areas. The local area network (LAN) is an example of just such a technology that manifests this three‐pronged problem. Few auditors are technically equipped to audit this area comprehensively yet these networks do pose risks and should be subject to audit. At the same time, new and specialized audit resources, in many cases, are not forthcoming. Discusses some basic aspects of LAN technology having audit and control impact, internal control as it applies to LANs, and presents ideas for auditing this area keeping in mind the realities of what is possible and practical for the auditor. Does not aim to provide a definitive audit approach, but puts forward ideas to stimulate and assist information systems auditors in formulating their own specific approach to LAN audits.

Abstract

Topography is a problem in West Virginia. “If you took all the mountains of West Virginia and made them flat, West Virginia would be larger than Texas” is our boast and our network curse. Those mountains provide spectacular views, and stunning areas for our citizens who wish to maintain their independence. Those mountains and that remoteness also create difficulties in information equity, which we are just beginning to address.
