Abstract

Set in September 1992, this exercise provides teams of students the opportunity to negotiate terms of a merger between AT&T and McCaw Cellular. AT&T, one of the largest U.S. corporations, was the dominant competitor in long-distance telephone communications in the United States. McCaw was the largest competitor in the rapidly growing cellular-telephone communications industry. Prior to the negotiations, AT&T had no position in cellular communications. This case and its companion (F-1143) are designed to allow students to be assigned roles to play. The case may pursue some or all of the following teaching objectives: exercising valuation skills, practicing strategic analysis, exercising bargaining skills, and illustrating practical aspects of mergers and acquisitions.

Abstract

This article examines the dynamics of wireless R&D as a combined function of technology and market evolution, focusing on the management and organization of wireless R&D. From the postwar era to the late 1990s, the management and organization of wireless R&D capabilities has been effectively reversed. Industry thrust has shifted from closed specifications, central innovation and domestic market to open specifications, distributed innovation and global networking. The old era is reflected by the classic Bell Labs; the new era by Nokia. Due to the alternation of sustaining and disruptive change, no wireless company can survive without incessant innovation. In this rivalry, the winners are companies that best match their organizational capabilities with the changing industry opportunities.

Abstract

Illinois Superconductor Corp. a technology start-up, came up with an innovative new superconducting filter for use in cellular base stations. It needed to estimate the demand for its filters. The manager came up with a simple chain-ratio-based forecasting model that, while simple and intuitive, was too simplistic. The company had also commissioned a research firm to develop a model-based forecast. The model-based forecast used diffusion modeling, analogy-based forecasting, and conjoint analysis to create a forecast that incorporated customer preferences, diffusion effects, and competitive dynamics.

To use the data to generate a model-based forecast and to reconcile the model-based forecast with the manager's forecast. Requires sophisticated spreadsheet modeling and the application of advanced forecasting techniques.

Abstract

Focuses on Dancall A/S, a Danish telecommunications equipment manufacturer, which was acquired by Amstrad UK in September 1993 for £6.4 million. As an independent subsidiary of Amstrad UK, Dancall is in a position to develop its marketing strategy to a mass UK market. Suggests that heuristic devices could be the way to proceed in its tactical application of the strategic plan.

Communication of an impending hazard to people in near real time is critical. The purpose of this paper is to develop an internet‐SMS based geo‐hazard warning communication system.

Abstract

Purpose

Communication of an impending hazard to people in near real time is critical. The purpose of this paper is to develop an internet‐SMS based geo‐hazard warning communication system.

Design/methodology/approach

A warning system based on an internet‐resident concept and the available cellular mobile infrastructure is proposed in this study. The functionality of the system is modular in architecture.

Findings

The messages have been transmitted in a set of 20 SMSs six times, to locally‐owned mobile numbers, resulting in a total number of 120. It has been found that 58 messages got delivered within ten seconds, the rest within 40 more seconds. The threat messages reached the impending threat areas within acceptable time delay.

Originality/value

The paper describes the implementation of a novel and stand‐alone system for dynamic hazard warning. Cellular or mobile phone, a gadget used by common man, is expected to be the best proposition to effectively warn people individually and to propagate hazard messages to users in large regions ubiquitously. The concept allows pervasiveness and redundancy, important to withstanding hazards and bringing several original elements through the development of this “fast warning system”, as current warning strategies do not include such solutions.

Abstract

Low‐level microwave (MW) fields may under certain conditions of exposure cause measurable effects in biological organisms. Exposure of the general public to MWs in the environment is generally below intensities which are considered as responsible for evoking bioeffects. Introduction of cellular phone (CP) systems has increased considerably MW exposure of CP users. Health consequences of long‐term use of CPs are not known in detail, but available data indicate that development of non‐specific health symptoms is possible, at least in “MW hypersensitive” subjects. In contrast to terminal CPs, transmitting antennas and base stations (BS) contribute to MW environmental contamination only with a small portion of the energy and do not pose any health risks. Health risks of CP use are underestimated and accepted, while risks of BS are generally overestimated by the public. Therefore, an improved risk communication as well as further studies of the risks are required.

Abstract

Nomadicity is a new challenge for computing and communication technologies. Modern cellular telephone systems extend the usability of portable personal computers enormously. A nomadic user can be given ubiquitous access to remote information stores and computing services. However, the behaviour of wireless links creates severe inconveniences within the traditional data communication paradigm. In this paper we give an overview of the problems related to wireless mobility. We also present a new software architecture for mastering the problems and discuss a new paradigm for designing mobile distributed applications. The key idea in the architecture is to place a mediator, a distributed intelligent agent, between the mobile node and the wireline network.

Abstract

‘Even in the very few instances where the accused has intrusted his defender with a full confession of his crime, we hold it to be clear that he may still be lawfully defended. The guilt of which he may be conscious, and which he may have so disclosed, he has still a right to see distinctly proved upon him by legal evidence … Human beings are never to be run down like beasts of prey, without respect to the laws of the chase.’

Abstract

In the hectic world in which we live it is all too easy to lose sight of our original goals. Day‐to‐day events take on an unprecedented amount of importance relative to our overall aims. What people need more of is an overview of what they are doing to enable clarity and perspective to shine through. Easier said than done, I hear you say, and you are probably right. This special issue of British Food Journal, on the theme of new product development, aims to add perspective by adding a selection of articles on how other industries manage this most important of areas.
