The wireless telephone industry has seen dramatic changes. In the United States, for example, cellular demand continues to increase with high annual growth rates. In order to help meet this demand and to promote competition in the duopolistic wireless telephone industry, the Federal Communications Commission (FCC) supplemented the existing cellular industry capacity by auctioning spectrum for p...

Cellular frequency reuse is known to be an efficient method to allow many wireless telephone subscribers to share the same frequency band. However, for wireless data and multi-media communications optimum cell layouts differ essentially from typical solutions for telephone systems. We argue that wireless radio systems for bursty message traffic preferably use the entire bandwidth in each cell. ...

Proficiency in client communications is now widely accepted as a significant requirement of veterinary student education, with numerous training systems use and documentation outcomes required for academic accreditation. Little information available concerning communication house officers (interns residents), despite the large number new graduates who enter such programs seeking further mentors...

Current industrial processes often involve the collaboration of people at distant and remote locations. The technological media for such a tele-cooperation reach from simple email or text-based chatting systems to highly-sophisticated systems for an interactive video-conferencing. But with limited bandwidth the communication between persons at distant locations is often restricted to single mod...

Telephone technology is a technology that stands the test of time. Since it was invented in 1876 by Alexander Graham Belle, it has remained the technology of all time. This article reports the major findings of a recent research, ‘How Technology Transforms Citizen Journalism Business in Nigeria’. According to the research, Telephone technology has over the years emerged a major tool with which ...

This article examines how asset-light operations create competitive advantage in the telephone communications industry. Competitive advantage is defined as the ability of a firm to generate returns above its synthetic normal return. Three regression models are developed to describe the relationships between asset-light operations and competitive advantage. This empirical study provides several ...

The Subscriber Identity Module (SIM) is conventionally used in wireless communication systems. However, several limitations involving SIM significantly reduce public access in wireless communications. This study examined the feasibility of using public telephone cards in wireless communications. This novel application retains the merits of SIM. Among the relevent issues addressed are location t...

The spectre of low-cost, real-time voice communication over the Internet has polarised Internet service providers and telephone network operators, at the expense of finding solutions to the problem of integrating communications services (in particular, existing wireless and wireline telephony) with WWW content services. This paper argues that such solutions not only exist and appear to be comme...

As the amount of spoken communications accessible by computers increases, searching and browsing is becoming crucial for utilizing such material for gathering information. It is desirable for multimedia content analysis systems to handle various formats of data and to serve varying user needs while presenting a simple and consistent user interface. In this paper, we present a research system fo...

Although the conventional concept of communication is the exchange of logical information, the exchange of Kansei has become very important recently, especially in the case of mobile telephone communications. In addition, it has been recognized that the use of the body, such as facial expressions and gestures, is essential in communications. These facts indicate that technologies that can suppo...
