tion. The arrangement is chronological from pre-cellular mobile networks, through each of the generations (1G, 2G, etc.), noting how American firms dominated at first but have steadily lost headway to European and Japanese companies and providers. Looking ahead to 4G he discusses “the China card” potential. Part three reviews industry catalysts: from equipment manufacturers to enablers. Here the chapters are built around specific players: Motorola, Ericsson, Nokia (Steinbock is the author of THE NOKIA REVOLUTION [Amacom, 2001]), Qualcomm, the various contractors (“from ‘board stuffers’ to elec...

This review concludes that 3G (third-generation mobile networks) universal mobile telecommunication system (UMTS) options are fascinating and the authors are generally upbeat about the many options that the development technology makes available.

An outline of ITS in Japan is presented based on several ITS service systems such as vehicle information communication system (VICS), electronic toll collection (ETC) with dedicated short range communication (DSRC) technology.

The summer vacation scholorship by looking at loss systems gave an explicit expression for blocking probability and is also known as Erlang's Formula.

applied their own teaching experience to this. Chapters introduce professional announcing, the audio studio environment, TV and cable studios, vocal development, performance development, commercial announcing, interviewing, news announcing, music announcing (nd all of its types), sports announcing, specialty work, and beginning an announcing career. An appendix reviews ethical and legal issues for broadcast performers. Each chapter has self-study questions and answers and projects. (Chris Sterling)

A rich narrative broken into eight chapters covering different periods, beginning in 1843 (when Ada Lovelace wrote an account of Charles Babbage’s design for a programmable computing machine) through to the end of 2004, arranged by year.

This paper uses firm-level data to investigate whether digitally-enabled firms have been able to mitigate economic losses arising from the pandemic better than digitally-constrained firms in the Middle East and Central Asia region using a difference-in-differences approach, and suggests that policymakers need to close the digital gap and accelerate firms’ digital transformation.

This work examines mobile autonomous agent technology and its ability to effectively fight a computer virus attack on a network, and presents both virus propagation and virus detection algorithms, simulation details, and a discussion of the aglet test environment architecture.

Many hotel managers find telecommunications to be a little understood technology. Call-accounting equipment allows hotels to resell long-distance calls and to account for local calls. Hotel switchboards should include such features as least-cost routing and automatic call rating (pricing). Several variables can be modified to affect call placement, distribution, and pricing to improve profitability, particularly variables relating to whether the hotel uses analog or digital "trunks" (cables used to connect to the phone-service provider). Yesterday's call-accounting systems need to be reviewed ...

Off-line composition saved money and provided students the opportunity to send well-constructed messages.

A review of the current and likely future state of Internet Protocol networking and a survey of charging Internet services, IP security, and the future of the optical Internet as an integration of optical and IP technologies are discussed.

The editor, with Japan’s DoCoMo Laboratories in the U.S., divides his contributors’ chapters into four main parts: a vision for the next generation includes the evolution of mobile networks and services to this point, and the all Internet Protocol next-generation systems.

The half-century following the Civil War witnessed an epochal transformation in American telecommunications. In the 1870s, the telegraph network became a spawning ground for a remarkable spate of inventions that included the phonograph and the telephone, and around 1900 the telephone network became the first electrical communications medium that network providers intended to be accessible to the entire population. This transformation was a centerpiece of the still unprecedented burst of inventive activity that economic historians call the Second Industrial Revolution.
