Convergence of voice and data telecommunications transmissions

INTELEC. Twenty-Second International Telecommunications Energy Conference (Cat. No.00CH37131), 2002
Our insatiable need for instant information will continue to make telecommunication systems an increasingly integral part of our society, demanding ever more services for real-time data and, of course, reliable networks. Mobility in society is key today, and the ability to be "always connected" is crucial not only to business people, but to the general

Modeling telecommunications networks' transmission systems

IEEE Communications Magazine, 1996
The author discusses the status of synchronous digital hierarchy (SDH) management standards and related matters such as plesiochronous digital hierarchy (PDH), and offers an overview of the information contained within these standards. He provides an overview of those areas that are still under study or need further investigation by international ...

Telecommunications and data transmission

1992
The term ‘telecommunications’ is used to describe all the methods which transmit information electronically. In the UK, the national telecommunications network is supplied by British Telecom. However, other companies are now providing and competing for specialised services. For example, Mercury has established some networks and services.

Future trends in digital telecommunication transmission networks

Electronics & Communication Engineering Journal, 1990
New technology is needed by digital transmission networks for the increased bandwidth, performance and reliability requirements of existing and future telecommunication services, such as broadband ISDN. Increased flexibility, automation and control are also major issues being addressed.

Transmission Schemes For Optical Telecommunications In Space

SPIE Proceedings, 1989
A theoretical investigation on optical transmission schemes for free-space applications is carried out. Receiver sensitivity of direct detection schemes like NRZ and QPPM (quaternary pulse position modulation) are evaluated. For bit rates between 10 and 65 Mbit/s, QPPM outperforms NRZ by up to 2.0 dB.

Future trends in telecommunications transmission—a personal view

IEE Proceedings F Communications, Radar and Signal Processing, 1984
After briefly tracing transmission system development to the present day, the paper goes on to consider the likely progression of both services and technology in the near and far future. To provide a clear focus for the discussion, a number of ‘end point’ developments and targets are postulated as the ultimate objectives of the transmission engineer ...

Comparative analysis of classical and new transmission lines for telecommunication systems

2000 10th International Crimean Microwave Conference. "Microwave and Telecommunication Technology". Conference Proceedings (IEEE Cat. No.00EX415), 2000
Comparative analysis results of the main features of classical and new types of transmission lines for different telecommunication MM-wave applications, have been presented. New lines are based on flat waveguide splitters both with (EH, HE odd and even modes) and without (E odd modes only) dielectric filling.

Telecommunications and the Changing Geographies of Knowledge Transmission in the Late 20th Century

Urban Studies, 1995
Recent innovations in telecommunications and computing, enhanced by a global wave of deregulation and the emergence of post-Fordist production regimes, have unleashed profound transformations of various service sectors in the global economy. This paper first reviews the geographical repercussions of the explosion of information services, including the
