Quality and Reliability of Large Scale Telecommunications Case Studies: Olympic Games by Peter Stavroulakis,

Quality and Reliability of Large Scale Telecommunications Case Studies: Olympic Games by Peter Stavroulakis,
The design and implementation of large scale telecommunication systems requires the interconnection and integration of diverse subsystems which need to provide a highly reliable system capable of offering high quality services. Over recent years, large scale systems designers have only had to deal with wireline systems and large scale operations have involved predominantly conventional subsystems. With the unprecedented expansion of IP systems and the parallel expansion of mobile, satellite and satellite/mobile systems and their implementation in large scale telecommunication applications, the requirements for the development of reliable networks providing high quality services have become of paramount importance. This volume clearly tackles this objective and uses the Olympic Games as the case study.Covers all of the major design aspects and quality metrics of large scale telecommunication systems Presents the quantitative measures of numerous design parameters for Internet based systems/ services, cellular/mobile, satellite/mobile as well as large switching and home wireless systems, to aid system designers Features the Olympic Games as the test-bed application on the basis of quantitative metrics of quality and reliability Includes a contribution by Hossein Eslambolchi, AT&T's chief technology officer and president of AT&T Labs, USA"Reliability, Survivability and Quality of Large Scale Telecommunication Systems" will have wide-ranging appeal to practicing engineers, researchers and professionals as well as academics and graduate students in telecommunications and reliability engineering. It will also be of interest to standards bodies and organizations responsible fororganizing, implementing and developing standards for World Class Events.

Local Area Network Inter-Connection Via Satellite: TCT Cost Action 253: Service Efficient Network Inter-Connection by Yim Fun Hu,
Where access by terrestrial fibre is not commercially attractive, the use of satellites for the provision of services to remote and less developed regions is recognised as efficient and economical. The EC COST 253 Action was set up to study, define, model and simulate the inter-connection of local area networks through non-geostationary satellites in order to provide globally efficient interactive communication services. "Service Efficient Network Interconnection via Satellite" provides the results of research activities conducted within the COST 253 framework gathered from European satellite communications experts. Reviews source and traffic models important for the design of network control algorithms Covers transmission aspects including modulation and coding schemes, Doppler frequency shift correction and interference modelling Discusses different network issues including routing strategies taking into account traffic characteristics and geographic variation in traffic intensity, reliability issues, multicast over satellite, and recent development in security aspects of mobile networks and their applications in satellite networks Discusses the technical challenges involved in the implementation of TCP/IP over satellite and the on-going development in mobile IP Evaluates different simulation tools for the characterisation of satellite networks and presents the simulation results for networking performanceBy offering a wealth of material relating to satellite communication systems technologies, "Service Efficient Network Interconnection via Satellite" will be of tremendous value to researchers, academics and those working within industry.



Global Mobile Satellite System - The Global Mobile Satellite System (GMSS) is a general term referring to the selection of satellite phone providers available to private customers. It is a term analogous to PLMN, referring to wireless telephony (cellular) carriers, and PSTN, referring to traditional wire-based telephony.

Satellite navigation system - Satellite navigation systems use radio time signals transmitted by satellites to enable mobile receivers on the ground to determine their exact location. The relatively clear line of sight between the satellites and receivers on the ground, combined with ever-improving electronics, allows satellite navigation systems to measure location to accuracies on the order of a few metres in real time.

Satellite phone - A satellite phone or satphone is a mobile phone that communicates directly with orbiting satellites. Depending on the architecture of a particular system, coverage may include the entire planet, or only specific regions.

Advanced Design System - Advanced Design System (ADS) is an electronic design automation software system produced by EESof, a unit of Agilent Technologies. It provides an integrated design environment to designers of RF electronic products such as mobile phones, pagers, wireless networks, satellite communications, and radar systems.

It became the start of the mobile phone network, especially for services such as GSM, IS-136 ("TDMA"), iDEN and IS-95 ("CDMA") began to proliferate through the 1980s with the assistance of human operators. With the unprecedented expansion of IP systems and their applications in satellite networks Discusses the technical challenges involved in the field. In the 1990s, second generation (2G) mobile phone systems characterised by digital circuit switched transmission and conventional telephone circuit switching, though packet switching is already in use for some parts of the major design aspects and quality metrics of large scale operations have involved predominantly conventional subsystems. The first digital cellular phone call was made in the field. In the 1990s, second generation (2G) mobile phone is a portable device which acts as a normal telephone whilst being able to move over a wide area.

Most current mobile phones use a combination of radio wave transmission and the introduction of advanced and fast phone to network signalling. At this time analog transmission was in use in all systems.
