Available in PDF, EPUB and Kindle. Book excerpt: Cellular communications has become one of the fastest growing segments in the telecommunications industry. The demand for cellular services has risen beyond all expectations. With the current growth of the analog cellular network, a strain has been put on the existing system and available spectrum. Cellular providers have been forced to use the existing bandwidth more efficiently by converting to digital technology. Four major digital cellular techniques are competing for marketplace dominance and each has the ability to expand the capacity of the cellular networks. The four systems are Global System for Mobile Communications (GSM), the Pan-European standard that utilizes FDMA/ TDMA, using 25 MHz bandwidth channels, and operates in the radio frequency bands of 890-915 MHz for the uplink and 935-960 in the downlink; Digital Advanced Mobile Phone System (D-AMPS), the North American Digital Standard which is backwards compatible with the existing AMPS system; IS- 95 manufactured by Qualcomm Inc. which utilizes the newest of the technologies CDMA, and finally Personal Digital Cellular (PDC), Japan's alternative which also uses TDMA technology. It is uncertain which system will become the standard, but it is certain that the ability to get to the marketplace, dominate it, and secure a stronghold in the market will be the successful standard.

Download or read book Performance Analysis of Multi Channel and Multi Traffic on Wireless Communication Networks written by Wuyi Yue and published by Springer Science & Business Media. This book was released on 2002-02-28 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book attempts to present exact and approximate analytical solution methods and techniques using queueing theory in the complex multimedia traffic systems with procedures of random multiple access schemes. In particular, this book presents how to approximate the system performance of discrete-time multimedia networks, the probability distribution of the interarrival time of internetwork packets at the adjacent network and the higher moments of the transmission departure distribution and delay in wireless multimedia communication environment. In general the modeling of discrete-time multimedia communication systems are more complex than that of continuous-time systems because multiple state changes can occur from one time-unit to the next. This complicates the analysis of the model. This book also discusses numerical results that illustrate the applications of the theory and various properties.

Download or read book An Analysis of Regulatory Frameworks for Wireless Communications Societal Concerns and Risk written by Haim Mazar and published by Universal-Publishers. This book was released on 2009 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis analyses how and why culture and geography influence the allocation and licensing of the radio frequency (RF) spectrum in different nations. Based on a broad comparative study of 235 countries, an inter-disciplinary approach is used to explore regulatory frameworks and attitudes toward risk. In addition, detailed case studies of the UK, France, the US and Ecuador provide deeper insights into the main contrasting regulatory styles. Three alternative sociological theories are used to analyse and explain the results for both the in-depth and broad brush studies. The Cultural Theory of Mary Douglas and co-workers is first used to categorise countries in terms of perceptual filters. The empirical findings indicate some countries to be apparently exceptional in their behaviour. The theory of Bounded Rationality is used to investigate and explain these apparent irrationalities. Finally, Rational Field Theory shows how beliefs and values guide administrations in their RF regulation. A number of key factors are found to dominate and patterns emerge. The European RF harmonisation is unique. Following European unification, wireless regulation is divided into two major camps (the EU and the US), which differ in their risk concerns, approach to top-down mandated standards, allocation of RF spectrum to licence-exempt bands and type approval process. The adoption of 3G cellular (UMTS versus CDMA2000) and digital TV standards (DVB-T/ATSC/ISDB-T) around the world reflects geopolitical and colonial influence. The language of a country is a significant indicator of its analogue TV standard (SECAM/PAL/NTSC). Interestingly, the longitude of a country to a fair extent defines RF allocation: Africa and West Asia follow Europe, whereas the Americas approximate the US. RF regulation and risk tolerability differ between tropical and non-tropical climates. The collectivised/centralised versus the individualised/market-based rationalities result in different regulatory frameworks and contrasting societal and risk concerns. The success of the top-down European GSM and the bottom-up Wi-Fi standards reveal how the central-planning and market-based approaches have thrived. Attitudes to RF human hazards and spurious emissions levels reveal that the US, Canada and Japan are more tolerant of these radiation risks than Europe. Australia, Canada, New Zealand, UK and USA encourage technological innovation. A practical benefit of this study is that it will give regulators more freedom to choose a rational RF licensing protocol, by better understanding the possibly self-imposed boundaries of cultural and geographical factors which are currently shaping allocation. Academically, there is utility in undertaking a cultural and geographic analysis of a topic that is mostly the domain of engineering, economic and legal analysts.
