Inhaltsangabe:Abstract: This diploma thesis paper is, after contemplating the current state of ITC / telco's shift towards commoditisation and challenges in facing the upcoming overall mobile / wireless development (beyond 3G, B3G, / 4G) aimed at prosperously resolving a marketing proposition on a quite ingenious Siemens mobile P2P communication solution, named Siemens Anyw@re PocketSERVent, by virtue of the marketers' generic means, the Product-marketing mix dedicated to fundamental questions of product, price, promotion, place (P4). Strategic marketing and ITC business as well as down-to-earth / operational themes will get propelled. The chief emphasis is put on surging virtualisation related to product / svce / property and, as usually less exposed, the shift towards intangible values, foremost customer relationship and momentum of the hi-tech. brand (perception). The intend is to supply a big yet detailed P2P, 3G / B3G and wireless picture to the marketer (even accountant) as well as applied marketing / pricing issues to the S/W developer or mobile techn. expert. After a brief overview (ch. 1), chapter 2 is about introducing the main points rel. peer-to-peer (P2P) it's rather social impacts, technological mindset and ongoing research, as well as contemporary benefits. The intention is to free both the subject and evaluation from hype or byzantine aspects; to present P2P's potential as well as existent contributions to corporations aware of bus. value from IT, parelleling the fashion well-known IT players dominate e.g. Web services. Chapter 3 prepares a general understanding of present-day and forthcoming ITC leitmotivs, more precisely, for why ITC, esp. 3G innovations, have been disappointing. Analysing soft product and service (svce / svc.) innovations is upon hard value; at the dawn of this decade's decentralisation / mobilisation and virtualisation following results and side effects of globalisation the tractate's author is going to constantly question whether proven and established marketing practice can answer the train of virtual i.e. through-and-through digital products, value chains, organisations or business and / or value creation communities. Nevertheless ch. 3's focal point is the wireless or mobile wireless, resp., upgrowth (convergence rel. mobile IP, P2P, B3G / 4G). At beginning of the new millennium telcos are forced to get out of the industrial age's proprietary hardware and services. Less because of customer's [...]

You’ll then dive into performance characteristics of technologies such as HTTP 2.0, client-side network scripting with XHR, real-time streaming with SSE and WebSocket, and P2P communication with WebRTC. Deliver superlative TCP, UDP, and TLS performance Speed up network performance over 3G/4G mobile networks Develop fast and energy-efficient mobile applications Address bottlenecks in HTTP 1.x and other browser protocols Plan for and deliver the best HTTP 2.0 performance Enable efficient real-time streaming in the browser Create efficient peer-to-peer videoconferencing and low-latency applications with real-time WebRTC transports

Programming has become a significant part of connecting theoretical development and scientific application computation. Computer programs and processes that take into account the goals and needs of the user meet with the greatest success, so it behooves software engineers to consider the human element inherent in every line of code they write. Research Anthology on Recent Trends, Tools, and Implications of Computer Programming is a vital reference source that examines the latest scholarly material on trends, techniques, and uses of various programming applications and examines the benefits and challenges of these computational developments. Highlighting a range of topics such as coding standards, software engineering, and computer systems development, this multi-volume book is ideally designed for programmers, computer scientists, software developers, analysts, security experts, IoT software programmers, computer and software engineers, students, professionals, and researchers.

The key feature of future mobile communication systems is the ability to deliver wideband and high bit-rate multimedia services alongside the traditional radio services such as voice, messaging and slow rate data. The broad range of services expected to be supported can be divided into different Quality of Service (QoS) classes. However, the provision of such mobile multimedia services under QoS guarantees will not be possible without a utilization of the air interface resources by means of Radio Resource Management (RRM) strategies that ensure the target QoS, the planned coverage area and that offer a high system capacity. Under this framework, the book focuses on the RRM concepts, including the theoretical background that serves as a basis for the description of specific RRM algorithms. The RRM problem for UMTS is presented, and more specifically, for the FDD mode, which is based on a WCDMA scheme. More specifically, the different aspects that are covered include: Introduces the mobile communications sector and UMTS, including the evolution towards 4G systems, with an overview of the QoS concept which is key for the definition of RRM strategies Offers a detailed description of the radio interface in UMTS, as the basis for the implementation of RRM strategies Provides the fundamental concepts related with the development of RRM strategies in WCDMA networks Analyses particular RRM algorithms in a variety of scenarios, trying to identify the key parameters and factors that influence their performance Explores the evolution of UMTS towards Beyond 3G systems and the concept of Common RRM in heterogeneous networks with the aid of some algorithm examples This comprehensive title is essential reading for engineers and managers in radio engineering departments of UMTS network operators and UMTS equipment manufacturers. It will also prove insightful to researchers in the field of 3G and Beyond 3G systems and academics in any of these areas.

A highly practical guide rooted in theory to include the necessary background for taking the reader through the planning, implementation and management stages for each type of cellular network. Present day cellular networks are a mixture of the technologies like GSM, EGPRS and WCDMA. They even contain features of the technologies that will lead us to the fourth generation networks. Designing and optimising these complex networks requires much deeper understanding. Advanced Cellular Network Planning and Optimisation presents radio, transmission and core network planning and optimisation aspects for GSM, EGPRS and WCDMA networks with focus on practical aspects of the field. Experts from each of the domains have brought their experiences under one book making it an essential read for design practitioners, experts, scientists and students working in the cellular industry. Key Highlights Focus on radio, transmission and core network planning and optimisation Covers GSM, EGPRS, WCDMA network planning & optimisation Gives an introduction to the networks/technologies beyond WCDMA, and explores its current status and future potential Examines the full range of potential scenarios and problems faced by those who design cellular networks and provides advice and solutions all backed up with real-world examples This text will serve as a handbook to anyone engaged in the design, deployment, performance and business of Cellular Networks. "Efficient planning and optimization of mobile networks are key to guarantee superior quality of service and user experience. They also form the essential foundation for the success of future technology development, making this book a valuable read on the road towards 4G." —Tero Ojanperä, Chief Technology Officer, Nokia Networks
