  • Radiowave propagation building databases and gis anything in common a Radio Engineer s viewpoint
    Environment and Planning B-planning & Design, 2003
    Co-Authors: Jeanfra Da Ric Wagen, Karim Rizk
    Abstract:

    Mobile cellular communication has already entered the mass market, and mobile Internet services will soon become a reality. The frequent use of mobile Radio technologies wherever people are has a direct impact on the deployment of base stations or Radio access points, including antennas. Put simply, to serve an increasing number of users requires an increasing number of base stations. Thus, operators must carefully plan the deployment and configurations of Radio base stations in order to support voice and data traffic at a level of quality expected by customers. Planning tools are used to help Radio Engineers in their difficult tasks of balancing requirements or Radio coverage and quality with economic and other practical aspects. These planning tools make extensive use of terrain databases and of visualisation tools that lead some tool vendors to offer functionalities very similar to a geographical information system (GIS) or even to base their product on a GIS. Futhermore, because Radio communication between base stations and users is crucial, all computations in a planning tool are based on the use of Radio-propagation predictions. Until recently, empirical propagation prediction seemed sufficient. However, more efficient planning and the planning of nonvoice services or of a mixture of voice and nonvoice services require more accurate propagation-prediction models. These propagation models are usually based on the computation of the physical interaction of ratio waves and the environment. Thus more detailed databases are required, especially in urban environments where most users are located. Although the authors are not GIS specialists, they aim to expose some of the relationship between Radio-propagation models used for mobile Radio network planning and databases for terrain and buildings. For example, an accuracy of about 1 m on the coordinates of building corners is found to be acceptable in terms of accuracy in Radio coverage. As another example, simulation results show that the use of conventional propagation models and rough geographical databases for the planning of future cellular systems like UMTS might cause serious difficulties.

  • Services for UMTS: Creating Killer Applications in 3G - Services for UMTS: Creating Killer Applications in 3G
    2002
    Co-Authors: Tomi T. Ahonen, Joe Barrett
    Abstract:

    From the Publisher: "This book is a must read if you want to understand options, future services and dream about them from a rock solid standpoint." —Roberto Saracco, Director, Future Centre, Telecom Italia Lab "This book should help telecom operators, equipment manufacturers, content providers and the capital markets manage their $1 trillion bet on the success of 3G." —Assaad Razzouk, Deputy Head of Global Corp Finance, Nomura International plc "The authors provide an insightful discussion into a wealth of service possibilities that could be delivered by UMTS." —Dr Stanley Chia, Director, Group R&D - US, Vodafone "A welcome change from the technology-led literature, Service for UMTS focuses on the services and applications end of the mobile multimedia world." —Dr Didier Bonnet, Global Head of Strategic and Business Consulting, Telecom and Media Practice, Cap Gemini Ernst & Young "This book explains some of the compelling services the players in the wireless industry will be able to develop and deploy based on the 3G and 4G infrastructure." —Jeff Lawrence, Director of Technology, Intel "This is certainly the most comprehensive work I have seen on the subject. The book explains how varous elements of technology, product development and system integration have come together to build successful 3G services." —Regina Nilsson, Director, Telecom Practice, PwC Consulting, Northern Business Unit UMTS is not about technology, it's about Services... The UMTS (Universal Mobile Telecommunications System) or 3G (3rd Generation mobile networks) environment is the ultimate convergence of fixed and mobile, voice and data, content and delivery. The result is the largest, and most complex communications system that man has designed. The industry is expected to generate revenues in excess of a trillion dollars in less than ten years. If you want a challenge, then this is the industry to be in. Services for UMTS is about the near future, where UMTS allows mobile phones and other devices for communications, entertainment, personalised services, utility and fun to be used in new ways. While it is difficult to predict the future in a precise way, broad categories and general service ideas are emerging. This volume looks at over 200 of these possible applications and provides more detailed scenarios on over 170 of them. It explores these ideas in depth, with suggestions on how to create exciting and viable services for a new world. Written for the non-technical reader and with a strong business focus, Services for UMTS is a "must-read" for anybody wanting to enter the UMTS environment, to understand it, or to make money in it. Services for UMTS intends to answer many of the current UMTS service questions as well as introduce new ideas and concepts to enable operators to create a winning UMTS services strategy. What should be the focus of service creation for rapid profits in UMTS What are the key segments that should be addressed with UMTS services What are the roles of the network operator, service provider, application developer, system integrator, and others in partnership How to build more value into digital services to turn them into killer applications for their target segments What are the differentiating factors that will separate the leaders from the UMTS pack How the new Mobile Internet differs from the existing fixed Internet, and why users, content and revenues will migrate to the Mobile Internet The 5 M's of creating desirable and profitable UMTS service Author Biography: Tomi is an independent consultant on 3G strategy. Previously he set up and headed Nokia's Global 3G Business Consultancy department. Earlier he worked for three operators/carriers in Finland and New York, creating the world's first fixed-mobile service bundle, and setting a world record for challenger operator market share, as well as participating in telecoms standardization. He started work as a controller on Wall Street. Tomi holds an MBA from St John's University New York. Joe has been in the telecommunications industry since 1979 when he joined BT. He has worked in the mobile telecommunications arena since 1985 where he worked in the emerging European mobile phone market. He has been with Nokia for over 10 years holding various positions in sales, marketing and strategic areas for the mobile infrastructure business. He started his career in the Royal Navy as a Radio Engineer and now lives in Finland with his family.

  • DEXA Workshops - Impact of Radio Irregularities on Topology Tradeoffs of WSNs
    17th International Conference on Database and Expert Systems Applications (DEXA'06), 2006
    Co-Authors: G. De Marcos, T. Yang, L. Barolli
    Abstract:

    The Radio model usually used in most of studies on wireless sensor networks is spherical. This means that the received power at a certain distance is the same in all directions. Every Radio Engineer knows that this is not the case encountered in real hardware. Here, we show that the analysis of such a network by simulation is not trivial when one uses more realistic Radio models. We emphasise this problem by comparing the impact of realistic simulations on the study of the infrastructure trade-offs of sensors networks. As expected, simulations confirm that more advanced simulation techniques are required in order to take into account wireless channel models and to bound the simulation time as well.
