Abstract

Internet heeft ons leven veranderd, de dag van vandaag gebeurt er zoveel online dat mensen te alle tijde verwachten om toegang tot het internet te hebben. Het aanbieden van internettoegang aan boord van de trein past dan ook perfect binnen de verwachtingen van de passagiers. Echter, het aanbieden van continu, breedband internet aan boord van een trein is een dure zaak terwijl passagiers dit zien als een dienst die hen weinig of niets mag kosten. Door hetzelfde netwerk te gebruiken voor andere diensten kunnen de betrokken actoren extra opbrengsten genereren of kunnen lagere gebruikskosten voor de passagiers bereikt worden. Om dit probleem concreet aan te pakken werd een GIS-gebaseerde tool ontwikkeld die toelaat om een complexe relationele database op te bouwen door data van verschillende databronnen aan elkaar te koppelen. Deze database bevat enerzijds data van treinlijnen, treinen, spoorwegen en stations en anderzijds de locaties en technische eigenschappen van alle relevante gsm-masten. Op basis van deze database en een aantal invoerparameters kan de tool de beschikbare bandbreedte per technologie en de benodigde bandbreedte per dienst in kaart brengen om zo regio's met een tekort aan bandbreedte te bepalen. Achteraf worden er locaties voor nieuwe antennes berekend waardoor ook deze probleemregio's een optimale netwerkdekking bekomen. Tot slot wordt een optimaal aanbod van diensten berekend. Dit is een aanbod van een aantal diensten waarbij elk van de aanwezige actoren een positieve business case bereikt. Het eindresultaat is een grafische weergave van de waardestromen per actor, de totale kostprijs voor het aanbieden van de diensten en de locaties van de nieuwe antennes. The internet has literally changed our lives, we have become so used to the fact that we can be online all the time. Because of this, it seems like a good idea to offer internet access to train passengers. However, creating a continuous broadband internet connection aboard a train is an expensive matter, while passengers prefer to pay as little as possible. By opening this internet connection to other companies, a whole variety of services can be implemented by a number of external actors. Because of these extra services, costs for the passengers can decrease while extra revenues are generated for all involved actors. To tackle this complex problem a GIS-based tool has been developed. This tool allows to build a complex relational database based on a number of data sources. This database contains all train related data like the location of the tracks and stations and the list of stations for each train line. Furthermore, it contains all the technical parameters for all involved cellular towers.Using this database and a number of parameters, both available bandwidth per technology and per operator and required bandwidth per service can be calculated. Based on this, regions which lack bandwidth can be mapped and for each of these regions the optimal location of new antennas is calculated.Finally an optimal set of services is calculated. In this set of services, all involved actors have a positive business case. The final output of the GIS-based tool is a graphical representation, showing the value network between actors, the total cost for implementing the set of services and the location of new antennas.

Abstract

Annotation "As research for future fourth generation (4G) mobile communication systems is underway worldwide in major companies and academic institutions, forward-thinking professionals are striving to gain a thorough understanding of the cutting-edge technologies and design techniques that will make these systems work. This book helps readers do just that by: providing a comprehensive introduction to multicarrier techniques for 4G mobile communications with a special focus on the analytical aspects; explaining radio channel characteristics and phenomena and discussing the advantages and disadvantages of the OFDM scheme; featuring new multicarrier-related techniques, MC-CDMA, research on several 4G systems, and a look at several problems to be overcome with these systems; examining the concept and detail of the ODFM scheme and how to carry out theoretical analysis on the performance of transmission systems in radio channels; showing how ODFM has been successfully adopted as a modulation scheme in communications systems and broadcasting systems such as ADSL, wireless LANs, and DVB-T."--BOOK JACKET.

Abstract

Destiné aux étudiants de cycle Master, aux ingénieurs et aux enseignants-chercheurs, ce livre décrit les protocoles et le fonctionnement des réseaux cellulaires depuis la troisième génération jusqu'aux évolutions les plus récentes. L'ouvrage commence par une revue des notions fondamentales nécessaires à la compréhension du sujet et donne une vision d'ensemble des versions (releases) du 3GPP pour les communications radiomobiles. Il décrit ensuite les interfaces radio UMTS, HSDPA, HSUPA, HSPA+ et LTE en insistant sur leurs différences et leurs points communs, les avancées et les inconvénients de

Abstract

Im November 2000 fand in Österreich die Versteigerung von Frequenzen für die dritte Mobilfunkgeneration (UMTS) statt. Zuvor waren bei den UMTS-Auktionen in Großbritannien und Deutschland die höchsten jemals bei einer Auktion erreichten Erlöse erzielt worden. Nicht zuletzt deshalb rückte die Vergabe von Frequenzen in das öffentliche Interesse. Die Publikation beschäftigt sich mit einer der Kernfragen der Regulierung in der Telekommunikation: der Vergabe der knappen Ressource Funkfrequenzen. Der Autor untersucht die Voraussetzungen für eine effiziente Nutzung des Frequenzspektrums sowie unterschiedliche Vergabeverfahren unter ökonomischen Gesichtspunkten, wobei er besonderes Augenmerk auf Frequenzauktionen legt.

Abstract

This newly revised edition of an Artech House bestseller provides you with an up-to-date introduction to third generation (3G) mobile communication system principles, concepts, and applications. The book clearly presents the basics of UMTS systems in one comprehensive volume, without bogging you down with advanced mathematics. The second edition includes an even more thorough treatment of potential 3G applications and descriptions of new, emerging technologies such as 3G System Release number 5, HSDPA, and Multimedia Broadcast/Multicast Service (MBMS). It also features discussions on both 3GPP and 3GPP2 evolution paths, the specification process, and future 3G upgrades. You get a complete overview of UMTS systems, information on the latest 3G technology standards, a review of the wideband CDMA air interface, network architecture details, and guidance in network planning and management. Other key topics include new concepts in the UMTS network, 3G system signaling procedures, 3G services and applications, modulation and coding, and standardization organizations and industry groups. An exhaustive list of references, including key website addresses, is provided in every chapter to help you gain access to further information.
