With around 3 billion subscribers, GSM is the world's most commonly used technology for wireless communication. Providing an overview of the innovations that have fuelled this phenomena, GSM: Architecture, Protocols and Services, Third Edition offers a clear introduction to the field of cellular systems. Special emphasis is placed on system architecture and protocol aspects, and topics range from addressing concepts through mobility management to network management. This third edition contains around 25% new and reworked material and has been thoroughly updated to encompass recent advances and future trends. It serves as both an introductory textbook for graduate students as well as a reference resource for telecommunications engineers and researchers. This edition: . Presents capacity enhancement methods like sectorization, the application of adaptive antennas for Spatial Filtering for Interference Reduction (SFIR) and Space Division Multiple Access (SDMA). Provides a detailed introduction to GPRS, HSCSD, and EDGE for packet-switched services and higher data rates. Features updated coverage on the vastly expanded range of GSM services, including an examination of Multimedia Messaging Service (MMS). Adopts a highly graphical approach with numerous illustrations. |

Sommario/riassunto |
|
This publication aims to contribute to the research, analysis and design of proposals for the social protection of older persons. It develops a new conceptual approach and uses various indicators for its assessment in the areas of social security, health and social services. All human beings must be able to avail themselves of equal rights, without discrimination, and these rights must be enforced through serious, strategic and sustainable commitments which accommodate both present and long-term challenges. Only then will it be possible to develop an approach which includes each and every citizen and contributes to their well-being and security, so that they can make full use of their capacities, regardless of their age or economic activity. |
