Finally--a single volume guide to really effective security for both voice and data wireless networks!More and more data and voice communications are going via wireless at some point between the sender and intended recipient. As a result, truly ""bulletproof"" wireless security is now more than a desirable feature--instead, it's a necessity to protect essential personal and business data from hackers and eavesdroppers.In this handy reference, Praphul Chandra gives you the conceptual and practical tools every RF, wireless, and network engineer needs for high-security wireless ap

De markt van mobiele communicatie is nog altijd het snelst groeiende segment van de wereldwijde computer- en communicatiemarkt. Jochen Schiller behandelt in zijn boek Mobiele communicatie uitgebreid de huidige stand van zaken in de technologie en het onderzoek van mobiele communicatie, en schetst daarnaast een gedetailleerde achtergrond van het vakgebied. In het boek worden alle belangrijke aspecten van mobiele en draadloze communicatie besproken, van signalen en toegangsprotocollen tot beveiliging en de eisen die applicaties stellen. De nadruk ligt hierbij op de overdracht van digitale data. Schiller illustreert de theorie met vele voorbeelden en maakt gebruik van diverse didactische hulpmiddelen, waardoor het boek zeer geschikt is voor zelfstudie en gebruik in het hoger onderwijs.

In cellular networks, a new generation of CDMA or WCDMA-based networks will start operations in most countries in the near future. The standardized WCDMA technology generates new challenges in radio network planning, optimization and QoS management because of the dynamic nature of its radio interface and various new services and different network operating modes. Moreover, new and modified radio planning phases as well as new field measurements and emphasized QoS management are needed when UMTS networks are designed and optimized. Hence, a practical UMTS planning process must be defined in detail, from dimensioning to optimization tasks. This book follows the UMTS planning process. It is organized in three parts: Part I - UMTS configuration planning; Part II - UMTS topology planning; and Part III - UMTS network functionality. The first chapter in Part I introduces the UMTS and UTRAN systems and radio network planning strategy, and defines a planning process for UMTS. In Chapter 2, the UMTS planning process is covered, and a detailed description of the UMTS power budget is given, with planning threshold examples provided.

Design and Performance of 3G Wireless Networks and Wireless LANs is for wireless communication system engineers, network engineers, professionals, and researchers. Network architectures of UMTS, CDMA2000 systems, and how major network elements within the 3G networks can be designed, are described. In addition, the authors describe how end-to-end performance for voice and data services can be determined. They also provide guidelines on how radio access networks and core networks can be engineered. Of equal importance, is inclusion of explanations of various wireless LAN standards (IEEE 802.11a, 802.11b, 802.11g, 802.11e) and how voice and data services can be offered in the wireless LAN systems. Additional highlights include: * Overview of core principles of wireless communications (e.g., FDMA, TDMA, CDMA), airlink capacity analysis, and evaluation. * Traffic model descriptions and illustrations for circuit-switched and packet-switched services. * In-depth coverage of how base station and radio network controller can be designed to meet capacity requirements. * Discussion of unique design issues in 3G networks, innovative solutions, and possible new 3G features. This material also provides capacity engineering guidelines for 3G networks and wireless LANs. Review exercises are provided at the end of each chapter to facilitate teaching and self study.
