Product Description
The goal of Unlicensed Mobile Access (UMA) is to provide seamlessaccess to GSM and GPRS mobile service networks via unlicensed spectrumtechnologies, including Bluetooth, WiMAX, and Wi-Fi. Expanding on thelevel of knowledge in this growing field, Unlicensed Mobile Access Technology: Protocols, Architectures, Security, Standards, and Applicationspresents the first complete cross-referenced resource exploring UMA andUMA-relevant technologies.When operating successfully, the technologysupporting dual-mode enabled mobile terminals allows subscribers toroam freely and seamlessly between cellular networks. However, varioustechnical challenges still occasionally impede clear communication.This book explores the complex issue of mobility management andemphasizes the need for intelligently designed vertical and horizontalhandoff algorithms that will improve adaptability in heterogeneouswireless environments. In addition, it reviews the various strategiesto guarantee Quality-of- Service (QoS) during movement and handoff.The first chapters introduce the basic technology of these systemsand discuss QoS, resource management, mobility management, and securityissues in UMA technology. The middle section concentrates on protocolsand security challenges in UMA-related technologies, which includeBluetooth, WirelessPAN, Wi-Fi (IEEE 802.11) and WiMAX (IEEE 802.16).The final chapters present standard specifications and variousapplications.
Comprised of contributions from world-wide experts, this book is acomplete reference, offering guidance on all aspects of the technicaland practical issues in UMA technology.
