Managing Service Level Quality Across Wireless And Fixed Networks

QoS (Quality of Service) and Network Management are old topics. However, the fusion of IP style multimedia and wireless networks (3G) means that network managers who might previously have dealt with one or the other, must now manage and provide service guarantees for the both. This is where Managing Service Level Quality across Wireless and Fixed Networks steps in…
It begins by examining the mechanisms that already existed in fixed IP data networks prior to the introduction of probe and agent technology. A look at these later developments is then supplemented with a real-world scenario of how real time application performance monitoring can not only provide service level management but can also aid in root cause analysis.
This same model is then applied to a wireless environment examining which elements are required to be able to deliver multimedia services across 2nd and 3rd generation mobile networks, detailing the components of data networking that will assist in guaranteeing service level performance and the constraints placed on those guarantees when passing services over an air interface to a wireless-enabled device.

As the demand for broadband services continues to grow worldwide, traditional solutions, such as digital cable and fiber optics, are often difficult and expensive to implement, especially in rural and remote areas. The emerging WiMAX system satisfies the growing need for high data-rate applications such as voiceover IP, video conferencing, interactive gaming, and multimedia streaming. WiMAX deployments not only serve residential and enterprise users but can also be deployed as a backhaul for Wi-Fi hotspots or 3G cellular towers. By providing affordable wireless broadband access, the technology of WiMAX will revolutionize broadband communications in the developed world and bridge the digital divide in developing countries. Part of the WiMAX Handbook, this volume focuses on the standards and security issues of WiMAX. The book examines standardized versus proprietary solutions for wireless broadband access, reviews the core medium access control protocol of WiMAX systems, and presents carriers' perspectives on wireless services. It also discusses the main mobility functions of the IEEE 802.16e standard, describes how to speed up WiMAX handover procedures, presents the 802.16 mesh protocol, and surveys the testing and certification processes used for WiMAX products. In addition, the book reviews the security features of both IEEE 802.16 and WiMAX. With the revolutionary technology of WiMAX, the lives of many will undoubtedly improve, thereby leading to greater economic empowerment.




Tremendous technological advances have been made in the development of low-cost sensor devices equipped with wireless network interfaces.
This book explains the functional parts of a Wireless LAN system and their basic operation. You will learn how WLANs can use access points to connect to each other or how they can directly connect between two computers. Explained is the basic operation of WLAN systems and how the performance may vary based on a variety of controllable and uncontrollable events. This book will explain the key differences between the WLAN system versions such as frequency and data rates along with which versions are compatible with each other. Tips are included on how to install a WLAN system along with common problems you may encounter and solutions you may use. Included is an overview of Ethernet technology and how it applies to 802.11 Wireless LAN. The fundamentals of frequency hopping and spread spectrum technology that are used in 802.11 systems will help you to understand how 802.11 systems can co-exist with devices that use the same ISM frequency band. Covered are the differences between 802.11, 802.11a, 802.11b, and 802.11g. You will learn how 802.11 systems can use independent DCF "Ad-hoc" and/or controlled PCF "non-contention" based operation. The different types of antennas that are commonly used in WLAN systems are explained and you will discover the typical range for WLAN systems and how to extend the range of WLAN systems through the use of directional antennas. Discussed are the basic steps for equipment configuration and options you may want to consider to maintain system security. Brief overviews of 802.16 UWB and the use of proprietary protocols to enhance the capabilities of 802.11 are included.
