Editorial Review:

Asynchronous Transfer Mode (ATM) is a high-speed packet switching network technology industry standard. ATM networks have been deployed because they offer the ability to transport voice, data, and video signals over a single system. The flexibility that ATM offers incorporates both circuit and packet switching techniques into one technology, creating a variable transport network solution with simple network processing functions. ATM Basics provides an understanding of how the systems operate and the applications that use ATM systems. ATM has become the world standard that is used to interconnect telephone and data networks. This book covers the operation of ATM systems and it explains how ATM packet switching is much faster than other types of packet switching technologies. You will learn that ATM standards include ATM adaptation layers (AAL) that define how to connect ATM systems to other types of communications networks such as voice and IP networks. Explained are the processes that are used to monitor and control different levels of quality of service (QoS). You will discover that ATM packets can be sent over a many types of physical links including wireless, optical, coax, and copper lines. ATM provides for different services including CBR, VBR, and ABR. ATM services provide key applications including PVCs, SVCs, VDT, LANE, and IP. If you are involved in telephone networks, computer networks, cable television networks, wireless networks or other telecommunications systems and equipment, ATM is almost certainly part of your system and you need to understand how it works and what it can do. Some of the most important topics featured are: ( Understand why ATM has become the world standard used to interconnect telephone and data networks ( The operation of Asynchronous Transfer Mode (ATM) systems ( Ways ATM interconnects to other technologies such as Frame Relay ( Ways that ATM packets are transmitted over physical links ( The Quality of Service (QoS) features used in ATM systems. ( Why ATM can be used efficiently for voice, data and video services. ( How signaling and switching is performed in ATM networks. ( ATM services such CBR, VBR, and ABR ( Learn about key applications such as PVCs, SVCs, IMA, LANE and IP over ATM. ( ATM terminology and industry standards

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.

Editorial Review:

This book explains the different types of paging systems and how they are changing. Traditional paging services have seen a world decline of over 65% in the number of human between 1988 to 2004. During this decline, some paging systems have experienced high-growth in new areas such as short messaging and telemetry. Paging systems provide reliable information transfer that reaches many places that are not reachable by other types of mobile or satellite systems. Explained is how and why paging systems are transitioning from one-way systems to two-way systems. Covered in this book are the key paging industry standards including as POCSAG, ERMES, FLEX, and REFLEX to standardize equipment and services. This has resulted in a dramatic reduction in equipment and usage costs for the customer and the availability of amazing new devices. The paging industry continues to evolve with innovative technologies and services that provide for new communication applications. This book covers some of the near-term changes that will affect the paging industry. Some of the most important topics featured are: - Simple descriptions of paging system types - The market numbers and trends for the paging industry - The key types of paging services - Why two-way paging is more efficient for the operator and customer - Paging industry standards including POCSAG, ERMES, FLEX, and REFLEX - The approximate usage fees for paging services - Amazing new types of paging devices - How the paging industry is changing to compete with other wireless systems - What are the key applications driving the paging market growth. - The future of paging systems
