This book explains the different types of mobile telephone technologies and systems from 1st generation analog to 3rd generation digital broadband. It describes the basics of how they operate, the different types of wireless voice, data and information services, key commercial systems, and typical revenues/costs of these services. While new competition has provided lower cost services for consumers, it means a rapidly changing marketplace for the wireless industry. Some of these changes include the increase in mobile telephone customers from 300 million to 1.3 billion customers within 5 years and the shift of focus from adding new voice customers to providing advanced services such as data transfer, web browsing, and software downloads. The types of services that mobile telephone systems can offer vary depending on the technologies, devices, and the services selected by customers. This book discusses the different types of systems including 1st, 2nd, 2.5, and third generation wireless (3G). Some of the most important topics featured are: - Simple descriptions and diagrams of analog and digital mobile telephone systems- The key types of wireless services and which types of mobile telephone systems can offer them- The approximate usage fees for mobile telephone services- The market numbers and trends for mobile subscribers- How each mobile telephone system continues to change to offer new services and better compete against other mobile telephone technologies.- What are the key applications driving the mobile telephone market growth.- What are the next steps in mobile telephone systems such as 4G

This book explains why people and companies are converting some or all of their existing (legacy) telephone systems from dedicated telephone systems (such as proprietary PBX) to more standard IP telephony systems. These conversions allow for telephone bill cost reduction, increased ability to control telephone services, and the addition of new telephone information services. Through the use of IP telephony service, companies can immediately reduce their telecommunication costs 40% to 70%. This book provides an overview of the different types of IP Telephony systems including IP PBX, IP Centrex and Internet Telephone systems. You will learn the key functional parts of voice over IP systems and how voice over Internet protocol (VoIP) systems work. Explained are the processes used to setup and control IP telephony service. The common IP Telephony protocols including session initiation protocol (SIP), Media Gateway Control Protocol (MGCP) and H.323 are described as well. You will learn how to connect telephones through data networks using adapters or by using telephones that plug directly into data networks (IP telephones). Discover what equipment and service choices you have and how they can affect your costs and service quality. Find out how packet losses and packet delays creates distortion and operational challenges and ways to reduce or eliminate these effects. Advanced telephone features that are only possible through IP Telephony are described along with how customers can setup and configure their equipment through the use of self provisioning web portals. Learn about the different types of services, their typical costs and some of the hidden costs of IP Telephony and ways to reduce or avoid them. Some of the most important topics featured are: .The different types of IP Telephony systems .Functional parts of VoIP systems .The processes used to setup and control IP telephony service .How to connect standard telephones through data networks .What choices you have and how they can effect your service quality .Advanced telephone features that are only possible through IP Telephony .The different types of services and their typical costs .Some of the hidden costs of IP Telephony

This book explains the different types of mobile telephone systems and how they are the evolving from 1st generation analog, through 2nd generation digital to high-speed 3rd generation digital broadband systems. It describes the key components, how they operate and the different types of wireless voice, data and information services they can provide. You will learn the terminology (terms and acronyms) for mobile telephone systems along with the key technologies. Learn how speech compression (voice coding) operates and how it allows more than 10 times as many users to share a single communication channel. Discover the different types of system access technologies including FDMA, TDMA, CDMA and SDMA. Explained are the basic types of modulation technologies and how they are evolving to increase the data transmission rates with less available bandwidth. Find out why and how cellular systems are converting from dedicated circuit switched connections to high-speed packet data systems. The key parts of mobile communication systems are described including mobile equipment, radio access network (RAN) and the core network (CN). You will learn the basic operation of the base stations and how they may communicate with mobile switching systems (MSC) for voice communication or how they communicate with packet switching systems for data communication (such as accessing the Internet). You will learn about the different types of mobile devices including multi-mode handsets, embedded communication devices, data-only cards and adapter boxes. Learn the key types of 1st generate analog cellular systems including AMPS, TACS, NMT, MCS, CNET and MATS-E. Discover how 2nd generation digital cellular increased the system efficiency to allow between 3 to 20 times the number of customers to share each radio channel. You will learn the basics about GSM, IS-136 TDMA and CDMA systems. Explained is the evolution of 2nd generation mobile systems into 2.5G systems that can offer medium speed data services (approximately 500 kbps). The systems covered include GPRS, EDGE, EVDO and EVDV. The wideband 3rd generation systems WCDMA/UMTS and CDMA2000 are described along with how these systems can allow 50 to 100 users to simultaneously share each radio channel and how they can offer many new types of services.
