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

Throughout its history, Understanding Telephone Electronics has been, by far, one of the most popular books on telecommunication electronics in the trade, electronic distribution, and educational markets because of its very simple, direct approach to the technology. In keeping with the distinguished tradition of its predecessors, Understanding Telephone Electronics, Fourth Edition covers conventional telephone fundamentals, including both analog and modern digital communication techniques, and provides basic information on the functions of each telephone system component, how electronic circuits generate dial tones, and how the latest digital transmission techniques work. This new edition of Stephen Bigelow's well-known, widely used text on telephone electronics offers comprehensive coverage of the latest developments in fiber optic technology, the convergence of telecommunications, cable-TV and Internet services, and CTI (computer telephony integration). The authors have made extensive revisions in these and other essential areas, such as business systems, voice mail, phone networking, enhanced services, satellite communications, wireless paging systems, digital communications, and much more to ensure that topics covered are current with the most recent advances in technology. The original Understanding Telephone Electronics has been a "gold standard" reference and training staple for years. Likewise, Understanding Telephone Electronics, Fourth Edition will serve as an essential and invaluable resource for technicians, engineers, students at major universities and corporations, and anyone with an enthusiasm for telecommunication electronics. Provides comprehensive coverage of telephone system functions and the role of the Internet in telephony Updates encompass the trends and advances of the booming telecommunications field, with new chapters on fiber optic technology and the Internet

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. The types of services that mobile telephone systems can offer vary depending on the technologies, devices and system types. Discover the key types of mobile services including circuit switched voice services, push to talk (dispatch) services, messaging, data services, location based services, multicast services. Learn how the new mobile telephone systems can offer services with different quality levels of service. Some of the most important topics featured are: . The Functional Parts of Mobile Systems . Basic Speech Coding, Access Methods and Modulation Types . Mobile Device Types . Basic Mobile Network Operation . AMPS, TACS, NMT, MCS, CNET and MATS-E 1G Systems . GSM, IS-136 TDMA and CDMA 2G Systems. . GPRS, EDGE, EVDO and EVDV 2.5G Systems . WCDMA/UMTS and CDMA2000 3G Systems . Basic 4G Requirements .
