This book explains the basic components, technologies used, and operation of IS-95 CDMA systems. You will discover why mobile telephone service providers have upgraded from 1st generation analog systems to more efficient and feature rich 2nd generation system. You will also discover how 2nd generation systems are gradually evolving into 3rd generation broadband multimedia systems. This book starts with the system components and basic services that the IS-95 CDMA system can provide. You will learn that the key types of CDMA devices include external radio modems, wireless PCMCIA cards, embedded radio modules, single mode and dual mode mobile telephones. You will then discover the different types of available services such as multiple types of voice services, data services, messaging services, and position location services. Explained are the physical and logical radio channel structures of the CDMA systems along with the basic frame and slot structures. Described are the fundamental capabilities and operation of the CDMA radio channel including channel coding, modulation types, variable speech coding, precise power control, and soft handoff. You will learn how each CDMA radio channel has 64 channel codes and that some are these are used for signaling (control channels) and others are used for user traffic (voice and data). Because the needs of voice and data communication are different, you will discover that the CDMA system essentially separates circuit switched (primarily voice) and packet switched (primarily data) services. Described are key functional sections of a CDMA network components and how they communicate with each other. You will learn how and why IS-95 CDMA is evolving into 3rd generation broadband systems including EVDO, EVDV, and CDMA2000.

<p>This book explains how and why people and companies are using IP television and Internet television services. You will discover how global television services are already available through the Internet and how you can use standard television to watch global television channels using analog television adapter boxes. The fundamentals of how IP Television works is provided. You will discover how IP television can be watched on different types of viewing devices such as standard televisions with adapters, dedicated IP televisions, multimedia computers and mobile telephones. IP television service allows viewers to have more control of Internet television services. This control ranges from instant service activation to real time television on demand controls. Some of the advanced Internet television features such as personal media channels, anywhere television extensions, global television channels and multimedia programs are described. In addition to the traditional ways of television channel selection, you will learn about new ways television channels can be search and selected using interactive electronic programming guides (EPGs). The different types of media formats that are used for IP television services are explained along with their control protocols. Not all IP Television systems and services are the same. There are cost and quality tradeoffs along with common problem areas and risks. You will discover how the audio and video service quality can range from poor to above the quality that is already delivered to standard TV. Because each IP television viewer has a unique address, this allows advertising messages to be sent to specific viewers (addressable advertising). The ability to direct advertising messages to specific target audiences (addressable advertising) is more valuable to companies than traditional broadcast advertising and this may result in reduced viewing costs.</p>
