About this product: This book explains how the 1x Evolution (1XEV) data only (EVDO) system modifies (optimizes) the 1.25 MHz IS-95 radio channel structure to provide high-speed data services (up to 2.4 Mbps) to wireless customers. The EVDO system allows cellular service providers carriers to use one of more IS-95 CDMA radio channels (with changes) to provide broadband high-speed data services to their customers. The EVDO is an "always-on" system that allows users to browse the Internet without complicated dialup connections.
You will learn that the key types of EVDO devices include external radio modems, wireless PCMCIA cards, embedded radio modules, and mobile telephones. External radio modems allow the customer to simply plug in their EVDO device to their USB or Ethernet data port to their desktop or laptop computer. EVDO PCMCIA cards can be added to most laptop computers or embedded radio modules allow devices such as PDAs and Laptops to integrate high-speed wireless without adding PCMCIA cards. Some CDMA mobile telephones include both IS-95 CDMA (voice and low speed data) and EVDO (high-speed packet data) capability.
Because the needs of voice and data communication are different, the airlink design of the IS-95 and EVDO radio channel structures are different. 1xEV devices can have single mode (only EVDO) or dual mode (both IS-95 voice and EVDO data) capability. You will discover how single mode devices can only access the high-speed data rate (HDR) services on the EVDO radio channel and dual mode devices can access either the EVDO HDR channel or the IS-95 voice and medium-rate data traffic channels.
This book provides the basic technical components and operation of EVDO technology. You will learn the physical radio channel structures of the 1xEV system along with the basic frame and slot structures. Described are the logical channels and their functions. Explained are the key EVDO network components and how they communicate with each other.
Explained is the fundamental capabilities and operation of the EVDO radio channel including asymmetric data rates, adaptive modulation (QPSK, 8-PSK, or 16-QAM), and the use of a single control channel with multiple capabilities. You will discover how a scheduling algorithm can be used to fairly allocate the necessary data rates for EVDO users is provided. Described are the 64 coded channels and how up to 60 of them are available to provide data services to active users and how many other users (possibly 600 per channel) can be added who have a 10% usage activity factor.
To make the EVDO data channels transparent with the IS-95 CDMA voice channels, handoffs can occur between IS-95 CDMA radio channels and EVDO radio channels. Some of the most important topics featured in this book are:
· How EVDO provides wireless Broadband data services · The fundamental components and operation of EVDO systems · Differences between EVDO data and IS-95 traffic/voice channels · The types of EVDO products and their uses · How EVDO services are setup using manual or over the air programming · The EVDO radio channel structure · The different types of physical and logical channels · EVDO network components · Network connections · How EVDO technology continues to evolve
About this product: EV-DO: Rev-0 and Rev-A is a unique book designed for CDMA professionals in the Wireless Communications Industry worldwide. It is intended to serve as a reference book for EV-DO Physical Layer. Performance Evaluation and optimization engineers, Network Operation personnel and Cell Techs will greatly benefit from this publication. To enhance comprehension, dozens of original analogies are used throughout the book to convey important concepts in an intuitive and enjoyable manner. Chapter 1 sets the stage for the book with the Evolution of Wireless communications. Chapter 2 summarizes the organization of the 1xEV-DO standard. Chapter 3 compares Rev-0 to Rev-A; outlines their common traits and underscores their differences. Chapters 4, 5 and 6 present a detailed operation of the Forward and Reverse Links. Chapter 7 discusses key operational considerations in EV-DO networks. We close the book with a unique, rich and very informative series of CDMA mini-tutorials in the Glossary section.
About this product: The cdma2000 packet data network is one of the major enhancements made to IS-95 based CDMA networks. cdma2000 packet data networks are designed to provide efficient wireless Internet services. It is based on IETF standards such as Mobile IP, RADIUS, L2TP, etc. Service providers have begun to equip their networks with cdma2000 packet data networking capability. This course offers a detailed understanding of cdma2000 network components, protocols and services. It is a must for both operators and equipment manufacturers to understand issues in design and deployment of cdma2000 packet data services. This course focuses mainly on Simple IP service since it will be the first service to be deployed. Another important aspect discussed in this course is the accounting. Packet data accounting is one of the least understood subjects in the wireless Internet world. This course explains how accounting for packet data services work in cdma2000 networks. By way of example, there is a discussion of some useful services such as Virtual Private Networks and Instant Messaging

About this product: ZTE's support for EV-DO rev. B is well known. Its support for multi-standard base stations and LTE is equally well known. Rolling out rev. B alongside LTE, then, isn't surprising. Nor is it a differentiator against other CDMA2000 vendors.
About this product: This book explains the basics of circuit switched and packet data via a variety of wireless mobile systems. Included are descriptions of various public and private systems that are used for mobile data and messaging services. You will learn the different types of systems that can be used for mobile data ranging from simple cellular data connections to mobile telephones to dedicated packet radio communication systems and how the cost of these systems can range from less than a few pennies per gigabyte to over $10 per kilobyte. In addition to traditional mobile data systems, wireless system operators are converting their voice, dispatch, and paging systems to two-way mobile data systems. This has resulted in a much lower cost of sending mobile data, and it has increased consumer awareness of the availability and reliability of mobile data services. Because the needs of voice and data communication are different, the operation of the mobile data radio is different. The reliability, cost, and bandwidth limitations compared to wired communication systems can significantly vary. This book provides an understanding of what some of the key differences between mobile data systems and services. You will discover that the key types of mobile data devices include external radio modems, wireless PCMCIA cards, embedded radio modules, and mobile telephones. External radio modems allow the customer to simply plug in their mobile data device to their USB or Ethernet data port to their desktop or laptop computer. Wireless data PCMCIA cards can be added to most laptop computers or embedded radio modules allow devices such as PDAs and Laptops to integrate high-speed wireless data. Some mobile telephones include both voice and mobile data capability. Mobile data devices can have single mode (data only) or they may provide for dual mode (voice and data) capability. You will discover how the mobile data system can have dramatically different data transmission rates. In introduction to the different types of mobile data systems is covered including cellular data, DataTac™, Mobitex, CDPD, GPRS, EVDO, HSDPA and WLAN hot spots is provided. You will learn the basic operation and components, how these systems operate and the basic services that they can provide.
