Editorial Review:

Cover story, From 'Virtualization' to 'Realization' — IT's New Focus on Infrastructure and Operations is just one of the features of this edition of Research Digest : The pendulum continually swings, first to the virtual, then back to the real. After flirting with progressively less concrete objectives, the attention of management has begun to turn back toward recognizing the criticality of basic operational excellence. Failure is becoming too expensive, dependency chains are lengthening and the interoperation of multiple technologies is becoming the default mode of operation. The strength or fragility of systems has once again become a dominant concern. Businesses are experiencing a renewed emphasis on infrastructure and operations. Giga analysts are seeing increased interest in the optimization of such seemingly mundane assets as networks, servers and storage, and a strong focus on metrics that allow the measurement of value received from the infrastructure and its health. At the same time, there is renewed focus on how well development staffs are updating their skills and processes. With this report, learn about: Software - Making Metrics Matter. In software development, the abstraction has always sought to become the application. Portals provide process personalization. Virtualization shows up in cultural provinces as well. Making Operations Count - Literally. At the end of the day, nothing is more real than operations.

Editorial Review:

Companies with far-flung international operations should consider outsourcing non-critical international connectivity and telecom networking services, to focus internal IT on strategic activities to build revenues from core business activities. By 2003, the majority of Global 2000 companies will selectively outsource some or all of their international wide area data networks (WANs) and more than 40 percent of enterprises with operations spanning three or more continents will adopt managed converged WAN services, offered by a major global network operator. During the next three years, emerging international telecommunications players will join established players in expanding international IP-based networks and introducing business networking services into the largest international markets. They also will broaden their portfolios to include end-to-end services — managed international frame relay, Internet virtual private networks (VPNs), global Internet and remote access roaming and Web hosting. Successful international service providers will offer Global 2000 multinational customers what they want most, including: Improved service levels for end-to-end data and multimedia WAN services Bundling and integrated telecom services that include multiservice price discounts Superior customer responsiveness and service-level agreement (SLA) compliance

Editorial Review:

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.
