WAP, SMS, i-mode, and Bluetooth are all compared and contrasted for their respective strengths and weaknesses, along with the existing and potential wireless markets. Other topics are mobile applications development languages and interoperability issues.
Suitable as both a professional trade reference and textbook for anyone interested in cellular technology, Cellular Networks: Design and Operation A Real World Perspective is the author s continuation of the invaluable Wireless Crash Course series originally published by McGraw-Hill, written by author and telecom expert Paul Bedell. Cellular Networks includes comprehensive information about the design and operation of cellular networks. The information included in this book is relevant to anyone: ? Teaching cellular technology classes or studying the industry Working at companies that manufacture end user devices like cell phones and tablets; such as Apple, Samsung, Blackberry, Kyocera, LG and others ? Working in the mobile application environment ? Employed by law firms that specialize in telecom and wireless ? Working for cellular carriers such as AT&T, Verizon, US Cellular, Sprint, T-Mobile, Cricket Wireless and others Working for equipment makers such as Alcatel Lucent, Ericsson, Fujitsu, Nokia Siemens, Commscope, Mobile Access, TE Written in an easily digestible style, Bedell s Cellular Networks avoids confusing and unnecessary technical details, conveying to readers well-researched, real-world data the average person will understand and will want to read! Instead of being bombarded with theoretical jargon, readers will get a clear picture of how cellular networks are designed, how they work, what equipment and components are vital to their operation, and how these components work together to create cellular network service. The book is a must-have primer for anyone and everyone who needs or wants a solid foundation in cellular technology.
FreeBSD is not particularly difficult to use, and its integrated documentation is adequate, but it can take a long time to figure out which packages you need to install in order to get certain services running, and how to configure them once installed. Even if you're familiar with the programs you need to use, learning how they work with FreeBSD can be a challenge. If you are totally new to Unix-like operating environments, this guide could be a little over your head in some places, but if you read it from start to finish and stick with it when things get difficult, you'll end up with a functional and useful operating system. If you already have some experience with any Unix-like operating system, you'll probably feel right at home with FreeBSD and may want to skip ahead to the sections that apply to you. While there are some suggestions and system administration tips sprinkled throughout The FreeBSD Crash Course, it is not designed to teach you how to administer a server. It's impossible to anticipate each reader's hardware configuration and goals for working with FreeBSD, so instead of telling you how to set up your machine to perform specific tasks, this guide will show you how to install and configure various services and programs. This Short Cut is organized into two sections: desktop and server. From those two starting points, you can customize FreeBSD to meet nearly any need. If you're new to FreeBSD, start at the beginning and skip ahead when you hit a section that isn't relevant to what you need to do.
This textbook takes a unified view of the fundamentals of wireless communication and explains cutting-edge concepts in a simple and intuitive way.

This easy-to-use primer will empower anyone—even those with no IT background—to face the challenge of adding one or more technologies to library services or maintaining existing technologies. Most of the public libraries in the United States are operating on tight budgets without allocation for IT personnel; in school libraries, the librarian often takes on the lion's share of IT responsibility. This book is an invaluable guide for library staff members who are put in the position of maintaining their own networks and computers with very little training or support. Authored by an assistant library director with years of firsthand experience working as a solo IT manager within public libraries, this guide provides practical information about overcoming the unique challenges of managing IT in a smaller organization, juggling multiple job roles, being limited by a restrictive budget, and working directly with the public. Crash Course in Technology Planning addresses a wide variety of IT topics in the library sphere, providing information in a logical manner and order. It begins with an explanation of triaging existing IT issues, then moves into diagnosing and repairing both individual PCs as well as the library Local Area Network (LAN). The following chapters cover other important topics, such as the best way to inventory computers and equipment, how to budget for and procure new equipment, and recommended ways for an IT layperson to set and achieve goals.
