Broadband Fixed Wireless

With the advent of the IEEE 802.16 standard, Broadband Fixed Wireless Access (BFWA) is becoming a new hype for high-speed internet access for residential customers and small and medium enterprises (SMEs). Up till now, a large variety of incompatible wireless solutions were promoted for BFWA. Moreover, these solutions only worked under restricted operating conditions and hence had a high operational cost for installation and maintenance. Both shortcomings are eliminated by the new standard.

Recognizing the importance of this standard, we started in 2001 a spin-off company of IMEC, LoraNet, with funding of the IMEC Incubation Fund. LoraNet had the mission to become a leading provider of BFWA technologies. LoraNet could capitalize on the IMEC know-how on Wireless Local Area Network (WLAN) systems and actively developed techniques to reduce the total cost of ownership of a BFWA solution for the operators.

To this end, we participated in the development of the IEEE 802.16 standard and its European counterpart, HIPERMAN. LoraNet also executed an SME development project that was fiinded by the Institute for the Promotion of Innovation by Science and Technology in Flanders (IWT). In addition, LoraNet participated in the European IST-STRIKE project, which investigates multi-antenna techniques for BFWA as well as the bridging between BFWA and WLAN.

Due to the lack of venture capital LoraNet had to be closed down in mid 2003. Nevertheless, the interest in BFWA is still growing and we did not want that the experience that was build up in LoraNet, got lost. Therefore we bundled our experience in a tutorial for the 2004 International Conference on Communications (ICC) in Paris. The success of this tutorial led us to the idea to reach a wider audience by extending the tutorial material into a manuscript. The result of this effort is in front of you. We hope that you enjoy reading it and that it is useful in your professional work.

MS Windows Server R2

Windows Server 2008 R2, or simply R2 for short, is the second release of Windows Server 2008. It isn’t a completely new release, but rather adds additional features and refinements to the existing release. In this book, we focus on the new features and refinements in R2. We assume you have at least a general knowledge of Windows Server, and that you have some familiarity with Windows Server 2008, although we don’t assume you’re actively running Windows Server 2008. Where an R2 feature is a refinement of a feature that was new in Windows Server 2008, we provide background on the Windows Server 2008 feature to provide context.

Windows Speed Secrets

XP Speed Secret #1: Disable Extra Startup
Programs

There are certain programs that Windows will start every time you boot up your system, and during the startup phase, they're all competing for a slice of your CPU speed. Extra or unwanted items in the startup list will definitely increase your startup time, perhaps by several minutes. Some common examples are things related to AOL, RealPlayer, Napster, instant messengers, and video managers. If you're not sure about an item, no big deal. You can turn it off, restart your PC, and see if everything seems to work. If not, you can always go back and re-enable an item in the Startup list. This tip alone should speed up your start-up by 250%. Here are is what
you have to do:
1. Go to Start button  Run
2. Type "msconfig", without quotations
3. Hit enter key or click the OK button
4. A System Configuration Utility window will show up
5. Click the Startup tab
6. In the Startup tab you will see several boxes and some of them will selected (checked). All you have to do is to uncheck extra items that are of no use. If you run an antivirus program it is not recommended to uncheck it.
7. After making you choices press the OK button, you will be prompted to restart computer to apply changes.
8. After restarting your computer a dialogue will be displayed. You can check the option for not showing this dialogue every time your PC reboots.

Autocade 2007

Welcome to the AutoCAD 2007 and AutoCAD LT 2007 Bible. Whether you use AutoCAD or AutoCAD LT, you’ll find complete explanations of all of the powerful features that you need to know to design and draw anything. This book is designed to be your comprehensive guide to both the AutoCAD and AutoCAD LT programs. This book covers every significant AutoCAD and AutoCAD LT feature. If you’re a beginning user, you’ll find everything you need to start out; if you’re already using AutoCAD or AutoCAD LT regularly, the book covers advanced material as well. Although you can use this book as a tutorial if you’re just starting out or learning a new set of features, it also provides a solid reference base to come back to again and again.

The short tutorials on almost every topic will quickly have you drawing professionally. The CD-ROM is chock-full of drawings, a trial version of AutoCAD 2007, and add-in programs (which are mostly for AutoCAD only). This book should be all that you need to make full use of either program. For AutoCAD 2007, the emphasis is on 3D tools, including new 3D objects, new ways of navigating in 3D, and a completely new environment. For AutoCAD LT 2007, the emphasis of the new features is on ease of use and automation, including dynamic blocks and object snap tracking.

For both programs, layer tools that were previously in the Express Tools set have been incorporated into the core program; these are available for AutoCAD LT for the first time. Other minor changes make drawing easier and faster.


Part I: AutoCAD and AutoCAD LT Basics

Part I provides the background information that you need to start drawing. It starts with a “quick start” that has you drawing right away, and then covers how to start a drawing, use commands, specify coordinates, and set up a drawing.

Part II: Drawing in Two Dimensions

Part II covers all of the commands and procedures for drawing and editing in two dimensions. In addition, I discuss how to control the drawing process with layers, zooming, and panning. Also included in this part is information about dimensioning, plotting, and printing.

Part III: Working with Data

Part III covers many ways to organize and share data, including blocks, attributes, external references, and external databases.

Part IV: Drawing in Three Dimensions

Part IV explains everything that you need to know to draw in three dimensions. It also discusses how to present 3D drawings using hiding, shading, and rendering techniques.

Part V: Organizing and Managing Drawings

Part V helps you to incorporate AutoCAD and AutoCAD LT into your work world by explaining how to set standards, manage drawings, and work with other applications. It concludes with a chapter on getting drawings on the Internet.

Part VII: Programming AutoCAD

Part VII introduces you to programming AutoCAD. It includes three chapters on AutoLISP and Visual LISP, and one chapter on Visual Basic for Applications. This part applies to AutoCAD only.

Part VIII: Appendixes

Part VIII provides additional information for AutoCAD and AutoCAD LT users. Appendix A gives instructions for installing and configuring AutoCAD and AutoCAD LT. Appendix B covers further resources for AutoCAD and AutoCAD LT users. Appendix C explains what you’ll find on the CD-ROM.

USB Complete Third Edition

This book is for developers who design and program devices that use the Universal Serial Bus (USB) interface. My goal is to introduce you to USB and to help you get your devices up and communicating as quickly and easily as possible.

The USB interface is versatile enough for a wide range of peripheral devices. Standard peripherals that use USB include mice, keyboards, drives, printers, and audio/video devices. USB is also suitable for data-acquisition units, control systems, and other devices with specialized functions, including one-of-a-kind designs.

To develop a device with a USB interface, you need to know something about how the interface works, what tasks your device firmware must perform to communicate on the bus, and what class drivers and other support are available on the host computers that your device will attach to. The right choices of device hardware, device class, and development tools and techniques can go a long way in avoiding snags and simplifying what needs to be done.

If you’re involved with designing USB devices, writing the firmware that resides inside USB devices, or writing applications that communicate with USB devices, this book will help you along the way.
