Mobile wireless communications are in constant evolution due to the continu- ously increasing requirements and expectations of both users and operators. Mass multimedia* services have been for a long time expected to generate a large amount of data traffic in future wireless networks [1]. Mass multimedia services are, by definition, purposed for many people. In general, it can be distinguished between the distribution of any popular content over a wide area and the distribu- tion of location-dependent information in highly populated areas. Representative examples include the delivery of live video streaming content (like sports compe- titions, concerts, or news) and file download (multimedia clips, digital newspa- pers, or software updates).

Never have telecommunications operations and network management been so important. Never has it been more important to move away from practices that date back to the very beginning of the telecommunications industry. Building and con- necting systems internally at low cost, on an as - needed basis, and adding software for supporting new networks and services without an overall architectural design will not be cost effective for the future. Defi ning operations and network manage- ment requirements at the 11th hour for new technologies, networks, and services deployments must also change.

In the past few decades, a technological revolution has occurred that has changed the way we live in dramatic ways. This technological revolution is the result of the emergence and evolution of a wide variety of new wireless networking tech- nologies. Now people using these technologies are able to access the network and control many applications at will with their handheld devices anywhere, anytime. Although these technologies have made a long lasting impact in the revolution, it has also opened up various challenging issues which are yet to be resolved to make them more efficient and cost-effective.

This chapter provides extensive coverage of existing mobile wireless technologies. Much of the emphasis is on the highly anticipated 3G cellular networks and widely deployed wireless local area networks (LANs), as the next-generation smart phones are likely to offer at least these two types of connectivity. Other wireless technologies that either have already been commercialized or are undergoing active research and standardization are introduced as well. Because standardization plays a crucial role in developing a new technology and a market, throughout the discussion standards organizations and industry forums or consortiums of some technologies are introduced. In addition, the last section of this chapter presents a list of standards in the wireless arena.

As we enter the next millennium, there are clear technological patterns. First, the electronic industry continues to scale microelectronic structures to achieve faster devices, new devices, or more per unit area. Secondly, electrostatic charge, electrostatic discharge (ESD), electrical overstress (EOS) and electromagnetic emissions (EMI) continue to be a threat to these scaled structures. This dichotomy presents a dilemma for the scaling of semiconductor technologies and a future threat to new technologies. Technological advancements, material changes, design techniques, and simulation can fend off this growing concern – but to maintain this ever-threatening challenge, one must continue to establish research and education in this issue.

The next avatar of the Internet will revolutionize our world. In time, it will provide us a universal remote control, enabling us to monitor and control physical objects located anywhere on the planet, using a smart phone. It will make the universe around us programmable, allowing us to script the behav- ior of physical objects with electronic commands. This book is about such an emerging new version of the Internet.

Building a robot and enabling it to sense its environment is a wonderful way to take your Arduino knowledge to the next level. In writing this book, I have brought together my love for invention and my experience with electronics, robotics and microcontrollers. I hope you have as much pleasure building and enhancing your robot as I did developing the techniques contained in this book.

Vivado設計分為Project Mode和Non-project Mode兩種模式，一般簡單設計中，我們常用的是Project Mode。在本手冊中，我們將以一個簡單的實驗案例，一步一步的完成Vivado的整個設計流程一、新建工程1、打開Vivado 2013.4開發工具，可通過桌面快捷方式或開始菜單中xilinx DesignTools-Vivado 2013.4下的Vivado 2013.4打開軟件，開啟后，軟件如下所示：2、單擊上述界面中Create New Project圖標，彈出新建工程向導，點擊next.3、輸入工程名稱、選擇工程存儲路徑，并勾選Create project subdirectory選項，為工程在指定存儲路徑下建立獨立的文件夾。設置完成后，點擊next注意：工程名稱和存儲路徑中不能出現中文和空格，建議工程名稱以字母、數字、下劃線來組成。4、選擇RTL Project一項，并勾選Do not specifty sources at this time，勾選該選項是為了跳過在新建工程的過程中添加設計源文件。點擊next.IA5、根據使用的FPGA開發平臺，選擇對應的FPGA目標器件。（在本手冊中，以xilinx官方開發板KC705為例，Nexys4開發板請選擇Artix-7 XC7A100TCSG324-2的器件，即Family和Subfamily均為Artix-7，封裝形式（Package）為cSG324，速度等級（Speed grade）為-1，溫度等級（Temp Grade）為C）。點擊next6、確認相關信息與設計所用的的FPGA器件信息是否一致，一致請點擊Finish，不一致，請返回上一步修改。二、設計文件輸入1、如下圖所示，點擊Flow Navigator下的Project Manager->Add Sources或中間Sources中的對話框打開設計文件導入添加對話框。2、選擇第二項Add or Create Design Sources，用來添加或新建Verilog或VHDL源文件，點擊next
