  • IEEE 1588网络时钟同步

    网络中基于IEEE 1588,由多个节点和多元化的连接,每个连接连接至少两个节点允许节点之间的通信,包括根据网络协议的消息交换,IEEE 1588的同步提高,允许多个主时钟系统中同时操作。为此,根据IEEE 1588标准,许多节点组成一个实现高可用性主时钟的子系统。

  • Deploying+Wireless+Networks

    At the time of writing, and to an extent never seen before, there is an expectation that almost any information or service that is available through communication systems in the office or home will be available wherever the user happens to be. This is placing incredible demands on wireless communications and has been the driver for the gen- esis and deployment of three generations of cellular systems in the space of 20 years.

  • Optical+Access+Networks

    The roots of this book were planted about a decade ago. At that time, I became increasingly convinced that wide-area and metropolitan-area networks, where much of my group’s research has been centered at that time, were in good shape. Although research in these fields was (and still is) needed, that’s not where the networking bottleneck seemed to be. Rather, the bottleneck was (and still is in many places) in the access networks, which choked users’ access to information and services. It was clear to me that the long-term solution to that problem has to involve optical fiber access networks.

  • Professional+Live+Communications+Server

    If you would like to follow along with some of the steps outlined in this book, we recommend that you deploy Live Communications Server 2005 SP1 on a physical or virtual server running Microsoft Windows Server 2003. To run Communicator 2005, you will need a physical or virtual PC running Windows XP or Windows Server 2003. To fully test Microsoft Office integration with Communicator 2005, you need to be running Microsoft Office 2003 with Service Pack 2.

  • Short-Range Wireless Communications

    Short-range communications is one of the most relevant as well as diversified fields of en- deavour in wireless communications. As such, it has been a subject of intense research and development worldwide, particularly in the last decade. There is no reason to believe that this trend will decline. On the contrary, the rapidly crystallizing vision of a hyper-connected world will certainly strengthen the role of short-range communications in the future. Concepts such as wireless social networks, Internet of things, car communications, home and office network- ing, wireless grids and personal communications heavily rely on short-range communications technology.

  • The+Telecommunications+Handbook

    Changes in telecommunications are impacting all types of user group, which include business users, traveling users, small and home offices, and residential users. The acceptance rate of telecom- munications and information services is accelerating significantly. Voice services needed approximately 50 years to reach a very high teledensity; television needed just 15 years to change the culture and lives of many families; the Internet and its related services have been penetrating and changing business practices and private com- munications over the last 2 to 3 years.

  • Wi-Fi(TM), Bluetooth(TM), Zigbee(TM) and WiMax(TM)

    Today wireless is becoming the leader in communication choices among users. It is not anymore a backup solution for nomadic travellers but really a newmoodnaturallyusedeverywhereevenwhenthewiredcommunicationsare possible. Many technologies evolve then continuously, changing the telecom- munication world. We talk about wireless local area networks (WLANs), wire- less personal area networks (WPANs), wireless metropolitan area networks (WMANs), wireless wide area networks (WWANs), mobile ad hoc networks (MANETs), wireless sensor networks (WSNs) and mesh networks. Since we can find today a multitude of wireless technologies we decided to group a numberofcomplementarytechnologiesintoonedocumenttomakeiteasierfor areadertounderstandsomeofthetechnicaldetailsofeachmedia.

  • ESD+and+Electronic+Equipment

    Since electronic equipment was first developed, static electricity has been a source of problems for users and designers. In the last few years, however, electrostatic discharge (ESD) has become a source of major problems. This has occurred because newer electronic devices, such as integrated circuits, are much more susceptible to ESD problems than previous devices, such as vacuum tubes. Another trend compounding this ESD susceptibility problem is the spread of sophisticated equipment into home and office environments where ESD is quite common.
