最后一公里

• The system will offer an tool to solve " the last kilometer " problem of science & technology information service in countryside and to strengthen university ' s development ability in china , especially in rural area
  系统的构建为面向基层农村解决科技信息服务“最后一公里”问题和运用信息手段加强我国高校发展能力建设提供了有益的参考。
• Moreover the questions such as the laying speed of copper hawser is slow and period is long make that " final one kilometer " of between the exchanger and user terminal has become restricting his follow - on bottle of neck question
  另外，铜缆的敷设速度慢、周期长等问题，使得交换机到用户终端之间的“最后一公里”已成为制约其发展的瓶颈问题。
• And with the great progress of backbone networks construction in china , it is the broadband access that has become the most important problem , which is well - known as the " last mile "
  而随着我国主干网的建设日趋完善，如何直接向用户提供高速、可靠、低成本的宽带网络接入已成为网络建设的主要问题，这也就是长期困扰着通信行业的“最后一公里”的问题。
• Broadband wireless access technology is one of the main developmentes for broadband communication in 21 century . it is the pivotal technology to solve the problem of “ last one kilometer ” access and “ bandwidth bottleneck ” for 3g mobile users
  宽带无线接入技术是21世纪宽带通信技术的主要发展方向之一,是解决“最后一公里”接入问题、第三代个人移动通信用户“带宽瓶颈”问题的关键技术。
• But between the lan and backbone is provided by much lower bandwidth technologies available through the existing copper wire , adsl , cable modem , and the " last mile " ( between the lan and fiber backbone ) problem has become a bottle - neck in the wideband transmission
  但是光纤干线和局域网间接入系统却是传统的铜缆、 adsl 、同轴电缆等，传输速率都在10mbps以下。所以光纤和局域网间“最后一公里”的接入成为解决宽带传输的瓶颈问题。
• Since 2000 , the construction of a broadband information network has gradually become a hot point in the development of data communications network , resulting in many network carriers setting feet on this area . broadband access network as a means to break the " last mile " access bottleneck has become a de facto key concern in the broadband field
  自从2000年以来，宽带信息网络的建设，已经逐步成为了数据网络建设的一个热点，诸多的网络运营商纷纷涉足这个领域。作为解决用户接入“最后一公里”问题的宽带接入网实际上已经成为宽带网络的主要问题。
• Moreover , the limited use of broadband services within communities will hinder their further development . nevertheless , since communities cover the " last miles " of the connections from the broadband networks to the end users and some communities have even done integrated wiring in their " last miles " , they are an important force in deploying broadband services
  另外，仅仅局限在社区内部使用的宽带业务是不会有太大发展的。社区覆盖了宽带网络到最终用户这最后一公里的地域范围，而且有的社区还进行了这最后一公里的综合布线，因此社区是开展宽带业务的重要力量。
• The normal user must go through the access network and backbone to access the internet via icp there are always high - rate and broadband lines connected to the backbone , the backbone of telecom can provide wide enough bandwidth for all the data transmission as more and more optic fiber with wdm and dwdm technologies have been paved . but " the last mile " from user ' s home to central office is still narrow - band and analog , which becomes bottom - neck of the communication subnet preventing it from being widen
  一般用户使用internet时要经过接入网，电信主干网，最后达到icp ( internetcontentprovider ：因特网内容提供商) 。其中icp一般有着高速宽带的线路与主干网相连，而主干网由于波分复用或密集波分复用的光纤技术的大量使用，使得其可提供足够的带宽使用，但是，接入网? ?从用户家庭到电信网的局端的这“最后一公里” ，仍然是窄带的、模拟的，这“最后一公里”就是电信网宽带化的瓶颈。
• Epon ( ethernet passive optical network ) technology represents the convergence of mature ethernet technology with pon and is regarded as the best candidate technology of next generation access network because of its low - cost , broad bandwidth , simple maintenance , excellent performance - to - cost ratio and providing multi - service
  它综合了无源光网络pon技术和以太网技术的优点,具有成本低、兼容性好、技术成熟、便于维护、承载业务灵活等特点,成为解决接入网“最后一公里”问题的下一代宽带接入网的最佳方案之一。
• By integrating all the latest information and active form gateway technology , the project connected the wireless communicating network , telephone network and internet to realize the alete bonding of information and widening the service scope of application system based on internet , thus the farmer could get the information from internet more delicacy and effectively , which will solve the " the lastly one mile " problem of fruiter information transferring
  摘要本项目综合运用各种最新的信息技术以及主动式网关技术，将无线通讯网、固定电话网和互联网络连接在一起，实现信息的无缝跨接，拓宽了互联网络上应用系统的服务范围，使得基层农户能够以灵活方便的形式获得互联网络上的信息，有效的解决了果树信息传递的“最后一公里问题” 。
