Wireless Communications＊byJoshua S。
Gans，Stephen P。
King and Julian Wright1. IntroductionIn 1895, Guglielmo Marconi opened the way for modern wireless communications by transmitting the three—dot Morse code for the letter ‘S’ over a distance of th ree kilometers using electromagnetic waves。
From this beginning，wireless communications has developed into a key element of modern society. From satellite transmission, radio and television broadcasting to the now ubiquitous mobile telephone，wireless communications has revolutionized the way societies function.This chapter surveys the economics literature on wireless communications。
Wireless communications and the economic goods and services that utilise it have some special characteristics that have motivated specialised studies。
First, wireless communications relies on a scarce resource –namely，radio spectrum –the property rights for which were traditionally vested with the state. In order to foster the development of wireless communications (including telephony and broadcasting）those assets were privatised。

5G无线通信网络中英文对照外文翻译文献
5G无线通信网络中英文对照外文翻译文献(文档含英文原文和中文翻译)翻译：5G无线通信网络的蜂窝结构和关键技术摘要第四代无线通信系统已经或者即将在许多国家部署。
然而，随着无线移动设备和服务的激增，仍然有一些挑战尤其是4G所不能容纳的，例如像频谱危机和高能量消耗。
无线系统设计师们面临着满足新型无线应用对高数据速率和机动性要求的持续性增长的需求，因此他们已经开始研究被期望于2020年后就能部署的第五代无线系统。
在这篇文章里面，我们提出一个有内门和外门情景之分的潜在的蜂窝结构，并且讨论了多种可行性关于5G无线通信系统的技术，比如大量的MIMO技术，节能通信，认知的广播网络和可见光通信。
面临潜在技术的未知挑战也被讨论了。
介绍信息通信技术（ICT）创新合理的使用对世界经济的提高变得越来越重要。
无线通信网络在全球ICT战略中也许是最挑剔的元素，并且支撑着很多其他的行业，它是世界上成长最快最有活力的行业之一。
欧洲移动天文台（EMO）报道2010年移动通信业总计税收1740亿欧元,从而超过了航空航天业和制药业。
无线技术的发展大大提高了人们在商业运作和社交功能方面通信和生活的能力无线移动通信的显著成就表现在技术创新的快速步伐。
从1991年二代移动通信系统(2G)的初次登场到2001年三代系统（3G）的首次起飞，无线移动网络已经实现了从一个纯粹的技术系统到一个能承载大量多媒体内容网络的转变。
4G无线系统被设计出来用来满足IMT-A技术使用IP面向所有服务的需求。
在4G系统中，先进的无线接口被用于正交频分复用技术（OFDM），多输入多输出系统（MIMO）和链路自适应技术。
4G无线网络可支持数据速率可达1Gb/s的低流度，比如流动局域无线访问，还有速率高达100M/s的高流速，例如像移动访问。
LTE系统和它的延伸系统LTE-A，作为实用的4G系统已经在全球于最近期或不久的将来部署。
然而，每年仍然有戏剧性增长数量的用户支持移动宽频带系统。
美国三大运营商2013 LTE部署详解
美国四大运营商2013年LTE网络部署进程详解2013年08月21日 11:09 C114中国通信网我有话说C114讯8月21日早间消息(艾斯)现在进入美国市场的终端，很少有不支持LTE服务的。
美国是全球最先进的LTE市场之一，其他走在LTE发展前列的国家还包括韩国与日本等国家。
如果我们相信运营商预测数值的话，那么到2013年底将会有4家美国无线运营商的LTE网络都能达到至少2亿人口的覆盖水平。
尽管网络没有覆盖到所有美国人口，并且运营商的覆盖强度各异，但是相较于2013年初，情况已经好了很多。
带着所有这些问题，FierceWireless发布了美国LTE市场的进展概况，主要关注于四家Tier 1运营商。
当然，一些规模较小的运营商也已推出了LTE网络，但是没有一家的网络可与Tier 1运营商匹敌。
自去年秋季以来，美国无线市场发生了很大的变化：一些运营商已经被收购了(MetroPCS)，还有一些运营商则正在被收购的过程中(Leap Wireless)。
总体来看，Verizon Wireless 在LTE人口覆盖和网络承载数据流量方面继续引领市场。
Verizon正享受着领先地位，该运营商于2010年商用了其LTE网络。
但是这并不意味着Verizon的竞争对手在坐以待毙。
进入2013年以来，AT&T Mobility一直在疯狂扩大其LTE覆盖范围，并且该运营商计划到2013年底实现与Verizon不相上下的LTE覆盖。
Sprint的部署已经落后于其竞争对手，但是现在该运营商已经收到了来自母公司软银的资金，Sprint计划在全国范围内部署Clearwire的2.5 GHz频谱用于TD-LTE服务，希望借此增加网络容量。
而在今年3月才商用LTE服务的T-Mobile美国，目前其LTE网络已经覆盖了1.57亿人口。
T-Mobile美国CEO John Legere表示，该公司有望在原定的截止日期(今年年底)前完成2亿人口的覆盖目标。
光纤通信发展的历史和现状
2.5dB/km。1974 年降低到1.1dB/km。
• 1976 年，日本电报电话(NTT)公司将光纤损耗降低到0.47
dB/km(波长1.2μm)。
• 在以后的 10 年中，波长为1.55 μm的光纤损耗：
这种方案技术简单，成本较低，容易实现，但调制速率 受激光器的频率特性所限制。
外调制
把激光的产生和调制分开，用独立的调制器调制激光器的 输出光而实现的。
外调制的优点是调制速率高，缺点是技术复杂，成本较高， 因此只有在大容量的波分复用和相干光通信系统中使用。

指明通过“原材料的提纯制造出适合于 长距离通信使用的低损耗光纤”这一发展方 向
光纤通信发明家高锟(左) 1998年在英国接受IEE授予的奖章
1970年，光纤研制取得了重大突破
• 1970年，美国康宁(Corning)公司研制成功损耗20dB/km的
石英光纤。把光纤通信的研究开发推向一个新阶段。
• 1972年，康宁公司高纯石英多模光纤损耗降低到4 dB/km。
光纤可以传输数字信号，也可以传输模拟信号。光纤在通 信网、广播电视网与计算机网，以及在其它数据传输系统中， 都得到了广泛应用。光纤宽带干线传送网和接入网发展迅速， 是当前研究开发应用的主要目标。
光纤通信的各种应用可概括如下：
① 通信网
② 构成因特网的计算机局域网和广域网
③ 有线电视网的干线和分配网
④ 综合业务光纤接入网
1979 年是0.20 dB/km，1984年是0.157 dB/km，1986 年是 0.154 dB/km， 接近了光纤最低损耗的理论极限。
