The Telecommunications Revolution

A transformation is occurring that should greatly boost living standards in the developing world. Places that until recently were deaf and dumb are rapidly acquiring up-to-date telecommunications that will let them promote both internal and foreign investment. It may take a decade for many countries in Asia, Latin America, and Eastern Europe to improve transportation, power supplies, and other utilities. But a single optical fiber with a diameter of less than half a millimeter can carry more information than a large cable made of copper wires. By installing optical fiber, digital switches, and the latest wireless transmission systems, a parade of urban centers and industrial zones from Beijing to Budapest are stepping directly into the Information Age. A spider's web of digital and wireless communication links is already reaching most of Asia and parts of Eastern Europe.

All these developing regions see advanced communications as a way to leap over whole stages of economic development. Widespread access to information technologies, for example, promises to condense the time required to change from labor- intensive assembly work to industries that involve engineering, marketing, and design. Modern communications "will give countries like China and Vietnam a huge advantage over countries stuck with old technology".

How fast these nations should push ahead is a matter of debate. Many experts think Vietnam is going too far by requiring that all mobile phones be expensive digital models, when it is desperate for any phones, period. "These countries lack experience in weighing costs and choosing between technologies," says one expert.

Still, there's little dispute that communications will be a key factor separating the winners from the losers. Consider Russia. Because of its strong educational system in mathematics and science, it should thrive in the information age. The problem is its national phone system is a rusting antique that dates from the l930s. To lick this problem, Russia is starting to install optical fiber and has a strategic plan to pump $40 billion into various communications projects. But its economy is stuck in recession and it barely has the money to even scratch the surface of the problem.

Compare that with the mainland of China. Over the next decade, it plans to pour some $100 billion into telecommunications equipment. In a way, China's backwardness is an advantage, because the expansion occurs just as new technologies are becoming cheaper than copper wire systems. By the end of 1995, each of China's provincial capitals except for Tibet will have digital switches and high-capacity optical fiber links. This means that major cities are getting the basic infrastructure to become major parts of the information superhighway, allowing people to log on to the most advanced services available.

Telecommunications is also a key to Shanghai's dream of becoming a top financial center. To offer peak performance in providing the electronic data and paperless trading global investors expect, Shanghai plans telecommunications networks as powerful as those in Manhattan.

Meanwhile, Hungary also hopes to jump into the modern world. Currently, 700,000 Hungarians are waiting for phones. To partially overcome the problem of funds and to speed the import of Western technology, Hungary sold a 30% stake in its national phone company to two Western companies. To further reduce the waiting list for phones, Hungary has leased rights to a Dutch -Scandinavian group of companies to build and operate what it says will be one of the most advanced digital mobile phone systems in the world. In fact, wireless is one of the most popular ways to get a phone system up fast in developing countries. It's cheaper to build radio towers than to string lines across mountain ridges, and businesses eager for reliable service are willing to accept a significantly higher price tag for a wireless call — the fee is typically two to four times as much as for calls made over fixed lines.

Wireless demand and usage have also exploded across the entire width and breadth of Latin America. For wireless phone service providers, nowhere is business better than in Latin America — having an operation there is like having an endless pile of money at your disposal. BellSouth Corporation, with operations in four wireless markets, estimates its annual revenue per average customer at about $2,000 as compared to $860 in the United States. That's partly because Latin American customers talk two to four times as long on the phone as people in North America.

Thailand is also turning to wireless, as a way to allow Thais to make better use of all the time they spend stuck in traffic. And it isn't that easy to call or fax from the office: the waiting list for phone lines has from one to two million names on it. So mobile phones have become the rage among businesspeople, who can remain in contact despite the traffic jams.

Vietnam is making one of the boldest leaps. Despite a per person income of just $220 a year, all of the 300,000 lines Vietnam plans to add annually will be optical fiber with digital switching, rather than cheaper systems that send electrons over copper wires. By going for next-generation technology now, Vietnamese telecommunications officials say they'll be able to keep pace with anyone in Asia for decades.

For countries that have lagged behind for so long, the temptation to move ahead in one jump is hard to resist. And despite the mistakes they'll make, they'll persist — so that one day they can cruise alongside Americans and Western Europeans on the information superhighway.

    電信革命
    一個(gè)將會(huì)大大提高發(fā)展中國(guó)家生活水準(zhǔn)的轉(zhuǎn)變正方興未艾。 一些不久前還是信息閉塞的地方正在快速獲得最新的通信技術(shù),這將促進(jìn)當(dāng)?shù)貙?duì)國(guó)內(nèi)外投資的吸納。 亞洲、拉丁美洲和東歐的許多國(guó)家也許需要10年的時(shí)間來(lái)改善其交通、電力供應(yīng)和其他公用設(shè)施。 但是單單一根直徑小于半毫米的光纖電纜就可以比由銅絲制成的粗電纜負(fù)載更多的信息。 由于安裝了光纖電纜、數(shù)字轉(zhuǎn)換器和最新的無(wú)線傳輸系統(tǒng),從北京到布達(dá)佩斯的一系列城區(qū)和工業(yè)區(qū)正在直接跨入信息時(shí)代。 一個(gè)蛛網(wǎng)般的數(shù)字和無(wú)線通信網(wǎng)絡(luò)已經(jīng)伸展到亞洲的大部分地區(qū)和東歐的部分地區(qū)。
    所有這些發(fā)展中地區(qū)都把先進(jìn)的通信技術(shù)看作一種能跨越經(jīng)濟(jì)發(fā)展諸階段的方法。 例如,信息技術(shù)的廣泛應(yīng)用有望縮短從勞動(dòng)密集型的組裝工業(yè)轉(zhuǎn)向涉及工程、營(yíng)銷、設(shè)計(jì)等產(chǎn)業(yè)所需的時(shí)間。 現(xiàn)代通信技術(shù)將使像中國(guó)、越南那樣的國(guó)家與那些困于舊技術(shù)的國(guó)家相比擁有巨大的優(yōu)勢(shì)。
    這些國(guó)家應(yīng)以多快的速度向前發(fā)展是人們爭(zhēng)論的一個(gè)問(wèn)題。 許多專家認(rèn)為,越南在目前急需電話的情況下,卻要求所有的移動(dòng)電話都必須是昂貴的數(shù)字型電話的做法就是太超前了。 一位專家說(shuō),"這些國(guó)家缺乏估算成本和選擇技術(shù)的經(jīng)驗(yàn)。"
    然而毋庸?fàn)庌q,通信技術(shù)將是區(qū)分贏家和輸家的關(guān)鍵因素。 看一看俄羅斯的情況吧。 由于其堅(jiān)實(shí)的數(shù)學(xué)和科學(xué)教育基礎(chǔ),它應(yīng)該在信息時(shí)代有繁榮的發(fā)展。 問(wèn)題是,它的國(guó)內(nèi)電話系統(tǒng)是一堆生了銹的20世紀(jì)30年代的老古董。 為了解決這一問(wèn)題,俄國(guó)已經(jīng)開(kāi)始鋪設(shè)光纖電纜,并制定了投入400億美元建設(shè)多種通信工程的戰(zhàn)略計(jì)劃。 但是由于其經(jīng)濟(jì)陷于低迷,幾乎沒(méi)有資金來(lái)著手解決最基本的問(wèn)題。
    與俄國(guó)相比,在未來(lái)10年中,中國(guó)大陸計(jì)劃對(duì)通信設(shè)備投入1,000億美元。 從某種意義上說(shuō),中國(guó)的落后成了一種有利因素,因?yàn)檫@一發(fā)展正好發(fā)生在新技術(shù)比銅線電纜系統(tǒng)更便宜的時(shí)候。 到1995年底,中國(guó)除了西藏以外的省會(huì)都將有數(shù)字轉(zhuǎn)換器和高容量的光纖網(wǎng)。 這意味著其主要城市正獲得必需的基礎(chǔ)設(shè)施,成為信息高速公路的主要部分,使人們能夠進(jìn)入系統(tǒng),獲得最先進(jìn)的服務(wù)。
    通信工程也是上海實(shí)現(xiàn)其成為一流金融中心這一夢(mèng)想的關(guān)鍵。 為了能給國(guó)際投資者提供其所期望的電子數(shù)據(jù)和無(wú)紙化交易的出色服務(wù),上海計(jì)劃建設(shè)與曼哈頓的網(wǎng)絡(luò)同樣強(qiáng)大的遠(yuǎn)程通信網(wǎng)絡(luò)。
    與此同時(shí),匈牙利也希望躍入互聯(lián)網(wǎng)世界。 目前有70萬(wàn)匈牙利人等著裝電話。 為了部分地解決資金問(wèn)題, 加速輸入西方技術(shù),匈牙利將國(guó)有電話公司30%的股權(quán)出售給了兩家西方公司。 為進(jìn)一步減少電話待裝戶,匈牙利已將權(quán)利出租給一家荷蘭-斯堪的納維亞企業(yè)集團(tuán),來(lái)建造并經(jīng)營(yíng)一個(gè)據(jù)說(shuō)是世界上最先進(jìn)的數(shù)字移動(dòng)電話系統(tǒng)。 事實(shí)上,無(wú)線方式是在發(fā)展中國(guó)家快速建起電話系統(tǒng)的最受歡迎的方式之一。 建造無(wú)線電發(fā)射塔要比翻山越嶺架設(shè)線路更便宜。 而且,急切想得到可靠服務(wù)的企業(yè)樂(lè)于花費(fèi)可觀的高價(jià)來(lái)?yè)Q取無(wú)線電話--通常是固定線路電話資費(fèi)的二至四倍。
    整個(gè)拉丁美洲對(duì)無(wú)線通信的需求和使用已急速增加。 對(duì)于無(wú)線電話服務(wù)商來(lái)說(shuō),沒(méi)有任何地方的業(yè)務(wù)比拉丁美洲更好了--在那里有一個(gè)營(yíng)運(yùn)點(diǎn)就好像有一堆無(wú)窮無(wú)盡供你使用的鈔票。 在四個(gè)無(wú)線電話市場(chǎng)有營(yíng)運(yùn)點(diǎn)的貝爾南方電話公司估計(jì)它的年收入約為平均每個(gè)客戶2,000美元,與之相比,在美國(guó)國(guó)內(nèi)的收入是860美元。 產(chǎn)生這種情況的部分原因是拉丁美洲客戶的通話時(shí)間是北美洲人的二至四倍。
    泰國(guó)也在求助于無(wú)線通信方式,以便讓泰國(guó)人在發(fā)生交通堵塞的時(shí)候更好地利用時(shí)間。 而且在泰國(guó),從辦公室往外打電話或發(fā)傳真并不那么容易:待裝電話的名單上有一、二百萬(wàn)個(gè)名字。 因此移動(dòng)電話在商界成為時(shí)尚,使人們?cè)诮煌ǘ氯麜r(shí)也能與外界保持聯(lián)系。
    越南正在做出一個(gè)最大膽的跳躍。 盡管越南人均年收入只有220美元,它計(jì)劃每年增加的30萬(wàn)條線路將全部為有數(shù)字轉(zhuǎn)換的光纖電纜,而不是那些以銅線傳送電子信號(hào)的廉價(jià)系統(tǒng)。 由于現(xiàn)在就選用了下一代的技術(shù),越南負(fù)責(zé)通信的官員說(shuō)他們能夠在數(shù)十年中與亞洲的任何一個(gè)國(guó)家保持同步。
    對(duì)于那些長(zhǎng)期落后的國(guó)家來(lái)說(shuō),一躍而名列前茅的誘惑難以抵御。 而且,盡管他們會(huì)犯錯(cuò)誤,他們?nèi)詴?huì)堅(jiān)持不懈--總有一天,他們將能在信息高速公路上與美國(guó)和西歐并駕齊驅(qū)。
