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
    一個將會大大提高發(fā)展中國家生活水準的轉變正方興未艾。 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,這將促進當地對國內外投資的吸納。 亞洲、拉丁美洲和東歐的許多國家也許需要10年的時間來改善其交通、電力供應和其他公用設施。 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載更多的信息。 由于安裝了光纖電纜、數字轉換器和最新的無線傳輸系統(tǒng),從北京到布達佩斯的一系列城區(qū)和工業(yè)區(qū)正在直接跨入信息時代。 一個蛛網般的數字和無線通信網絡已經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)都把先進的通信技術看作一種能跨越經濟發(fā)展諸階段的方法。 例如,信息技術的廣泛應用有望縮短從勞動密集型的組裝工業(yè)轉向涉及工程、營銷、設計等產業(yè)所需的時間。 現代通信技術將使像中國、越南那樣的國家與那些困于舊技術的國家相比擁有巨大的優(yōu)勢。
    這些國家應以多快的速度向前發(fā)展是人們爭論的一個問題。 許多專家認為,越南在目前急需電話的情況下,卻要求所有的移動電話都必須是昂貴的數字型電話的做法就是太超前了。 一位專家說,"這些國家缺乏估算成本和選擇技術的經驗。"
    然而毋庸爭辯,通信技術將是區(qū)分贏家和輸家的關鍵因素。 看一看俄羅斯的情況吧。 由于其堅實的數學和科學教育基礎,它應該在信息時代有繁榮的發(fā)展。 問題是,它的國內電話系統(tǒng)是一堆生了銹的20世紀30年代的老古董。 為了解決這一問題,俄國已經開始鋪設光纖電纜,并制定了投入400億美元建設多種通信工程的戰(zhàn)略計劃。 但是由于其經濟陷于低迷,幾乎沒有資金來著手解決最基本的問題。
    與俄國相比,在未來10年中,中國大陸計劃對通信設備投入1,000億美元。 從某種意義上說,中國的落后成了一種有利因素,因為這一發(fā)展正好發(fā)生在新技術比銅線電纜系統(tǒng)更便宜的時候。 到1995年底,中國除了西藏以外的省會都將有數字轉換器和高容量的光纖網。 這意味著其主要城市正獲得必需的基礎設施,成為信息高速公路的主要部分,使人們能夠進入系統(tǒng),獲得最先進的服務。
    通信工程也是上海實現其成為一流金融中心這一夢想的關鍵。 為了能給國際投資者提供其所期望的電子數據和無紙化交易的出色服務,上海計劃建設與曼哈頓的網絡同樣強大的遠程通信網絡。
    與此同時,匈牙利也希望躍入互聯網世界。 目前有70萬匈牙利人等著裝電話。 為了部分地解決資金問題, 加速輸入西方技術,匈牙利將國有電話公司30%的股權出售給了兩家西方公司。 為進一步減少電話待裝戶,匈牙利已將權利出租給一家荷蘭-斯堪的納維亞企業(yè)集團,來建造并經營一個據說是世界上最先進的數字移動電話系統(tǒng)。 事實上,無線方式是在發(fā)展中國家快速建起電話系統(tǒng)的最受歡迎的方式之一。 建造無線電發(fā)射塔要比翻山越嶺架設線路更便宜。 而且,急切想得到可靠服務的企業(yè)樂于花費可觀的高價來換取無線電話--通常是固定線路電話資費的二至四倍。
    整個拉丁美洲對無線通信的需求和使用已急速增加。 對于無線電話服務商來說,沒有任何地方的業(yè)務比拉丁美洲更好了--在那里有一個營運點就好像有一堆無窮無盡供你使用的鈔票。 在四個無線電話市場有營運點的貝爾南方電話公司估計它的年收入約為平均每個客戶2,000美元,與之相比,在美國國內的收入是860美元。 產生這種情況的部分原因是拉丁美洲客戶的通話時間是北美洲人的二至四倍。
    泰國也在求助于無線通信方式,以便讓泰國人在發(fā)生交通堵塞的時候更好地利用時間。 而且在泰國,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、二百萬個名字。 因此移動電話在商界成為時尚,使人們在交通堵塞時也能與外界保持聯系。
    越南正在做出一個最大膽的跳躍。 盡管越南人均年收入只有220美元,它計劃每年增加的30萬條線路將全部為有數字轉換的光纖電纜,而不是那些以銅線傳送電子信號的廉價系統(tǒng)。 由于現在就選用了下一代的技術,越南負責通信的官員說他們能夠在數十年中與亞洲的任何一個國家保持同步。
    對于那些長期落后的國家來說,一躍而名列前茅的誘惑難以抵御。 而且,盡管他們會犯錯誤,他們仍會堅持不懈--總有一天,他們將能在信息高速公路上與美國和西歐并駕齊驅。
