全球性寬頻空白
2007年9月14日 · 由大衛布雷得里

期限「寬頻」變得同義與高速互聯網下載,但確切地多快是它? 學院的馬丁Fransman為日本歐洲技術研究,在愛丁堡大學,顯露怎麼關於寬頻發行和表現的數據可以是非常不同的根據您的地方。 日本和韓國顯著向前,当有些用戶下載在100兆每秒,比較速度在比那可以100次慢的歐洲和美國。 如果您是在一個繁忙的結離您的數字交換很遠,預算寬頻在英國比撥號實際上不快速。
「韓國顯然是全球性領先者根據寬頻滲透」,解釋Fransman在 技術學會,創新和發展國際定期刊物 (2007年, 1, 112-124)最近。 「日本」,他補充說, 「是全球性領導根據速度、先進技術,具體地纖維對這家價格和擴散」。
在根據銅連接的這些地區常規電信導線之外允許對寬頻通過DSL的通入。 所謂的「纜繩」寬頻依靠銅有線電視連接而不是光學纖維在網絡的用戶末端。 有一些超寬頻連接在將經營在每secondm 40吉比特是足够快速地下載完全高清晰度的DVD在二秒或如此的開發中,但它將是相當某個時候在那些之前進入主流。
Fransman,與許多政府和國際組織一起使用並且與主導的電信公司,包括AT&T, BT、法國電信、NTT、Ericsson、西門子、NEC和富士通,建議這被歪曲的發行寬頻橫跨被開發的世界困惑。
特別是,為什麼是它美國,介紹世界給互聯網,在寬頻,坐的第11滯後到目前為止後邊在世界上? 為什麼日本和韓國,在互聯網一般沒有被認為主要全球性球員,計算,軟件和微處理器,然而帶領世界在寬頻? 為什麼歐洲滯後後邊,不僅主導的亞洲國家,而且美國?
在他的研究論文Fransman解釋有經濟和技術挑戰到導致這不對稱的發行橫跨地球的普遍發展和舉起寬頻。 具體地,有三個交關解釋,他說。 這些取決於`破裂』競爭者扮演的角色和新加入者到商業市場裡為寬頻服務,推擠了價格下來在日本,例如和被強迫的速度增量和其他技術躍進。
Secondly, there is significant competition between the different technologies that might deliver broadband. There are various flavours of DSL (digital subscriber line), cable TV broadband, satellite, and WiFi. But in Japan, the very high-speed connections are made possible by fibre optic connections from the network direct to the users’ computers.
Finally, he points out that the strength of regulation in each country has a significant impact on broadband. In short, the telecommunications authorities in Japan, and to some extent in Korea also, are much tougher than their US and European counterparts. This has pushed the broadband providers to offer much more efficient and faster services in order to remain competitive and sustain their market share.
“These three causes of comparative international broadband performance themselves have complex institutional determinants,” concludes,” Fransman, “Unfortunately, deriving appropriate policy recommendations is no simple task.” Given how slowly technological legislation changes, this could mean that US and European internet users will be burdened with lower service quality and slower downloads compared to users in Japan and Korea for many years to come.

Phil Bradley (no relation) mentions how broadband is prevailing in the UK. Coincidentally, as I finished reading his post, a press release hit my inbox from the UK government department BERR. The government is now tackling the issue of rolling out ultrafast broadband across the UK. Bring it on. I am sick to the back teeth of 4Mbps.
