一位英特爾(Intel)高層表示，在日本于3月11日發(fā)生的里9.0強(qiáng)震中，WiMax 技術(shù)已被證實比 3G 蜂巢式技術(shù)更具可靠性。
發(fā)表以上言論的是英特爾副總裁暨嵌入式計算機(jī)事業(yè)群總經(jīng)理Ton Steenman，在日本大地震發(fā)生前一刻，他人就在當(dāng)?shù)?；?G手機(jī)網(wǎng)絡(luò)在地震中幾乎完全中斷，但 WiMax 網(wǎng)絡(luò)卻屹立不搖、并持續(xù)在各種應(yīng)用中運(yùn)作；包括自動提款機(jī)(ATM)、數(shù)字看板等等，有不少服務(wù)都是藉由WiMax網(wǎng)絡(luò)所提供?！盨teenman表示。
目前最新版的WiMax可提供40Mbit/s的傳輸速率，而預(yù)期IEEE 802.16m的更新版本，可將速率提升到1Gbit/s。
當(dāng)被問到WiMax網(wǎng)絡(luò)經(jīng)證實的強(qiáng)韌度，是否有助于該技術(shù)在市場上與 LTE 等 4G 技術(shù)競爭？Steenman表示：“你可能認(rèn)為蜂巢式通訊技術(shù)已經(jīng)邁向3G，但其實世界上大多數(shù)地區(qū)仍在采用GSM等其它2G技術(shù)；4G-LTE時代還要5~10年才會來臨，而WiMax已經(jīng)存在，且在全球取多區(qū)域都有很好的覆蓋率?！?
Steenman的結(jié)論是：“WiMax是非常強(qiáng)韌的通訊技術(shù)，我們預(yù)期將持續(xù)看到該技術(shù)成功拓展其市場?！?

WiMax survived Japan quake, says Intel exec
Peter Clarke
SHANNON, Ireland – WiMax wireless LAN technology has proved more resilient than 3G cellular technology during the earthquake that hit Japan last Friday (March 11) and its aftermath, according to an Intel executive.
Ton Steenman, vice president and general manager of the embedded computer group at Intel, said he had been in Japan immediately prior to the earthquake. "The 3G phone network completely broke down. The WiMax network stayed up and running throughout all the issues that Japan has had during the last week. ATMs [automated teller machines] and digital signage are often connected through WiMax. A lot of services are overlaid on WiMax."
The current WiMAX revision provides up to 40-Mbit/s with the IEEE 802.16m update expected to offer up to 1-Gbit/s fixed speeds.
When asked if he thought the robustness demonstrated by WiMax would help with its market acceptance in competition against 4G-LTE, Steenman said: "You may think that the cellular world has moved to 3G but most of the world runs on GSM and other 2G technologies. 4G-LTE will come in 5 to 10 years. WiMax is here today and has very good coverage in many geographic areas."
Steenman concluded: "WiMax is a very robust communications technology. We will continue to see that success grow."
