連DSL provider都受不了重度頻寬使用者：用量前5%的用戶使用46%的頻寬，而前1%的用戶佔去21%的頻寬！
前5%的用戶用量是其他95%用戶的5.2倍；前1%的用戶用量是其他99%用戶的26倍！以往並未考慮重度使用者的
Flat-fee，現今顯然讓運營商傷透腦筋，而未來3年總體頻寬需求將成長4倍！
計量收費似乎是一個可行的辦法，可是一般用戶無法了解『封包』的用意，容易因此卻步降低申辦意願，相信
這是運營商不敢輕易改用計量收費的原因之ㄧ吧。Mobile WiMAX遇到的狀況也差不多。Mobile WiMAX資費的設計的確需要好好的思考，因為專線與頻寬是OPEX+CAPEX中最大的成本項目。

AT&T Mulls Surcharge for High DSL Use
Robert Holmes
AT&T T is considering a surcharge for customers who go above the normal amount of downloaded data on the Internet.
AT&T spokesman Michael Coe says that given the trends the company is seeing, a form of usage-based pricing for those customers who have abnormally high usage patterns is "inevitable."
"Usage-based pricing is one way to deal fairly with Internet usage, which is very uneven among broadband users," he says.
The company's analysis of broadband users shows that a small percentage of customers use a large percentage of total bandwidth. The top 5% of consumer DSL subscribers use 46% of the total bandwidth, while the top 1% of subscribers are using 21% of bandwidth.
"Broadband use is surging," Coe says. "Based on current trends, total bandwidth in the AT&T network will increase by four times over the next three years."
Coe added that AT&T is currently evaluating broadband plans and services, but has nothing new to announce regarding pricing structure. Shares of AT&T were lately down 28 cents, or 0.8%, to $36.11.
While a usage surcharge is not expected to affect users who simply browse Web pages or check email, Internet subscribers who download high-definition movies from Apple's AAPL iTunes store or Netflix's NFLX download service could be subject to extra fees if they go over their quota.
Metered billing is not something new to telecom companies. Time Warner Cable TWC earlier this month said Internet users in
