奥瑞尔和范法伦的研究表明，将发展中地区的移动宽带普及度提高两倍 — — 从21%提高到60 % — —需要花费大约1.3万亿美元巨资，因为要增加三十亿个互联网连接需要大量新增基础设施。
The study by Auriol and Fanfalone shows that increasing mobile broadband about three-fold in developing regions – from 21% to 60% – will cost a substantial $1.3 trillion, as a significant amount of extra infrastructure is needed to establish about three billion more Internet connections.
