ATT 4G AT&T的第四代网络不像威瑞森（Verizon）的移动通信网络那样分布广泛（前者覆盖171个美国城市，后者为486个），但随着这个美国头号无线网络运营商扩大其足迹，这种情况将发生改变。4G网速是3G的10倍，在移动设备上实现了更快的网页载入、文件下载和流畅的高清视频播放。随着4G覆盖面的扩大，更多用户将采用它，网络表现的大幅改善将让他们以前所未有的方式来使用他们的设备。 |
ATT 4G AT&T's fourth-generation network may not be as widespread as Verizon's (171 U.S. markets versus 486), but expect that to change as the number one domestic wireless carrier expands its reach. With speeds up to 10 times that of 3G, 4G performance allows brisker loading of web pages, fast file downloads, and smooth streaming of high-definition video on a mobile device. As 4G coverage expands, more users will adopt it, and vast improvement in network performance will let them use their devices in way they hadn't before. |
