Of all the confusing technology terms used in consumer marketing today, perhaps the most opaque is '4G,' used to describe a new, much faster generation of cellular data on smartphones, tablets and other devices. It sounds simple, but there are many varieties of 4G and conflicting claims.
如今，在消费品营销领域种种令人费解的技术名词中，最含混不清的或许就是"4G"了，4G被用来描述智能手机、平板电脑等设备使用的新一代速度更快的蜂窝数据技术。这个概念听起来很简单，但4G有很多种类，有关4G的说法也有自相矛盾之处。
AT&T claims 'The nation's largest 4G network,' and T-Mobile says it has 'America's largest 4G network.' Verizon Wireless boasts 'America's fastest 4G network,' and Sprint says it had the first 4G network.
美国电话电报公司(AT&T)号称有"全美最大的4G网络"，T-Mobile也自称拥有"美国最大的4G网络"。Verizon Wireless自诩"美国最快的4G网络，"而Sprint则说自己拥有美国首个4G网络。
Yet the technology used by T-Mobile, and mostly comprising AT&T's 4G network, isn't considered 'real' 4G at all by some critics, and the one used by Sprint has proven to be a dead end and is being abandoned. The flavor being used by Verizon is now being adopted by its rivals, but won't be interoperable among them.
然而，在部分评论人士看来，T-Mobile使用的技术以及美国电话电报公司大多数4G网络采用的技术根本不是"真正的"4G，Sprint使用的4G技术已证明是行不通的，行将放弃。Verizon使用的4G技术目前正逐渐被其竞争对手采用，但运营商之间无法互通。
It's a headache for consumers to grasp. So here's a simplified explainer to some of the most common questions, based on interviews with top technical officials at all four major U.S. wireless carriers.
这些东西让消费者理解起来很困难。那么，现在我将根据对这四家美国主要无线运营商技术高管的采访，对一些最常见的问题做出简单的解释。
