It's like calling Vitamin Water a health food. Marketers are allowed to call it whatever they want, but the truth is that Vitamin Water is full of sugar, which isn't all that healthy.

This is the technology currently supported in the new iPad. And it's likely to be supported in the next version of the iPhone, which I expect will be introduced later this year.

The reason that LTE and WiMax have been considered 4G is that they are based on a new type of network technology that is more efficient than previous 3G technologies. LTE and WiMax also differ from traditional cell phone technology because these networks are exclusively data-centric. While traditional cellular networks, have a separate voice network, WiMax and LTE will offer voice service over the data network, much like VoIP services like Skype or Vonage operate on a traditional broadband network.

Treating voice as just another data application on the network allows for more efficient use of the wireless spectrum and network resources. And this is a big reason why carriers are switching to these "4G" network technologies. But 4G wireless technologies are also supposed to bring much faster upload and download speeds to the network.

But the truth is that none of them live up to the official definition that has been established by the International Telecommunications Union, an international telecom standards setting body within the United Nations.

Today's WiMax standard has the potential to achieve theoretical downloads of 40 Mbps. And LTE can achieve speeds of Mbps. There are updates to each of these standards coming.

T-Mobile had been late to the 3G market. But they're not being entirely honest either. For you. World globe An icon of the world globe, indicating different international options. Get the Insider App.
