So how does LTE Advanced work? Glad you asked. It binds together "non-contiguous spectrum into a single, wider channel" which allows the carrier to be more efficient in handling data traffic. The plan is for AT&T to start rolling out this network even before it is finished with getting LTE to the front door of every Tom, Dick and Harry in the U.S. In the meantime, AT&T's LTE is in over 100 markets covering more than 150 million people. The mobile operator has already met its LTE target for the year which gives it the opportunity to stop and re-think its strategy. The carrier aims on reaching 250 million POPS with its LTE signal by the end of 2013 and 300 million by the end of 2014
AT&T had previously said that its LTE Advanced network would be in use next year, but has been stingy in providing details The service is considered an upgrade to the current LTE pipeline, bringing improvements in speed and capacity. According to Krisdh Prabhu, CEO and President of AT&T Labs, LTE Advanced provides users with speeds up to ten times faster than the current LTE service offers. More than a year ago, Sprint said that it would be offering LTE Advanced to its customers in the first half of 2013.
