Long Term Evolution-Advanced (LTE-Advanced) is a cellular networking standard that offers higher throughput than its predecessor, the Long Term Evolution (LTE) standard.
Long Term Evolution-Advanced networks can deliver up to 1 GB per second of data, compared to a maximum of 300 MB per second over LTE networks. Increasing demand for cellular bandwidth, however, means that carriers may use LTE-Advanced to increase their capacity, not necessarily to deliver significantly higher speeds. LTE-Advanced networks use multiple-input, multiple-output (MIMO) technology to deliver data faster via more than one signal. MIMO requires multiple antennas to receive those signals, which can limit its use in compact mobile devices such as smartphones and tablets.
Work on developing the LTE-Advanced standard began after the launch of the first LTE technologies, which did not meet the International Telecommunication Union (ITU) requirements for 4G. (The ITU subsequently lowered the bar for what qualifies as a 4G network.) The 3rd Generation Partnership Project finalized the LTE-Advanced standard in 2011, and it gained ITU approval in January 2012.
