LTE-Advanced (4G) is a 3GPP standard that describes technological advancements to the Long Term Evolution (LTE) a highly flexible radio interface that aims at bridging the gap between 3rd generation and 4th Generation (4G) standards. LTE Advanced does meet most of the standards for 4G deployment, though it is often described as 3.9G or pre-4G. This paper presents a general comparison study between LTE (3.9G) and LTE-Advanced (4G) in terms of its capable of peak download data rates of 1 Gbps, wide transmission bandwidth, low C-plane latency, increased user throughput and spectrum flexibility.
