Long Term Evolution (LTE) is the next generation of mobile broadband technology that provides higher data rates and network throughput compared to 3G. LTE networks use OFDM and SC-FDMA for downlink and uplink, respectively, along with MIMO and an all-IP architecture to improve performance. The network elements include eNBs, SGWs, PDN GWs and MMEs. For operators, LTE provides an opportunity to increase ARPU through new applications and services while decreasing CCPU through an all-IP infrastructure. Mass deployment of LTE is expected to begin around 2012, with LTE Advanced enabling data rates up to 1 Gbps.
