Comparison of LTE Speed

Major LTE Radio Technogies

•Uses Orthogonal Frequency Division Multiplexing (OFDM) for downlink

•Uses Single Carrier Frequency Division Multiple Access (SC-FDMA) for uplink

•Uses Multi-input Multi-output(MIMO) for enhanced throughput

•Reduced power consumption

•Higher RF power amplifier efficiency (less battery power used by handsets)
