LTE Leverages New Wider Spectrum

Similar LTE and Evolved 3G PerformanceWhen using same bandwidth and same number of antennas

Best suited to leveragenew and wider contiguous spectrum

Available in smallerbandwidths

20 MHz15 MHz1.4MHz

10 MHz5 MHz3 MHz

LTE relative performance decreases with bandwidth due to higher overhead; 40% overhead in1.4 MHz vs. 25% in 20 MHz results in 25% better relative performance in 20 MHz vs. 1.4 MHz.
