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.
