The “first reference publication” date used is the earliest publication date where Qualcomm feels that a set of reasonably complete and consistent specifications were available. Note that the LTE air interface publication date shown is 12/2007, but the core network (EPC) was published mid 2008. A stable ASN.1 code is required for commercial implementation of the standard (LTE R8 ASN.1 was frozen in March 2009).

Best suited to leverage new and wider bandwidths

Available in smaller bandwidths

20 MHz15 MHz1.4MHz 10 MHz5 MHz3 MHz

3G CoverageSeamless 3G service continuity from day one—Evolved 3G ensures similar user experience

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