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 perform ance in 20 MHz vs. 1.4 MHz.

Qualcomm: Continued Standards Leadership

Notes 1Based on pre-meeting contribution count for 3GPP RAN WG4 (in charge of performance requirements) . 2E.g. for femtocells and positioning across all working groupsand areas. Examples of features such as Mobility, access control, local IP access, system definition, security . 3for single point transmission results, also showed that thatNetwork-MIMO/CoMP techniques were not required to satisfy those requirements.

A leading contributor for LTE performancedefinition in 20091

Leader in several key LTE standards areas2

A Main contributor to key LTE Advanced features Carrier aggregation, self-organizing network, relay, waveform

Major contributor for ITU IMT-Advanced submission First company to show results satisfying IMT-Advanced requirements3
