Qualcomm: Continued LTE 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 groups and areas . Examples of features such as Mobility, access control, local IP access, system definition, security . 3for single point transmission results, also showed that that Network-MIMO/CoMP techniques were not required to satisfy those requirements.

A leading contributor for LTE performance definition in 20091

Leader in several key LTE standards areas2

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

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