This document summarizes the evolution of HSPA+ technology over multiple releases. It shows how HSPA+ utilizes techniques like multicarrier, carrier aggregation, MIMO, and small cells to significantly increase data rates over time. These techniques, combined with optimizations for heterogeneous networks and machine-to-machine communication, will help HSPA+ meet the 1000x mobile data challenge. Qualcomm has played a leadership role in advancing HSPA+ technology through contributions to standards and industry-first chipsets and demonstrations.
