Expected to cross 1 billion connections in 2012, HSPA family has grown to be the undisputed leader in mobile broadband technology. With HSPA+ becoming the new baseline, and operators moving toward dual-carrier HSPA+, Qualcomm is again leading the industry with HSPA+ Advanced that takes the performance of HSPA+ to the next level. It incorporates a variety of innovative techniques, many of which have already been prototyped and demonstrated by Qualcomm.
Utilizing unused capacity to increase overall performance
Introducing innovative techniques such as "MultiFlow" to exploit inherently uneven network load that changes with time and location. MultiFlow dynamically balances network load and offers higher overall capacity as well as better data rates for user at the edge of the cell.
Multicarrier evolution—leveraging all spectrum assets
Multicarrier means more speed and capacity for all users. HSPA+ evolution expands multicarrier in many directions. It defines more spectrum band combinations and supports aggregation of up to 8 carriers. Most importantly, to increase the downlink capacity, it enables "Supplemental Downlink (SDL)." SDL combines the unpaired spectrum with paired spectrum.
Optimizing small cells/ HetNets
Today’s networks are getting more heterogeneous, with the increasing addition of small cells such as picocells. HSPA+ evolution incorporates optimizations such as “Range Expansion” that increase the utilization of small cells, improve the overall network capacity, and enhance data rates for users at the cell-edge. Range Expansion is possible today. HSPA+ Advanced further enhances it.
More advanced antenna techniques
Bringing MIMO to the uplink, and further evolving downlink MIMO. But, most importantly, introducing uplink closed loop beamforming to provide better coverage and capacity to modern uplink-heavy applications.
Enabling billions of connected devices
Bracing for the next explosion—think billions—of interconnected, low-traffic machine-to-machine devices and the continued growth of smartphones, HSPA+ Advanced has optimizations to provide more than ten-fold capacity for carrying small data bursts for such devices.
