HSPA+ is now available on more than 360 networks across about 160 countries, of which about 160 of the operators have already upgraded to dual-carrier HSPA+ (as of Feb 2014), which delivers peak downlink rates of 42 Mbps. The evolution continuous, bring in more carrier aggregation, HetNets enhancements, even more features to increase the capacity for bursty applications which are characteristic of smartphones and internet of everything (IoE) devices. With all the advancements of HSPA+ evolution, it is one of the important tools for operators to address the looming of 1000x data challenge.
