How fast can High Speed Packet Access Evolution (HSPA+) reach in terms of data speed?

High Speed Packet Access Evolution (HSPA+) is a mobile broadband technology that significantly enhances the capabilities of the older HSPA standard. It provides increased data rates by utilizing advanced modulation schemes and higher order MIMO (Multiple Input, Multiple Output) configurations.

The maximum theoretical data speed achievable with HSPA+ can reach up to 42 Mbps under optimal conditions. However, in some network implementations and configurations, certain versions of HSPA+ may also report speeds in the range of 50 Mbps. This demonstrates the capability of HSPA+ to deliver a substantially faster and more efficient mobile internet experience compared to earlier technologies, making mobile data connectivity more viable for bandwidth-intensive applications.

The other options indicate lower speeds, which reflect earlier standards or technologies that do not represent the enhanced capabilities of HSPA+.
