HSPA+ Multiflow enables simultaneous transmission of two data streams from base stations in two adjacent cells to a single user device instead of one data stream from one base station as is the case with HSPA+today. Overall, this can up to double throughput (data speeds) for users at cell edge. Due to Nokia Siemens Networks’ highly scalable Single RAN equipment, operators can protect their earlier network investments, by evolving their existing HSPA networks to the new technology with a simple software upgrade.

“We are working with Nokia Siemens Networks to drive the evolution and deployment of technologies like HSPA+,” said Serge Willenegger, vice president of product management at Qualcomm. “This demonstration confirms that HSPA+ Multiflow will enable us to further enhance the HSPA+ mobile broadband user experience, and is thus a valuable contribution toward enhancing the HSPA+ value proposition and further expanding global mobile broadband coverage."

The HSPA+ Multiflow feature is expected to be 3GPP standardized by mid 2012, and will be available commercially from Nokia Siemens Networks by second half of 2013.
