Qualcomm and Ericsson, have successfully demonstrated Dual Carrier High Speed Uplink Packet Access (DC HSUPA) for the first time on a commercial smartphone.

The demo marks an important milestone in the continued evolution of 3G mobile communications technology, as DC-HSUPA can double the current maximum 3G uplink data rate.

Although most data consumption is asynchronous with more downloads than uploads, and most effort has gone into improving the download speed, with increasing social media content being generated by consumers, uploading photos and videos is becoming a more important area for operators, and consumers.

DC-HSUPA enables an uplink date rate of up to 11.5Mbps - double the current 3G maximum of 5.7Mbps. DC-HSUPA is expected to be commercially available in smartphones and tablets from leading manufacturers in Q2 of this year.

Qualcomm's Snapdragon 801 processor and its integrated multi-mode modem technology, powered the demonstration, which is being shown this week at Mobile World Congress.

"DC UL-HSPA is an important step in the continuing evolution of HSPA, providing up to twice the uplink speed for applications," said Nils Viklund, Vice President, Product Line WCDMA RAN at Ericsson. "Existing Ericsson customers benefit from this feature in software release WCDMA RAN W14B."
