Samsung succeeded in demonstrating High-Speed Uplink Packet Access (HSUPA) systems and mobile phones at ITU Telecom World 2006. HSUPA is the enhanced version of WCDMA, offering higher data communication speeds for uplink. With HSUPA networks, users can upload and receive photos, video clips, data files, and share contents more easily with their friends and family members.

At the demonstration, Samsung's network equipment and mobile phones reached speeds up to 2 Mbps for uplink and 3.6Mbps for downlink. The speed demonstrated is capable of handling large scale of data communications such as video streaming and ftp file transferring. Comparing with current WCDMA upload speed, the HSUPA demo is 5 times faster. For example, it takes 1 minute to upload 5 MP3 songs (assuming 3 Mega Byte per song) under HSUPA circumstance, while it took 5 minutes to upload the 5 MP3 songs under WCDMA.

Samsung plans to introduce the first commercial HSUPA phone in Europe by 2007. Orange will be one of Samsung's earliest partners for HSUPA deployment.
