At this week’s PT Expo Comm in Beijing, Nokia Siemens Networks is demonstrating a multi-band, multi-carrier HSPA+ data call with peak throughput of 336 Mbps. 
The demo uses the company’s commercial Flexi Multiradio Base Station and Multicontroller platform alongside MDM8220 test terminals from Qualcomm. It combines a total of eight HSPA carriers (multi-carrier), each carrying 42 Mbps with MIMO and 64 QAM modulation. This configuration can be allocated from one or multiple frequency bands (multiband), simultaneously for one data connection of over 300 Mbps. Multi-carrier and multiband HSPA is standardized in 3GPP Release 8 through 11, and the standardization for eight carriers is expected to be completed by 2012. The eight-carrier product will be available from Nokia Siemens Networks by end of 2012.
Nokia Siemens Networks noted that it is driving the standardization of Long Term HSPA Evolution to achieve speeds of more than 650 Mbps.
“HSPA evolution is increasingly gaining importance as the technology is capable of achieving high data rates of over 300 Mbps,�? said Keith Sutton, head of the WCDMA business line for Nokia Siemens Networks. “Existing HSPA+ customers and new 3G entrants can deploy multi-carrier and multiband HSPA technology as it will allow them to offer the best user experience for bit-rate hungry applications such as the transfer of large files and mobile TV.�?http://www.nokiasiemensnetworks.com
