NSN Sees Upstream Gain with HSPA+ Continuous Packet Connectivity

Nokia Siemens Networks has tested Continuous Packet Connectivity (CPC) features that reduce interference on HSPA+ networks thereby providing five times more uplink capacity. This allows operators to support more smartphone users on HSPA+ networks. In addition, smart device batteries last 15% longer while people benefit from a 60% increase in data rates.



The tests included field testing using Nokia Siemens Networks’ Flexi Multiradio Base Station with commercial HSPA+ software and the company’s multicontroller as well as Nokia smartphones. These tests were conducted at a Nokia Siemens Networks Smart Lab in collaboration with experts from a tier-1 operator.



Continuous Packet Connectivity (CPC) is being standardized by 3GPP.



"High network interference levels pose a serious challenge to network capacity, considerably limiting the number of smartphone users that operators can add to their HSPA+ networks. These challenges are magnified with the ongoing rise in smartphone penetration,�? said Keith Sutton, head of the WCDMA business line for Nokia Siemens Networks. “Via extensive testing, we’ve established that Continuous Packet Connectivity serves as a powerful tool by countering these challenges and optimizing HSPA+ performance."http://www.nsn.com
