NSN ekes out HSPA+ performance

Nokia Siemens Networks today claimed to be the first to implement 3GPP-approved standards resulting in Continuous Packet Connectivity (CPC) for HSPA+ networks.

 At its simplest level, CPC is a set of features designed to boost the performance of HSPA+ networks by cutting interference. NSN claims its implementation boosts uplink capacity by five times, increases data rates 60%, and boosts smartphone battery life 15% (the latter by reducing interference in the downlink).

 The vendor also claims it has proven CPC as a means of tackling growing demand for data from an increasing number of smartphone users.

 Does anyone have any information on which other firms are working on this, and whether the standards are worth implementing as clamor for 4G increases?
