Ericsson has shown off a demo of multi-carrier HSPA with 168Mbps downlink and 24Mbps uplink The first demonstration showcased multi-carrier HSPA with 168Mbps on the downlink and 24Mbps on the uplink using a prototype consumer device and commercial network equipment.
Dual-carrier HSPA with 84Mbps was also demonstrated for the first time ever, using commercial network products. By using two 5MHz carriers in the connection to the same consumer, peak speeds of 84Mbps are reached, doubling the maximum speed that is offered today by the fastest commercial HSPA networks.
The first commercial network implementations of single-carrier HSPA with 42Mbps and dual-carrier HSPA with 84Mbps can be expected during 2011, followed by higher HSPA speed implementations in later on.
Future revisions of HSPA+ (evolved GSPA) support up to 168 Mbit/s using multiple carriers and up to 672Mbps is proposed for 3GPP Release 11 using advanced antenna techniques.
Qualcomm announced a new mobile chipset, the MDM8225. The MDM8225 brings full support for HSPA + Release 9 aka HSPA + 84Mbps. Qualcomm said that samples of MDM8225 are expected to be available in Q4 2011 with the first devices are expected to roll out sometime in 2012.
My prediction of Wireless superbroadband (50-1000Mbps) for 2009-2012 will be fulfilled with HSPA + 84 mbps.
