Ericsson has announced it will perform the first-ever demonstration of new HSPA multi-carrier technology for peak downlink data rates of 42Mb/s at the GSMA Mobile World Congress in Barcelona next week. The move was welcomed by its Australian operator customer, Telstra, which is prepping commercial launch of its HSPA+ network. Ericsson’s HSPA multi-carrier technology is expected to be commercially ready by the end of 2009.
