Slovak Telekom claims to be the first operator in the world successfully to test HSPA+ 42 Mb/s technology in single-carrier mode, reports Telecompaper. Tests showed that the technology in single-carrier mode achieves results comparable with dual-carrier mode and measured data download speeds of up to 38 Mb/s. The tests were conducted in cooperation with Deutsche Telekom, Ericsson and Qualcomm. The operator currently is preparing the launch of commercial HSPA+ 42 Mb/s in dual-carrier mode.
