A1, the domestic fixed and mobile unit of A1 Telekom Austria Group, has demonstrated mobile data rates of 1.5Gbps in cooperation with equipment vendor Nokia. A1 achieved the speeds through five-band carrier aggregation (5C) using spectrum in the 2600MHz, 1800MHz, 800MHz and 2100MHz bands, combined with MIMO and 256QAM. ‘Multiple carrier aggregation is already being used by A1 in Austria. As soon as enough devices support this technology combination, we will continue to roll it out for our customers in urban, high-capacity areas,’ commented A1’s CEO Marcus Grausam.
