(Telecompaper) Telekom Austria's subsidiaries A1 in Austria and Si.mobil in Slovenia are the first operators within the Group to enable their customers higher transmission speeds and higher bandwidths in selected locations. This will be possible thanks to the new LTE-Advanced technology known as Carrier Aggregation, based on the rolled-out LTE networks in Austria and Slovenia. Both subsidiaries have announced that they will start offering their customers LTE Carrier Aggregation in selected locations straight away. Based on this further development of the LTE technology, customers equipped with corresponding end-devices will benefit from average transmission rates that are twice the speed.
