Greek mobile market leader Cosmote announced in a press release that it is pilot testing LTE-Advanced (LTE-A) technology under the ‘4G+’ banner to boost its mobile network speeds up to 300Mbps. Having acquired frequencies in the 800MHz and 2600MHz spectrums in October 2014 (becoming valid for commercial usage in February 2015), the operator demonstrated speeds in excess of 200Mbps that month using LTE Carrier Aggregation, while more recently claims to have recorded download speeds of more than 250Mbps in laboratory conditions. Now the OTE subsidiary is testing the performance of its 4G+ network and its ‘interoperability with the existing networks (2G, 3G, 4G)’ via pilot tests in Athens and Salonica. Cosmote hopes to launch the 300Mbps speeds commercially in selected areas during the first half of 2015. It currently operates 1800MHz LTE services covering around 65% of the Greek population.
