T-Mobile Poland has expanded its array of base stations with support for carrier aggregation, in a bid to dramatically increase the capacity of its LTE network.
The mobile operator first launched base stations with carrier aggregation – a technology that allows two or more carriers into a single data channel – in February 2016, eventually launching some 600 of them throughout that year.
In Q1 2017, T-Mobile Poland implemented the technology in 400 additional base stations.
“It took us twelve years to build our nationwide GSM network, eight years to build our UMTS network, and only 3 years to build our LTE network,” said T-Mobile Poland External Communications unit manager Konrad Mróz.
Currently, T-Mobile Poland has around 3,000 base stations that apply two-carrier aggregation for download speeds of up to 220 Mbps.
Nearly 800 base stations apply four-carrier aggregation (800 MHz, 1800 MHz, 2100 MHz, and 2600 MHz) for download speeds reaching up to 590 Mbps. According to the operator, its base stations with the highest speeds are located in Warsaw, Poznan, Katowice, Krakow, Tricity, and Wroclaw.
