Slovak Telekom, in collaboration with Ericsson and Qualcomm, has successfully demonstrated an over-the-air LTE Advanced solution with data speeds of up to 900Mbps. The operator successfully tested speeds up to 300 Mbps in September 2014 on its 4G network before advancing to 375 Mbps in June 2015.
Ericsson RAN equipment installed and commercially used in Slovak Telekom’s network, and a Qualcomm Snapdragon X16 LTE modem, were used in the demonstration
The solution supports a maximum data throughput of 900Mbps by utilizing 50MHz three-carrier aggregation with 256 quadrature amplitude modulation (QAM), and by applying 4x4 multiple-input and multiple-output (MIMO) across 40MHz of spectrum.
Slovak Telekom started to build nationwide LTE network coverage in 2013. In order to improve customer experience, Slovak Telekom and Ericsson are cooperating on network speeds and quality enhancements in parallel while expanding LTE network coverage.

Slovak Telekom keeps the momentum of using the wide range of auctioned spectrum with an LTE Advanced demonstration in a commercial network in Slovakia. Once again, we have pushed the boundaries of our network to the next level, and after trialing 300Mbps and 375Mbps speeds in previous years, we have now undertaken a jump to higher speeds that can reach up to 900Mbps.
Mats Otterstedt, Head of Ericsson Central Europer
Following previous successful tests in the commercial network, today’s event is an important next step in the long-term cooperation between Slovak Telekom and Ericsson.
