Slovak Telekom has launched a 4G LTE network in five cities in Slovakia, more locations will follow soon. According to Ericsson, it is the sole vendor for the LTE radio network, which is based on the multi-standard RBS 6000 base station. 

The network operates at 1800MHz and offers a maximum theoretical speed of 73Mbps download and 23Mbps upload. Circuit-switched fallback (CSFB) ensures that voice calls and text messages are delivered to LTE devices through the use of a 2G/3G circuit-switched network.

Ericsson is the also supplier of 2G and 3G radio, as well as circuit core hardware and software, including IMS (IP Multimedia Subsystem). With the Ericsson IMS Slovak Telekom plans to evolve its current voice business to support VoLTE in the future. This will enable HD voice, video calling over LTE and other new flexible communication services. Ericsson is also providing managed services for Slovak Telekom's fixed network operations.
