Mobile operator O2 Slovakia has said it is planning its biggest annual investment this year since it entered the local market. The firm’s CEO Peter Gazik has said that O2 will be spending around EUR50 million (USD57 million) in 2016, primarily on the expansion of its 4G networks. It wants to increase LTE coverage from approximately 25% currently to 60% by the end of the year. Local news portal Mobilmania also reports that O2 is looking at deploying voice-over-LTE (VoLTE) technology, though it is waiting for more devices to support the service before it considers a commercial launch. O2 is also looking to compete with the country’s converged fixed-mobile operators such as Slovak Telekom, Orange Slovensko and SWAN/4ka, having recently launched its own fixed internet and IPTV services.
