O2 Czech Republic has deployed LTE Advanced (LTE-A) in selected locations, Telecompaper.com reported on July 7, 2014. The technology allows the usage of several frequency ranges simultaneously, which can increase speed. The technology is already available in the southeastern part of Vysocina. Using the frequency blocks of 10 and 5 MHz and dedicated devices, a download speed of 112 Mbps can be reached. O2 is also testing carrier aggregation with blocks of 10 and 15 MHz to support download speeds of up to 185 Mbps.

The operator works on increasing LTE network coverage and at the same time preparing its infrastructure for a further speed-up. Therefore, the operator has launched LTE Advanced in selected areas to test its possibilities in practice, said Petr Slovacek, director of the operations division. According to independent server DSL.cz, O2\'s 4G network is the fastest mobile network in the country. The operator is the second to launch LTE-A in Czech Republic, after T-Mobile a week earlier.
