T-Mobile conducts 800MHz 4×4 MIMO test in Czech Republic

13 Mar 2015

T-Mobile Czech Republic, the country’s largest mobile operator in terms of subscribers, has completed what it claims is the world’s first 4×4 multiple input, multiple output (MIMO) test in a low frequency (800MHz) band. The pilot project commenced in October 2014 in the municipality of Petrovice, near Prague, and was conducted by T-Mobile, its parent company Deutsche Telekom (DT), Chinese technology vendor Huawei and US-based antenna firm SkyCross.

Vladimir Klein, chief technology officer at T-Mobile, commented: ‘The findings of this test will be used by T-Mobile and the entire Deutsche Telekom Group to deploy the most innovative and efficient LTE-Advanced network. They will also help us to further improve the voice-over-LTE (VoLTE) technology, which we want to offer to our customers in the first half of this year.’

4×4 MIMO technology doubles the number of transmitters on mobile antennas from two to four, supporting up to four independent data streams. By using multiple antennas at both the transmitter and receiver ends, MIMO technology increases the efficiency of spectrum utilisation.
