O2 CR trials 4.5G in Prague as it looks to the 5G horizon

20 Dec 2016

Mobile network operator (MNO) O2 Czech Republic has carried out its first ‘real environment’ trial of 4.5G technology in the Brumlovka district of Prague, which it says will deliver theoretical speeds of up to 1.2Gbps. The operator continues to prepare for the advent of 5G in the coming years, and is using carrier aggregation (CA) of TDD and FDD in multiple frequency bands, and supplementing them with 4×4 MIMO technology and 256QAM. It points out, however, that the test 4.5G network does not yet support any end user device, saying that the first phones with the appropriate CAT16 standard to support multi-band CA, 4×4 MIMO technology and 256QAM should be on the market by the end of 2017. In total, the MNO is using 65MHz of bandwidth for the trial, broken down as: LTE-800 FDD (10MHz), LTE-1800 FDD (15MHz), LTE-2600 FDD (20MHz) and LTE-2600 TDD (20MHz).
