Vodafone Portugal unveiled a prototype 5G handset at the sixth annual ‘Big Smart Cities’ event in Lisbon and conducted a 5G video call between Portugal and the United States. The device was connected to a pre-commercial end-to-end 5G Massive MIMO network built by Ericsson and Qualcomm, which utilises the 3.6GHz spectrum band. Vodafone Portugal CEO Mario Vaz called the demonstration a ‘historic milestone’ for the cellco.
According to TeleGeography’s GlobalComms Database, back in October 2017 Vodafone successfully achieved downlink transmission speeds of up to 20Gbps in a ‘5G’ trial carried out in association with Ericsson. That demonstration took place at Vodafone’s headquarters in Lisbon, and utilised multi-user MIMO technology alongside beamforming, a signal processing technique that directs signals from multiple antennas towards where mobile customers are situated.
