Qualcomm, in conjunction with its partners Telstra and Ericsson, has reported a new high in 5G download speeds. They have achieved 5 gigabits per second (Gb/s) at Australia's 5G Innovation Centre, using commercial Telstra infrastructure and up-to-date mmWave hardware. They include the new X60 mobile modem and third-gen QTM535 antenna.
