T-Mobile US, working in association with Ericsson and Qualcomm Technologies, has achieved download speeds of 4.3Gbps using eight channels of millimetre wave (mmWave) spectrum. T-Mobile also aggregated four channels of mmWave spectrum on the uplink, reaching speeds above 420Mbps.

Ulf Ewaldsson, President of Technology at T-Mobile, commented: ‘We’ve always said we’ll use mmWave where it makes sense, and this test allows us to see how the spectrum can be put to use in different situations like crowded venues or to power things like fixed wireless access when combined with 5G Standalone.’

TeleGeography notes that T-Mobile has successfully bid on spectrum in the 24GHz, 28GHz, 37GHz and 39GHz bands since 2019, winning thousands of regional licences at auction.
