T-Mobile US has announced that it has introduced 5G carrier aggregation (CA) across ‘much of its network’, combining frequencies in the 600MHz and 2.5GHz bands. The press release notes: ‘These capabilities are live across much of T-Mobile’s network today for customers with the Samsung Galaxy S21 and another popular flagship device, becoming more broadly available – with additional devices – in the coming months.’
In terms of overall 5G coverage, T-Mobile’s 600MHz ‘Extended Range’ 5G network now covers more than 310 million people across 1.7 million square miles, while the cellco’s 2.5GHz ‘Ultra Capacity’ 5G network covers more than 210 million people.
In an unrelated 5G development, T-Mobile notes that it recently achieved 1Gbps upload speeds by combining 2.5GHz spectrum with unspecified millimetre wave (mmWave) frequencies. The ‘5G Dual Connectivity’ test was carried out in conjunction with Ericsson and Qualcomm Technologies.
