T-Mobile is certainly not afraid to tout its own 5G performance, and as it should be, today it announces another milestone: by combining three channels of the midband spectrum on its 5G network, the company achieved 3Gbps network speeds. . This also appears to be more than a stunt — T-Mobile says the technology will be available to customers on its network “later this year.”
Those 3Gbps (or 3000Mbps) speeds are approaching the mmWave region — that’s the high-band, limited range of 5G that lets you download a movie in seconds. Mid-band 5G usually gets around 200Mbps, and that’s considered very good compared to LTE – but T-Mobile is doing a little tinkering behind the scenes to boost those speeds significantly.
More specifically, it uses carrier aggregation to combine different parts of the spectrum. Don’t be confused by the word ‘carrier’ either, this is T-Mobile with its own spectrum. The company is already using this technology to combine two 2.5GHz 5G channels on some parts of its network, while this most recent test boosts speeds with an additional third channel.
Using carrier aggregation to show off impressive network speeds is nothing new – Verizon used the technology before to demonstrate speeds of 4.2 Gbps on its 5G network by 2020. But T-Mobile claims to be the first to use three-carrier aggregation on a live, standalone 5G network with a commercially available device: the Samsung Galaxy S22. Incidentally, T-Mobile subscribers with a Galaxy S22 will be “one of the first” to take advantage of this unique flavor of 5G when it arrives in more places later this year.
