For insanely high network speeds, T-Mobile is merging more than 5G bands.
T-Mobile isn't shy to brag about its 5G successes, and now
it's revealing yet another one: the business has reached 3Gbps network speeds
by merging three channels of mid-band spectrum on its 5G network. This appears
to be more than a ruse. Customers on T-network Mobile will be able to use
this technology "later this year," according to the company.
Those 3Gbps (or 3,000Mbps) speeds are getting close to
mmWave territory, which is the high-band, limited-range 5G that lets you
download a movie in seconds. Typical mid-band 5G speeds are approximately
200Mbps, which is regarded as quite good when compared to LTE. T-Mobile, on the
other hand, is tweaking behind the scenes to considerably increase those
speeds.
It does it by combining various swaths of bandwidth via carrier aggregation. Don't be fooled by the name "carrier"; this is T-Mobile utilizing its own airwaves. On some portions of its network, the company already utilizes similar technology to merge two 2.5GHz 5G channels, while this latest test boosts speeds with a third channel.
It's nothing new to use carrier aggregation to demonstrate
remarkable network speeds. Verizon has used the technology to showcase 4.2Gbps
speeds on its 5G network, which it plans to launch in 2020. T-Mobile, on the
other hand, claims to be the first to employ three-carrier aggregation with a
commercially available handset on a live, standalone 5G network: the Samsung
Galaxy S22. T-Mobile Galaxy S22 users will be "among the first" to be
able to enjoy this special taste of 5G when it becomes available in other
regions later this year.
