T-Mobile 5G is ready for a massive speed upgrade

T-Mobile has achieved speeds in excess of 3 Gbps on its standalone 5G network (5G SA) by combining multiple spectrum channels using carrier aggregation.

The US mobile operator combined two batches of spectrum in the 2.5 GHz band with another in the 1900 MHz band to effectively create 210 MHz mid-range capacity to achieve the desired transmission speed.
