T-Mobile Claims a 5G Six-Carrier Aggregation “First”

T-Mobile said that it achieved the world’s first six-carrier aggregation call using sub-6 GHz spectrum on its live production 5G network. Working with Ericsson and Qualcomm Technologies, T-Mobile exceeded 3.6 Gigabits per second (Gbps) in the test. The carrier described this speed as fast enough to download a two-hour HD movie in less than 7 seconds. Higher speed and increased performance are the result of the 5G carrier aggregation in which T-Mobile combined multiple 5G channels. In this test, the carrier merged six 5G channels of mid-band spectrum: two channels of 2.5 GHz Ultra Capacity 5G, two channels of PCS spectrum, and two channels of AWS spectrum, creating an effective 245 MHz of aggregated 5G channels.
