T-Mobile US completes 600MHz 5G call in Las Vegas

8 Jan 2019

T-Mobile US has teamed up with vendor duo Ericsson and Intel at the CES 2019 event in Las Vegas to stage what it claims is ‘the world’s first 5G data call and video call’ on a live 600MHz network. The cellco also accomplished a tri-band 5G video call with three users on different spectrum bands: 600MHz, 28GHz and 39GHz. T-Mobile’s press release notes: ‘Low-band 600MHz spectrum delivers a broad layer of 5G and provides much needed balance to millimetre wave (mmWave) – which is an important piece of the 5G puzzle – but has limited coverage (less than a square mile) and is unable to pass through most objects, like walls.’

TeleGeography notes that T-Mobile expects to launch its nationwide 5G network in 2020 and is in the process of deploying 5G-ready equipment as it rolls out its 600MHz ‘Extended Range LTE’ network, which is already live in more than 1,500 cities and towns in 37 states and Puerto Rico.
