\tT-Mobile US teamed with top network and handset vendors on a series of standalone (SA) 5G tests to demonstrate end-to-end system readiness, furthering preparations for a commercial launch later this year.<\/p>\n

Along with Cisco, Ericsson, MediaTek, Nokia and Qualcomm, T-Mobile claimed several SA 5G milestones, including the first data session between commercial modems from different suppliers; a low-band voice call with LTE fallback; low-band Voice over New Radio (VoNR) call; and Video over New Radio (ViNR) call.<\/p>\n

It also completed the first VoNR and ViNR calls using a commercial device, the OnePlus 8 [1].<\/p>\n

The news comes as technology vendors battle to claim SA 5G firsts: Huawei was first out of the gates with a VoNR call in May 2019, though Qualcomm and ZTE subsequently claimed the first 3GPP standards-based variant in January.<\/p>\n

Last month, Ericsson, MediaTek and Oppo completed voice and video calls [2] using the new architecture.<\/p>\n

Rollout
\nT-Mobile says SA 5G will enable faster speeds and lower latency by eliminating network limitations associated with the use of 4G in non-standalone (NSA) operation.<\/p>\n

President of technology Neville Ray stated its trials \u201cmark a huge step forward for the entire wireless ecosystem\u201d.<\/p>\n

All tests used T-Mobile\u2019s 600MHz 5G network and newly-built SA core. During testing, SA and NSA 5G devices were able to maintain active sessions simultaneously on the same cell, it said.<\/p>\n

Rivals AT&T [3] and Verizon [4] are also pursuing SA rollouts in 2020.<\/p>\n
