T-Mobile activates first Voice Over 5G areas

Marking a milestone for its Standalone (SA) 5G network, T-Mobile activated commercial Voice Over 5G (VoNR) service in limited areas of Portland, Ore. and Salt Lake City for customers with the Samsung Galaxy S21 5G. T-Mobile plans to continue its VoNR rollout to many additional areas and 5G smartphones this year.

Customers connected to VoNR will notice slightly faster call set-up times, meaning less delay between the time they dial a number and when the phone starts ringing. 

More importantly, T-Mobile says VoNR brings it one step closer to truly unleashing its standalone 5G network because it enables advanced capabilities like network slicing that rely on a continuous connection to a 5G core.

“The commercial launch of the VoNR service is another important step in T-Mobile’s successful 5G deployment,” said Fredrik Jejdling, Executive Vice President and Head of Business Area Networks at Ericsson. “It demonstrates how we as partners can introduce 5G voice based on the Ericsson solution.”

“We are proud of our partnership with T-Mobile to bring the full capabilities of 5G to customers in the United States,” said Tommi Uitto, President, Nokia Mobile Networks. “Nokia’s radio and core solutions power T-Mobile’s 5G standalone network – and this VoNR deployment is a critical step forward for the new 5G voice ecosystem.”

O2 completes Germany's first 5G Voice over New Radio call

O2 has become the first German mobile network operator to make a Voice over New Radio (VoNR) call purely over its live 5G network. 

Currently, voice calls in all German mobile networks are completed using 3G and 4G technologies.

VoNR is currently possible in the live network at O2's first 5G mobile stations in Potsdam and Munich.

"Voice over New Radio will enable our customers to make optimum use of the network in the future. We are introducing the technology for voice transmission much faster than with the LTE standard. With 4G, the simultaneous transmission of voice telephony and data took about five years after the introduction of the mobile standard; with 5G, it took only a few months. We are proud to be the first operator to succeed with VoNR on our 5G network," says Mallik Rao, CTIO of Telefónica / O2.

ZTE and Qualcomm complete Voice Over NR Call in the 700 MHz band

ZTE and Qualcomm achieved the first 5G-enabled Voice over New Radio (5G VoNR) call over the 700 MHz band.

The call was performed in compliance with 3GPP Release 15 specifications over the 700 MHz spectrum band (n28) by utilizing ZTE’s 5G NR base station and a 5G smartphone form factor test device powered by a Qualcomm Snapdragon™ 5G Modem-RF System. The test validated the full functionality and high quality of the end-to-end VoNR services.

To fully support the commercial rollouts of 700 MHz in China, ZTE has stepped up its research and development efforts related to the 700 MHz band, and introduced a full range of end-to-end products, while working in tandem with Qualcomm Technologies in device development and interoperability tests of 700 MHz services to meet early demand for its commercialization in China.

“We at Qualcomm Technologies have achieved a series of milestones with industry leaders to support the progression of 5G, and this collaboration with ZTE showcases the Snapdragon 5G Modem-RF System’s leadership in supporting all key 5G spectrum bands as specified by 3GPP, a landmark in the evolution of 5G,” said Durga Malladi, senior vice president and general manager, 4G/5G, Qualcomm Technologies, Inc. “The success of VoNR over 700MHz shows how we can enable global OEMs and operators to deliver high-quality voice services without having to rely on VoLTE (Voice over LTE) or an LTE anchor, unlocking 5G’s ability to power worldwide connectivity capabilities.”

“We have been working closely with Qualcomm Technologies to drive the technical verification and commercialization in the development of 5G for a long term,” said Bai Yanmin, vice president and general manager of RAN products, ZTE. “ZTE has always maintained an industry-leading position in 5G networking solution. “The success of the 5G VoNR call over the 700MHz band has removed a key barrier to its full-scale commercialization and thus strongly supports the construction of 5G 700 MHz SA networks and helps offer more comprehensive 5G capabilities to more service providers, enterprise users and consumers.”
