Qualcomm, ZTE Successfully Test Voice Call Over 5G

Qualcomm and ZTE today announced that they have successfully tested a Voice over New Radio (VoNR) call. VoNR is essential for the rollout of 5G SA (stand-alone) networks. All current 5G networks are NSA (non-stand-alone), meaning they only work as an add-on to existing 4G networks. On a 5G NSA network, all voice calls happen over the 4G network. With VoNR, 5G SA networks will be able to handle voice calls and operate independently of 4G networks. 5G SA networks will also be more efficient and unlock additional benefits of 5G such as lower latency. The milestone announced today was achieved using ZTE's 5G NR base station and a 5G smartphone form factor test device from Qualcomm.

T-Mobile recently announced that its mid-band 5G network now covers over 200 million people, a threshold that the industry acknowledges as "nationwide" coverage. (Mid-band 5G offers an ideal balance of fast data speeds and broad coverage compared to 5G in other bands.) In an interview with Phone Scoop, T-Mobile executives detailed how they plan to maintain the company's lead in mid-band 5G even as Verizon and AT&T launch mid-band 5G early next year.

Following C-Band 5G Debacle, FCC Considers Regulating Radio Receiver Performance

Apr 21, 2022
The FCC has launched an official proceeding to investigate how it can best address the issue of radio receiver performance. The FCC has historically regulated radio transmitters, but paid little attention to the technical aspects of radio receivers.

T-Mobile Launches 5G Voice

Jun 3, 2022
T-Mobile has achieved commercial launch of VoNR (Voice over New Radio), the key technology that enables a phone to operate 100% on a 5G network, including voice calls, instead of relying on a 4G network. For now, the service is available only in limited areas of Portland, Oregon and Salt Lake City.

Verizon Ready to Light up More Mid-Band 5G Using Band 48

Jun 14, 2022
Verizon has successfully tested 5G technology in two different modes within band 48, also known as CBRS. At 3.5 GHz, this valuable mid-band spectrum is close to the C Band spectrum that Verizon recently deployed.

T-Mobile Achieves 3 Gbps Using Standalone 5G in Mid-Band

Jun 14, 2022
T-Mobile has successfully tested 5G triple carrier aggregation (NR CA) using 5G standalone (SA) and mid-band spectrum, achieving an impressive downlink data rate of 3 Gbps. Triple CA is not new, but non-standalone (NSA) 5G requires that one of those three carriers be slower 4G, limiting potential data speeds.
