On Thursday, T-Mobile announced an important milestone in its 5G deployment. At its Belleview Laboratory, Washington, Qualcomm and Ericsson announced they had made the first phone call for 5G data. This was achieved through the Qualcomm X55 5G model coupled with Ericsson's 5G radio systems using the T-Mobile 600MHz band (Band 71).
The test is significant because it was tested using a commercial modem. The Qualcomm X55 is a second-generation 5G modem that will eventually be built into ready-made smartphones.
Currently, T-Mobile's Advanced LTE Range is synonymous with Group 71. The company has paid $ 8 billion for this spectrum, and customers benefit from better penetration in the building and a longer range than the higher frequency bands.
Today's data call marks an important milestone in the continued penetration of 5G in the United States, paving the way for the launch of retail networks and devices on the low-frequency FDD spectrum. This call demonstrates the opportunity to dramatically increase the global footprint of 5G and we look forward to continuing our work with industry leaders such as Ericsson and T-Mobile to unlock the full potential of 5G for consumers and new industries around the world. – Cristiano Amon, President of Qualcomm
While other operators (including T-Mobile) are running and testing 5G networks on the mmWave (24GHz and up) spectrum, Tiger's 600-megahertz low-frequency spectrum will not require as many 5G access points. This solution is more practical for suburban and rural areas and should offer a more stable and consistent signal.
T-Mobile also mentions if Sprint merger is approved by US regulators, it will have the need for "low and medium frequency" to "fill our network and deliver broad and profound 5G transformation in the US"
