T-Mobile makes its first 5G call on the 600 MHz spectrum in low band using the Qualcomm X55 modem

On Thursday, T-Mobile announced a milestone in its 5G deployment. In their Belleview, Washington, Lab, the carrier Qualcomm and Ericsson announced the completion of the first 5G data call. This was done using the Qualcomm X55 5G modem badociated with Ericsson 5G radio systems using T-Mobile's 600 MHz band (band 71).

The test is significant because it has been tested with a commercial modem. The Qualcomm X55 modem is a second-generation 5G modem that will eventually be integrated with commercially available smartphones.

Currently, T-Mobile's Extended Range LTE is synonymous with band 71. The company has spent $ 8 billion on this spectrum and customers benefit from better building penetration and a longer range over time. higher frequency bands.

Today's data call marks an important milestone in the ongoing deployment of 5G in the United States, paving the way for the launch of commercial networks and devices on the low-bandwidth FDD spectrum. This call demonstrates the ability to significantly increase 5G's global footprint and we look forward to continuing to work with industry leaders such as Ericsson and T-Mobile to unleash the full potential of 5G for consumers and new industries around the world. – Cristiano Amon, president of Qualcomm

While other operators (including T-Mobile) deploy and test 5G networks on a millimeter-wave spectrum (24 GHz or higher), T-Mobile's 600 MHz low bandwidth spectrum will not require as many 5G access. This solution is more practical for suburban and rural areas and should provide a more stable and consistent signal.

T-Mobile also mentions if Sprint merger is approved by US regulators. It will have the medium and low bands needed to "supercharge our network and provide a broad and deep and transformational 5G across the United States."
