The FCC just gave T-Mobile licenses to cover the 31MHz of 600MHz spectrum that it won at the FCC’s auction of low frequency airwaves. They travel farther and penetrate buildings better unlike high-frequency airwaves. By the end of 2017, T-Mobile will have over 1-million square miles of 600MHz spectrum. It already has 700MHz low-frequency spectrum that it uses for Extended Range LTE service.
Latest devices from Samsung and others will be there around the end of 2017 which will help T-Mobile customers to benefit from the features available with low-band spectrum.
Other than using the 600MHz spectrum to improve and enhance its LTE pipeline, T-Mobile will make use of some of this spectrum to build out the nationwide 5G network which is planned and announced by the firm during May.
