In a filing with the FCC this week, AT&T reiterated their commitment to being a leader in 5G. “AT&T has been busy laying the groundwork for its 5G deployment since 2016, and it is poised to introduce mobile 5G service in twelve cities by the end of the year,” they said. The filing also confirmed their plans to continue acquiring additional spectrum to use for their 5G network, and also provided insight on the plans of competitors like T-Mobile.
