AT&T Subscribers Just Got a Significant 5G Speed Boost Due to New Spectrum

AT&T’s rapid activation of EchoStar’s 3.45 GHz spectrum spans 23,000 sites, boosting average download speeds by up to 80%, enhancing mobile and fixed-wireless service.

  • On Monday, AT&T activated EchoStar 3.45 GHz spectrum across nearly 23,000 cell sites, with service live in more than 5,300 cities spanning 48 states.
  • On Aug. 26, AT&T paid $23 billion to acquire about 30 MHz of 3.45 GHz mid‑band and roughly 20 MHz of 600 MHz low‑band from EchoStar and began using the spectrum under an interim lease before closing next year.
  • Early data indicate upgraded bands have increased download speeds by up to 80% for mobile service and 55% for AT&T Internet Air, while the 3.45 GHz band now supports FirstNet for first responders.
  • The upgrade expands mid-band capacity to support converged wireless and home internet, helping AT&T upsell Internet Air subscribers to fiber-optic broadband at no extra charge, while boosting long-term operating efficiencies and reducing future capital expenditures.
  • The move positions AT&T to expand North America's largest wireless footprint, as Boost Mobile abandons independent network plans and AT&T advances standalone 5G core and Open RAN initiatives.
