AT&T is investing in its wireless and wired network, including AT&T Fiber, Fixed Wireless Internet and other technologies, across the country.
The company is enhancing reliability, coverage, speed and overall performance for homes and businesses.
By building out the LTE network, AT&T is laying the foundation for 5G, the next advance in network technologies. The company's investments are also working to improve critical services that support public safety and first responders.
AT&T will build upon these investments as we work with the First Responder Network Authority to buildout FirstNet – Public Safety’s dedicated, nationwide communications platform. FirstNet is for America’s police, firefighters, EMS personnel and other first responders, helping them connect to the critical information they need when they need – every day and in every emergency.
