FirstNet, built with AT&T, has expanded its nationwide communications network to strengthen reliability and reach for first responders across the United States.
According to the organization, FirstNet added about 300,000 new connections in the third quarter of 2025, bringing its total to more than 7.8 million.
Around 300 additional public-safety agencies and organizations also joined the network, which now serves over 30,600 nationwide.
Sheriff Bob White, Retired from Brooksville, Florida, said: “All of this data is proof that first responders across the country continue to rely on FirstNet’s dedicated and secure communications platform to stay connected when it matters most.
“It’s about giving first responders the confidence and capability to protect the people they serve.”
FirstNet’s coverage now extends over 2.99 million square miles, expanding more than 250,000 square miles beyond its nearest competitor.
The network now reaches 99 percent of America’s first responders, according to the company.
It has also deployed 1,000 new Band 14 cell sites ahead of schedule as part of its 10-year buildout initiative.
These installations are designed to improve coverage, capacity and response speeds, particularly in rural and disaster-prone areas.
Sheriff White added: “Every new connection represents a stronger, safer community.”
The company said FirstNet continues to play an essential role in maintaining emergency connectivity during wildfires, hurricanes and major public events.
White continued: “As emergencies spanning from wildfires, hurricanes, and large-scale public events continue to challenge communities, FirstNet’s growth reinforces its goal to keep those on the front lines connected and ready.”
According to the company, these improvements reflect its ongoing commitment to ensuring responders can communicate effectively under all conditions.
The continued expansion of FirstNet holds practical value for emergency and disaster response leaders, communications managers and local public-safety agencies.
Increased coverage to 99 percent of first responders enhances interoperability between fire departments, emergency medical services and law enforcement during incidents spanning multiple jurisdictions.
The addition of 1,000 Band 14 cell sites provides greater resilience in rural and disaster-affected areas, improving access to secure data and voice networks during wildfire, hurricane and flood responses.
Network growth also benefits municipal emergency planners who rely on consistent, high-bandwidth communications for coordination and situational awareness during large-scale events.
