T-Mobile has completed its 5G network upgrades in Louisiana.

Completion of the multi-year investment totaling $290 million was announced this week by the US carrier and Louisiana Governor Jeff Landry.

The investment includes $50m towards an upgrade in its 5G service in the Greater New Orleans area.

T-Mobile said that the expansion provides access to 5G ultra capacity coverage to new geographical areas, and will provide faster Internet speeds for businesses, schools, healthcare providers, first responders, and anyone on T-Mobile’s network.

Providing an update of its overall coverage across the state, T-Mobile said its 5G service covers 99 percent of interstate highways, U.S. highways, and state routes across Louisiana.

It added that the investment has enabled it to add more than 300 new cell sites and nearly 1,870 upgrades to existing ones. Additionally, 92 percent of the state’s residents now have access to Mid Band-Ultra Capacity 5G, up 192 percent in just three years.

"Governor Landry's leadership in driving economic development in Louisiana, especially for those in more rural and underserved communities, aligns with T-Mobile's commitment to create the best possible network experience in the places where it matters most," said Ulf Ewaldsson, president of technology, T-Mobile.

"Our multi-year effort to enhance 5G connectivity across Louisiana is already bringing new opportunities for growth through enhanced speeds and better reliability in more places than ever before."

T-Mobile first launched its 5G service back in 2019 and claims to offer the most extensive coverage across the country, noting that its service can reach 98 percent of the population.

Last month, the telco was given a significant boost for its 5G enhancement plans after it was finally given the all-clear to activate its 2.5GHz spectrum.

T-Mobile paid $304 million for 7,156 licenses of 2.5GHz spectrum back in 2022 during US spectrum auction 108, but had been held up from activating due to a dispute with AT&T and Federal Communications Commission's (FCC) spectrum lapse.

The spectrum will boost T-Mobile's 5G network, by adding capacity to its network, with a particular focus on driving connectivity in rural areas.
