The FCC voted last year to launch the 5G Fund for Rural America to expand 5G coverage into the many parts of country with poor cell coverage. It may turn out that market forces might mean that some of that subsidy won’t be needed since the big carriers are expanding into rural areas. A recent blog from Ookla documents the rural expansion of 5G. Ookla concludes that fierce nationwide competitive pressure is driving the carriers to look harder at rural areas to gain every possible customer.

Ookla, which collects a huge volume of speed tests, is one of the few companies that can look at carrier expansion using its own data. When Ookla sees multiple speed tests on 5G, it has definitive proof that coverage is present in an area. Ookla looked at the recent rural expansion from each of the three primary carriers.

T-Mobile. Ookla shows that T-Mobile has the largest rural 5G footprint today. T-Mobile claims it covers 323 million people, or 98% of U.S. households with 5G using its low-band 600 MHz spectrum. This low-band spectrum carriers for a greater distance than the spectrum used by other carriers. The company was required to expand coverage to 97% of the population as part of the agreement with the FCC when it purchased Sprint. I have to wonder about the 98% coverage. If you look closely at the FCC cellular maps, T-Mobile shows coverage of very slow speeds over a lot of rural America, and you have to wonder if this coverage is real enough to even use for voice calls.

T-Mobile also is the fastest carrier in much of the country, which came from the deployment of the 2.5 GHz spectrum that the company acquired with the Sprint purchase. The company has used the 150 MHz band of the spectrum to increase speeds in the top 100 markets in the country. We know that T-Mobile has rural plans since the company announced in 2024 that it is hoping to achieve a 20% market share in rural America by the end of 2025. That claim is bolstered by the pending close of the purchase of 30% of the spectrum and all 4.5 million customers of UScellular.

AT&T. A lot of the company’s rural expansion comes from FirstNet. This is a nationally funded program to create a nationwide first responder network. AT&T was awarded $6.5 billion to build the network and also given 20 MHz of 700 MHz spectrum. FirstNet brought AT&T a 25-year contract with the government. There is an expected $2 billion additional investment to upgrade the network to 5G everywhere.

One of the key requirements for FirstNet is that it must be made available to first responders in rural areas. This led AT&T to install FirstNet on all of its own towers and to build over 1,000 rural towers. AT&T announced in October 2024 that it has 6.4 million connections and 29,000 public safety agencies on the network. AT&T has also invested heavily in spectrum auctions and spent $37 billion the FCC’s C-band and 3.45 GHz auctions.

Verizon. Verizon doesn’t own much low-band spectrum that would give it coverage in rural areas. Instead, the company relied on a technology called Dynamic Spectrum Sharing (DSS) that allows one spectrum band to toggle between 4G LTE and 5G  in 1 millisecond increments. While it works, this didn’t give the company the boost it was hoping for.

Verizon’s rural strategy seems to be through acquisition, and the company has bought cell carriers operating in Kentucky, Iowa, New York, Pennsylvania, Missouri, and Montana. Verizon is also buying $1 billion of 850 MHz, AWS and PCS spectrum from UScellular.

Verizon is betting on the C-Band spectrum that it purchased in 2021 for $52 billion. It’s hoping that the 161 MHz band of spectrum will carry it into the future. The company has announced it intends to deploy more rural spectrum,

None of the carriers are likely to expand into sparely populated rural areas where coverage is often nonexistent. But the current expansion plans likely will bring cellular relief to a lot of rural areas, long before any solution might come from the FCC.
