The FCC posted mobile coverage maps Friday, based on information from providers. The maps show different coverage levels among the three major carriers and UScellular, with Verizon’s data coverage appearing to surpass AT&T and T-Mobile's. An FCC spokesperson said the…

maps are preliminary. “This preview of a mobile broadband and voice coverage map is the first produced under the criteria established by the Broadband DATA Act and reflects data voluntarily provided to the FCC,” a spokesperson emailed. “As the FCC builds its systems and continues to develop these maps, it will integrate into the process consumer and other stakeholder feedback intended to challenge and eventually verify the coverage.” Acting Chairwoman Jessica Rosenworcel acknowledged “much work remains.” The maps, by the Broadband Data Task Force, are available here. “Using improved systems and data, we can provide better information about where broadband service is and is not,” Rosenworcel said. Spokespersons for consumer groups said they were studying the materials. “Coverage maps are an endless battle that never seems to get solved,” said Summit Ridge Group’s Armand Musey. The coverage likely reflects areas with line of sight to a tower and are only preliminary, he said. Rural Wireless Association counsel Carri Bennet told us it’s not clear why the maps used data from only four providers. The FCC didn’t “share how the data was developed or what underlying formulas were used,” she said: The agency says it’s based on theoretical propagation modeling and not “real world coverage.” It's “a helpful first step towards generating more reliable coverage maps,” said Competitive Carriers Association President Steve Berry: “We look forward to reviewing the maps to assess whether they improve the reliability of the coverage predictions.” Detailed, granular maps "are critical to accurately identifying where there are gaps in broadband service and efficiently targeting public and private investment dollars,” emailed Joan Marsh, AT&T executive vice president-federal regulatory relations. “The LTE voice and data maps that Verizon provided and that the FCC published today are a first step toward better understanding the state of wireless broadband coverage in the country,” a Verizon spokesperson emailed. "As the wireless industry invested $30 billion in 2020 alone to deploy the infrastructure that powered our networks through the pandemic, CTIA and our member companies are continuing to work with our federal partners to help close the digital divide," the group said in a statement.
