Array Digital Infrastructure, Inc.
An owner and operator of shared wireless communications infrastructure, Array leases space on its roughly 4,400 cell towers across the United States to wireless carriers, broadband providers, and government agencies that rely on them to deploy 5G and other networks. Born in 1983 as United States Cellular, a regional wireless carrier, the company sold its phone business to T-Mobile in 2025 and rebranded as Array—a name chosen to reflect the "array" of towers it now manages. Headquartered in Chicago, it remains a majority-owned subsidiary of Telephone and Data Systems.
