Headquartered in Chicago, Illinois, the company is an 82%-owned subsidiary of Telephone and Data Systems, Inc. (TDS). Following the strategic sale of its regional wireless operations and select spectrum assets to T-Mobile US, Inc. which closed on August 1, 2025, the company rebranded as Array Digital Infrastructure, Inc. and transitioned into a standalone tower infrastructure platform. Array owns and operates a portfolio of approximately 4,400 cell towers across 19 states, enabling the deployment of 5G and other wireless technologies. In addition to its core tower leasing business, Array holds valuable noncontrolling investment interests in wireless partnerships (primarily managed by Verizon and AT&T) and retains a portfolio of wireless spectrum licenses, including C-band spectrum, which it continues to opportunistically monetize.
