- Telephone and Data Systems, Inc. (TDS) is a diversified telecommunications company headquartered in Chicago, Illinois, founded in 1969. The company operates primarily in the United States and provides communications services through three main business segments: UScellular Wireless, UScellular Towers (Array Digital Infrastructure), and TDS Telecom. TDS offers a range of products and services including wireless products and services; cable and wireline broadband with high-speed internet; TV entertainment solutions; voice services including traditional phone and VoIP advanced communications; dedicated internet service; data networking; hosted and managed services; and tower leasing to third-party carriers. TDS Telecom delivers fiber-powered internet with speeds up to 8 Gigabit, internet-protocol-based TV entertainment, and phone services to a mix of small to mid-sized urban, suburban, and rural communities nationwide.
In recent major developments, TDS completed the sale of its OneNeck IT Solutions and data center business to US Signal in 2024 to focus capital on expanding its fiber broadband program. In 2024, TDS also made a major strategic shift by entering an agreement with T-Mobile US for the acquisition of substantially all wireless activities of UScellular and specific spectrum licenses for approximately $4.4 billion, completing the transaction in 2025. This deal positioned TDS's tower business for growth and value creation. Additionally, TDS acquired TEAM Technologies, LLC, a significant data center services provider in the Upper Midwest, expanding its infrastructure capabilities. The company is executing an aggressive fiber broadband expansion strategy, having delivered over 27,000 marketable fiber service addresses and adding thousands of new residential broadband connections in 2025. Ken Dixon joined as President and CEO of TDS Telecom to lead these efforts.
TDS operates across the telecommunications industry, targeting consumer, business, and government customers in the U.S. Its subsidiaries include TDS Telecom, which services approximately 1.1 million connections, and Array Digital Infrastructure, which manages the tower leasing business. The company’s strategic focus centers on growing fiber broadband services, strengthening tower operations, and leveraging wireless infrastructure to enhance connectivity nationwide. Its comprehensive portfolio and operational focus on expanding fiber networks and managing wireless assets underpin its position as a key player in the U.S. telecommunications market.
