Crown Castle owns and operates approximately 40,000 cell towers, small cells and some 90,000 route miles of fiber as shared communications infrastructure across the United States.
Crown Castle owns and operates shared communications infrastructure across the United States: roughly 40,000 cell towers and about 90,000 route miles of fiber optic cable, along with small cell networks for dense and urban environments. The company, founded in 1994 and headquartered in Houston, Texas, describes itself as the nation's largest provider of shared communications infrastructure. It operates as a real estate investment trust.
Its infrastructure supports wireless carriers, wireless internet service providers, technology companies, venues, commercial real estate owners and tenants across sectors including healthcare and financial services. Cell towers and small cells provide the wireless layer; fiber networks carry voice and data traffic between carriers and end customers. The business model rests on leasing shared capacity to multiple users of the same asset rather than building dedicated networks for individual customers.
Technical domains at the company include cell tower networks, small cell networks and fiber optic networks. Crown Castle states its founding premise as the expectation that wireless connectivity would become essential to modern life and business, and frames its work around keeping people and communities connected in a mobile world.
