Crown Castle

Crown Castle is a shared communications infrastructure company that owns, operates, and leases cell towers across the United States. Organized as a real estate investment trust and publicly traded, it describes itself as the only large US-focused pure-play tower company, with roughly 40,000 towers in its portfolio. Wireless carriers and other providers lease space on its towers and rooftop sites to deliver the coverage people rely on for calls, data, and emergency service.

The company has worked since 1994 with carriers, businesses, technology companies, governments, and communities to support wireless networks. Its directory listing for Harvard Square promoted small cell upgrades to improve coverage and public safety in the busy square. Crown Castle has since sold its fiber, small cell, and DAS businesses and now concentrates on towers and colocation, helping providers find and lease sites through an interactive map.
