AT&T occupies a cluster of office buildings on Imperial Highway, associated with the adjacent Hughes communication satellite production plant, now operated by Boeing. AT&T was the primary communication company in the nation for many decades, and worked closely with Hughes and the federal government in developing its space-based assets, which included systems dedicated to military command and control communications. In 2015 AT&T bought Hughes’ Direct TV, headquartered here, including its fleet of 12 satellites that provide coverage over North America. Also located in the AT&T towers here is an office of Booz Allen Hamilton, a nationwide company that provides computing and intelligence services to the federal government, including the NSA, which has a deep role in satellite-based communications.
