Headquartered in Melbourne, Florida, the company has approximately $7 billion of annual revenue. It is the largest private-sector employer in Brevard County, Florida (approximately 6,000).

The company's Digital Telephone Systems (DTS) division was sold to Teltronics.
Dallas
The end of World War II left Dallas seeded with a nexus of communications, engineering, and production talent by companies such as Collins Radio Corporation. Decades later, the telecommunications and information revolutions still drive a large portion of the local economy. The city is sometimes referred to as the heart of "Silicon Prairie" because of a high concentration of telecommunications companies in the region, the epicenter of which lies along the "Telecom Corridor" in Richardson, a northern suburb of Dallas. The Corridor is home to more than 5,700 companies including Texas Instruments (headquartered in Dallas), Nortel Networks, Alcatel Lucent, AT&T, Ericsson, Fujitsu, Nokia, Rockwell Collins, Cisco Systems, Sprint, Verizon Communications, XO Communications and until recently CompUSA (which is now headquartered in Miami, Florida). Texas Instruments, a major manufacturer, employs 10,400 people at its corporate headquarters and chip plants in Dallas.
