About WirelessUSA®

Founded as St. Louis Electronics Service Corporation in 1962, the company originally did business as St. Louis Electronics. Later as the company grew in the area it served, a new name, WirelessUSA was adopted. WirelessUSA has been supporting Motorola two-way radio products and infrastructure for more than 50 years.

Why would you select the highest quality communications equipment available today and then jeopardize your investment by purchasing from a dealer who is not authorized by the manufacturer of the equipment they sell?

Building Quality Relationships!
WirelessUSA® has successfully implemented radio communications systems for clients that include the Missouri State Highway Patrol, the St. Louis Police Department, the Illinois Department of Transportation, the St. Louis County Police Department, the Federal Bureau of Investigation, Anheuser-Busch Companies, the US Drug Enforcement Agency, Scott Air Force Base, The Boeing Company, and many more.
