WRC celebrates the 75th anniversary of the transistor, invented in December 1947 by American physicists John Bardeen and Walter Brattain. The transistor led to transistor radio development and countless small but powerful electronic devices and uses, laying the ground work for the Wireless Research Center, now known as WRC.

Just about everything electronic—every gadget or gizmo within reach—is full of transistors. Following the invention of the transistor—that revolutionized the field of consumer electronics—the Regency TR-1, invented by Texas Instruments electrical engineer Patrick Haggerty, was released in 1954, becoming the first commercial transistor radio. Since, the market has evolved from radios to smartphones to vehicles to wearables and a myriad of radio-based (wireless) technologies.


Since its founding in 2010, WRC has been at the forefront of wireless innovation—from helping network operators solve connectivity challenges through integrating emergency technologies, to present day Internet-of-Things possibilities and mission-critical applications for public safety and medical wearables.
