On April 19, 2024, the University of Notre Dame celebrated the 125 year anniversary of the first known wireless transmission in the United States which was sent from the Basilica of the Sacred Heart on Notre Dame's campus to Bertrand Hall more than a mile away at Saint Mary's College.Since Professor Jerome Green’s initial forays into wireless research at Notre Dame in the 1890s, the University has built on his legacy and continued to invest in this essential area of research:Since 2010, the University’s growing research in this field has been organized through the Wireless Institute in the College of Engineering. It serves as an incubator for big ideas and large projects involving faculty from various disciplines around the University and the across the country.The Wireless Institute also leads SpectrumX, the world’s largest academic hub where radio spectrum stakeholders innovate, collaborate, and contribute to research and spectrum policy with the goal to maximize the social welfare of the radio spectrum itself. The center currently hosts 30 member institutions.
