Wireless communication networks in the gigahertz band could open up new high-speed communication capabilities and extremely small Internet of Things devices. #IoT Most wireless communication uses radio waves, but the airwaves are getting crowded. Tapping into the terahertz band, another area of the electromagnetic spectrum, could open up more and faster communication. "For wireless communication, the terahertz band is like an express lane. But there's a problem: there are no entrance ramps," says Josep Jornet, PhD, assistant professor in the Department of Electrical Engineering at the University at Buffalo School of Engineering and Applied Sciences. Jornet and co-investigators Jonathan Bird and Erik Einarsson are working on “the Internet of Nano-Things,” nanoscale radios made of graphene and semiconducting materials that could speed up IoT devices for computing, medical devices, civil engineering, and other industries that can benefit from high-definition, real-time streaming. "We'll be able to create highly accurate, detailed, and timely maps of what's happening within a given system. The technology has applications in health care, agriculture, energy efficiency -- basically anything you want more data on," Jornet said. # graphene
