Radios are just one piece of the broad need for lower power chips, said Calhoun who conducts research in the area at the University of Virginia. “Today’s devices won’t get us to trillions of nodes people predict for IoT,” he said. The Internet of Things needs new lower power radios and a fresh approach to silicon design, said an expert with a startup designing IoT chips. “I think there’s a growing realization Bluetooth Low Energy and Zigbee are not the right solutions” because they consumer tens of milliwatts, said Benton Calhoun, co-founder of PsiKick...
