ULP Radios and Their Application in 5G IoT

Over the last two decades, computing has evolved from the laptop to the smartphone to today’s fledgling IoT devices. At each step, the number of devices per person increased exponentially, with IoT device estimates ballooning to upwards of trillions. Yet, this vision of "ubiquitous computing" is hampered by a continued reliance on batteries, presenting a significant barrier to realizing the vast potential of the IoT. As wireless communication typically accounts for the majority of an IoT device's power budget, advances in low-power RF can make significant headway in solving the IoT's power problem and moving towards a world of batteryless devices. This presentation focuses on the benefits and limitations of 5G for IoT devices, as well as the enabling technologies required to fully utilize 5G for the IoT. Notably, it will focus on recent advances by PsiKick and the University of Michigan in RF circuits and protocols that lowers the power consumption for wireless communication by several orders of magnitude. The result is the ability to deploy completely self-powered IoT sensors that can perform continuous monitoring across an array of applications without the need for batteries.
