  Ultra-Low Power Wakeup Radios And The Internet Of Things

  The growth of the Internet of Things (IoT) is expected to accelerate in the coming years, propelled by the lower cost and increasing connectivity of the network. Many of the communication devices for the IoT will have power constraints, due to their small size and the requirement to operate off small batteries for long periods of time. This paper will examine some of the requirements of such low power communication systems, the need for low power wakeup radios with example applications, and a comparison of candidate technology.
