Wake-Up Radio is part of IEEE s standard: IEEE Std 802.11 (i.e., Wi-Fi(R)) and is being developed by the IEEE 802.11ba standards task group. Devices (like sensors) periodically wake up from sleep to receive information to maximize battery life. The longer the device stays asleep the less power it consumes, but the less information it can exchange (so it takes longer to exchange information latency.) In today's devices, low power consumption and low latency are conflicting goals. To increase battery life, a device needs to sleep more = increased latency.To exchange data with low latency, a device needs to sleep less = shorter battery life. IEEE Technology Report on Wake-Up Radio: An Application, Market, and Technology Impact Analysis of Low-Power/Low-Latency 802.11 Wireless LAN Interfaces discusses how to achieve low power and low latency at the same time.This document will be essential for manufacturers and users of sensors and devices for the Internet of Things, in order for them to make better business decisions related to these devices.
