Taking Cellular IoT Energy Efficiency to the Next Level

• We present and analyze a new approach to improve energy efficiency in cellular IoT devices. The new approach consists of employment of ultra low power wake-up receivers in combination with robust non-coherent modulation. The results show that we can achieve very competitive power consumption, reducing it by up to 50 times, compared to two conventional power saving solutions we use as references. These large power savings are particularly important when the device needs to be highly available, in terms of wake-up time, and has a tight delay requirement. In these situations, the large power savings can be traded for shorter duty-cycle lengths. This translates to correspondingly shorter wake-up delays and our results show that they can be reduced well over 100 times, at the same average power consumption.
