Wake-up radio is an emerging technology for smart sensor networks and the Internet of Things with the ambitious goal of minimizing the power needed to communicate, thus enabling a new generation of applications. Wake-up radios should exhibit low latency coupled with high sensitivity, addressing capabilities with ultra-low power budget. They may be combined with existing radio transceivers and power management units to reduce the overall communication power while maintaining a high performance. This paper presents a 2.45 GHz and 868 MHz wake-up radio with the above mentioned characteristics. Dual band is exploited to increase the flexibility of the wakeup radio, allowing interoperability with the two most common bands used in Wireless Sensors Network and Internet of Things. Simulations results present a system with sensitivity as low as -55 dBm at 868 MHz and -53 dBm at 2.45 GHz.

Abstract
Wake-up radio is an emerging technology for smart sensor networks and the Internet of Things with the ambitious goal of minimizing the power needed to communicate, thus enabling a new generation of applications. Wake-up radios should exhibit low latency coupled with high sensitivity, addressing capabilities with ultra-low power budget. They may be combined with existing radio transceivers and power management units to reduce the overall communication power while maintaining a high performance. This paper presents a 2.45 GHz and 868 MHz wake-up radio with the above mentioned characteristics. Dual band is exploited to increase the flexibility of the wakeup radio, allowing interoperability with the two most common bands used in Wireless Sensors Network and Internet of Things. Simulations results present a system with sensitivity as low as -55 dBm at 868 MHz and -53 dBm at 2.45 GHz.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
