Power can be supplied via energy harvesting technology.
Fraunhofer's activation receiver technology significantly increases the operational lifespan of wireless receiving systems. In terms of power consumption and data rates, the device can be configured with a wide variety of options, thus ensuring several years of battery life or completely autonomous operation through energy harvesting.
The activation receiver continuously monitors the wireless channel—without the use of a microcontroller—and recognizes two independent activation patterns. Besides pure wake-up mode, it can also receive encoded data. Furthermore, selective activation of specific wireless nodes can be performed using a 16-bit address.

Current prototypes, based on 130 nm CMOS technology, operate in the 868 MHz and 2.4 GHz frequency bands with
a millisecond response time When operating in the standard configuration at a data rate of 1 kbit/s, power consumption is reduced to a mere 3 µA with a response time of 32 ms. Wide range of applications:
Fraunhofer trigger receiver technology represents a key technology for the "Internet of Things" and "smart object" environments. It offers utility in a wide range of applications, including building automation, smart lighting, electronic tags, remote maintenance, remote control, and wireless sensor networks.
