Remote sensing and wake-up is an important research area for future wireless communication system and particularly for wireless sensor network (WSN). Experimental results show that around 75% of the total power consumed from a typical wireless node is attributed to the radio transceiver. In radio transceiver the receiver power is almost equal to transmitter power. As the communication channel frequency increases, the receiver and Low Noise Amplifier power also increases. However this also results in higher communication link-budget which is a desirable factor in conventional Wireless Sensor Networks to get higher inter-node communication radius. To compensate the receiver power consumption, a secondary Low-Power, Low Frequency simplex Radio Frequency (RF) channel is proposed which is used to activate the primary RF communication subsystem. This paper describes an implementation of RF signaling and wake-up functionality in low power embedded active Radio Frequency Identification (RFID) Tag with data-logger functionality.
