Short Description

During recent years there is a strong trend towards saving energy reduction the power consumption of electrical devices. To achieve this goal, efficient energy management strategies must be implemented through selecting optimal circuits, technologies and techniques to save energy. Traditionally, the usage stand-by mode when the devices are not necessary are the most popular solution to save energy. In fact, in stand-by mode the devices are consuming order of magnitude less power than in active mode, and this allows to do not waste precious energy. However, it is important to implement mechanisms and electronics circuits to wake up the system quickly and with high reliability and to develop controllers to make it possible. Wake-up circuit can efficiently wake up the devices when such a request is sent from a remote host. Fully passive or nano-power wake up receiver can reduce the power consumption of electrical devices while still keeping its wake up time low. Another role of the wake-up system is that based on "intelligence" to select a specific device which has to be woken up. The two most popular technologies used in the wake up technologies are the radio frequency and infrared transmission. Infrared (IR) remote controls have proven being a cost efficient solution for controlling many kinds of electronic devices: Home entertainment, air condition, home lighting. For this reason they can provided an useful solution especially in smart and green home application.

The main objective of this project is work in hardware and software with infrared wake up radio technology. The candidate student will work with specific infrared transceiver to send commands and wake up packet that will be listening from the wake up infrared receiver. The hardware part will include also a redesign of part of the wake up receiver to increase the range or add digital part to perform an addressing detector. The software part will be both in transceiver and receiver and it could include . Measurements on the performance of the system will be performed from the students in order to evaluate the distance, power consumption, reliability, functionality.
