Method of data modulation for WiFi devices so that they can communicate with non-WiFi devices
February 1, 2020The Internet of Things (IoT) offers users the opportunity to interact with objects used in daily life. Currently, the range of wireless interfaces is wide, which makes interoperability difficult and limits the real adoption of IoT. The ALLINONE project, developed by the Wireless Networks Group (WNG), offers a solution to provide interoperability between radiofrequency technologies and, at the same time, reduces energy consumption, which is another aspect of central importance in the rollout of IoT. The project is focused on Wi-Fi networks, but the results are applicable to other technologies.
A wake-up radio (WuR) system has been developed. This can wake up an electronic device when it is in sleep mode, that is, when it is not generating any form of active signal and therefore has minimal energy consumption. WNG has created software using WiFi technology, which can generate the “wake up” signal and thus control communication with the receiver and reduce the work cycle of the radio interface of the device, increasing the battery durability and energy efficiency. The system can be used for communication between devices that use different technologies. This is a key aspect to achieve interoperability between wireless interfaces.
ALLINONE was funded through the Spanish Ministry of Economy and Competitiveness and has a budget of 200,000 euros. The project has led to two patents.
