The explosive growth of the Internet of Things (IoT) is helping to improve industrial processes, energy and city management, transportation and healthcare. This is thanks to the collection, analysis and exploitation of massive physical data, but amassing such data depends on the wireless connection of billions of cost-efficient battery-powered sensors. The scale at which this massive collection of data is envisioned is challenged by the limited energy and spectrum efficiency of today’s IoT wireless communication solutions.
Starting with the GreenOFDM algorithm, one of the project partners developed a fully programmable solution in the form of a multicore processor with a unique energy efficiency. The architecture is built on two world-class open-source projects (RISC-V and PULP), which is a very novel approach in the semiconductor industry. At system level, they combined an emulation of GreenOFDM with the open-source protocol stack long-range wide-area network to successfully realise point-to-point radio communications.
