Projects and Research at CEI-UPM

▪ High Performance Reconfigurable Cookie

▪ Wake-Up radios for Ultra Low Power WSN

▪ Wireless Sensor Network operating in the 868 MHz Band

▪ Planning Tool for Wireless Sensor Networks

But… Something else is needed…Due to the challenges and requirements ofdeveloping Wireless Sensor Networks, it isnecessary to implement a system for testing andevaluating all these experiments and newtechnologies in a realistic environment.
