Easing the learning of signal processing and radio communications using low-cost software-defined radios in undergraduate, graduate and online courses

The surge of low-cost devices like the Raspberry PI or Arduino microcontrollers has enabled a lot of people to do many technical things by themselves. Domotics, automatics, security, maintenance and a large etcetera of fields have received a lot of attention from amateurs (the so-called ?maker movement?) and professionals as well. The realization of prototypes became cheaper and easier. The problem was that some fields still lacked of low-cost devices to accomplish this kind of easy prototyping and learning. One of these fields was radio communications, but this changed when a group of hackers realized that a USB dongle intended to receive TV signals could be used as a general purpose software-radio device. This device is the RTL-SDR. The goal of this paper is to assess some improvements on the way some engineering disciplines are taught, like signal processing, communications electronics, antennas, etc. To do so, we introduced a low-cost device, the RTL-SDR, to help students to learn all these concepts in a practical way. This device (which costs only 10 ?) was employed in many different courses: an undergraduate, graduate and a MOOC. The approach followed in the face-to-face training courses the approach was the following: instead of performing all the practical work in the laboratories, students were able to take away the RTL and do their homework out of the lab. This has improved the participation in class and students were also more skilled than previously when they only worked with real devices in the lab.
