RHLab Interoperable Software-Defined Radio (SDR) Remote Laboratory

Educational remote laboratories, dedicated to radio frequency (RF) communications, represent an innovative effort aimed at bridging the gap between theory and practice. This advancement is even more empowered by the advent of Software-Defined Radio (SDR) technology, which allows students to create a wide array of prototypes for RF communication systems. The SDR community provides highly adaptable hardware that can be easily customized with just a few lines of code. Additionally, the availability of SDR hardware is extensive, offering various features tailored to users’ specific needs. One of the key advantages of the flexibility inherent in SDR technology is the shared libraries among its devices. This feature fosters interoperability which is the ability of different SDR devices or components to work together effectively. In this context, the Remote Hub Lab (RHL/RHLab) has been working to incorporate this functionality into the RHL-RELIA remote lab project. RHL-RELIA stands as a remote wireless communication lab, with its initial iteration based on the ADALM-PLUTO SDR. However, as it evolves, RHL-RELIA is incorporating other SDR devices, such as the Red Pitaya, which introduces unique features not found in the ADALM-PLUTO. This degree of diversification empowers students with a broad spectrum of choices, allowing them to select the SDR device that aligns most closely with their individual interests and educational requirements.
