In the RHL RELIA project, we create remote laboratories for SDR (Software-Defined Radio), relying on the open-source GNU Radio. Most of the software and hardware developed in this project would work with any SDR kit that is supported by GNU Radio. Within the project, we have used two kits:
This document explains how to install the equipment and integrate it with RHL Relia. If you are interested in using RHL Relia with a different kit, please contact us.
Components
- ADALM-PLUTO Case V3.11: the case that can house 2 ADALM-PLUTOs ASCII STL File, Binary STL File, Fusion 360 Design Project
- Tag Holder V3.4: can be mounted to LabsLand Prism4 plates and holds customizable tags ASCII STL File, Binary STL File, Fusion 360 Design Project
- Tag RHL RELIA V3.4: name tag with RHL RELIA ASCII STL File, Binary STL File, Fusion 360 Design Project
- Tag RHL RELIA V4.1: name tag with RHL and LabsLand logos (Designed using Bambu Lab MarkerWorld MakerLab) ASCII STL File, Colored 3MF File
We recommend printing using a printer with a build volume of 300x300x100 mm or greater. PLA is sufficient for this application. A detailed printing profile can be found here.

There are two alternatives. We have done both during the RHL RELIA project:
- Creating our own structure
- Relying on a third party-structure (such as LabsLand Prism4)
In this section, we explain both approaches.
What you have to have is essential:
- A Raspberry Pi 4, fully powered with a proper USB charger (or any other charger, e.g., GPIO)
- The two SDR devices (e.g., two ADALM Pluto or two Red Pitaya)
- A camera (this is optional, but it helps students see that they are working with a real device and not with a simulation), and a camera management system (such as WILSP -paper-, motion or any other).
Then you need some space where to put it, such as some kind of shelves, etc., and you need to use a power strip and an ethernet switch to use it.
In the picture above, you can see one shelving unit, with two setups of ADALM Pluto (and their corresponding Raspberry Pi), without the Faraday boxes, and two Red Pitaya on the bottom right (not yet connected).
Alternatively, LabsLand provides the Prism4 structures, which are more compact and they already provide mechanisms for powering up two setups with a single power supply.
In the pictures above you can see 5 LabsLand Prism4, each of them containing two sets of remote laboratories (total 10 remote labs), each set of remote laboratories having 2 SDR devices each (20 SDR devices, each pair -transmitter and receiver- of SDR devices inside a Faraday Cage). Each Prism4 comes with two cameras, software to manage it, power supply and power cables, an ethernet switch, a light system and shadows (to prevent the light hitting directly on the remote laboratory) and relies on Phase Dock workbench modular bases to be able to adjust both the remote laboratory and the Raspberry Pi's.
